Answer:
GridBagLayout,FlowLayoutManager
Explanation:
LayoutManager interface is the interface used for laying out containers.Components like Button,text boxes are placed by Layout Manager,it is used to determine size and position of components in a container.
We can implement this interface via many classes like -
SpringLayout, SynthScrollBarUI, ViewportLayout , FlowLayout, GridBagLayout, GridLayout etc.
GridBagLayout-This layout arranges the components in vertical,horizontal or in baseline irrespective of their size.The orientation of the GridBagLayout depends on the container's ComponentOrientation property.
GridBagLayout is associated with an instance of GridBagConstraints which manages each component.
FlowLayoutManager-This layout arranges the components in a directional flow. The alignment of line is determined by componentOrientation.
ComponentOrientation .LEFT_TO_RIGHT
ComponentOrientation.RIGHT_TO_LEFT
Given an array A of n + m elements. It is know that the first n elements in A are sorted and the last m elements in A are unsorted. Suggest an algorithm (only pseudo code) to sort A in O(mlogm +n) worst case running time complexity. Justify.
Answer:
Explanation:
We can divide array A into two arrays B , C
B would contain the sorted n elements.
C would contain the unsorted m elements.
Now we can sort C using merge sort with worst time complexity mlogm.
When you will have array C sorted you can concatenate with B and put it back in A.
A jeweler designing a pin has decided to use five stones chosen from diamonds, rubies, and emeralds. In how many ways can the stones be selected?
Answer:
3,125 different possible ways
Explanation:
Great question, hopefully i can shed some light on the situation. There are a total of 5 stones. One by one they are randomly picked out of the bag. We need to find how many possible combinations there are for picking the stones out of the bag. We can solve this by raising the amount of stones in the bag to its own power like so,
[tex]5^{5} = 3,125[/tex]
So now we can see there are 3,125 different possible ways of selecting the stones.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Fields are used to store all the data in a database.
Fields are used to store all the data in a database. The correct option is C.
What is a database?A database is a collection of data that has been organized to make it simple to manage and update. Data records or files containing information, including as sales transactions, customer information, financial data, and product information, are often aggregated and stored in computer databases.
A database field is a collection of identical data values in a table. It is also known as an attribute or a column. Most databases also permit complicated data storage in fields, including images, whole files, and even movie clips. A lot does not necessarily have simple text values just because it supports the same data type.
Therefore, the correct option is C. Fields.

You can initialize more than one variable in a for loop by placing a(n) ____ between the separate statements.
a.
equal sign
b.
comma
c.
period
d.
semicolon
Answer:
comma
Explanation:
The for loop is used to execute the specific statement again and again until the condition is false.
The syntax:
for(initialization;condition;increment/decrement)
{
statement;
}
In the initialization, we an initialize more than one variable by using the 'comma' as separator.
similarly for condition and increment/decrement part as well.
for example:
for(int x = 0,y = 0;x<5,y<5;x++,y++)
{
statement;
}
we can used as many as possible by using comma
. What happens when you serialize an object? What happens when you deserialize an object?
Answer: serialize means to convert a java object to byte stream and deserialize means to convert the byte stream again to java object.
Explanation:
Both of these functions are present in java.io library. we perform serviceable to java object in order to send it across the network where we can it can be stored in the hard disk because java object cannot be sent across the network to be stored in hard disks. Similarly deserialize enable to get the java object from the byte stream across the network

SQL commands can be classified into three types. Which isNOT an SQL command type?
1 DDL
2 DML
3 DGL
4 DCL
Answer:
DGL
Explanation:
SQL stands for structured query language which is used to interface with the database.
Let discuss the options:
1. DDL: This comes in the category of SQL and it stands for data definition language. This allows using CREATE, DELETE, DROP, ALTER, etc. of the table in the database.
2. DML: This comes in the category of SQL and it stands for data manipulation
language. This allows the user to use the INSERT, DELETE, UPDATE command which help to manipulate the data in the table.
3. DGL: This is not a part of SQL.
4. DCL: This comes in the category of SQL and it stands for data control language which allows the user to use ALTER PASSWORD, GRANT, REVOKE like command which helps the user to control access the data in the database.
Therefore, the correct answer is DGL.
Database applications are seldom intended for use by a single user.

Define the following variables (in a new file and a new main() function):
• Integer value a and b
• Pointer variable p and q (pointers to integer values)
• Set the value of a to 5 and value of b to 7
• Set p to point to a and q to point to b (in other words assign the address of variables to pointers)
Answer:
#include<stdio.h>
int main()//driver function
{
int a=5;//initializing variable a
int b=7;//initializing variable b
int *p,*q;//declaring pointers p and q
p=&a;//assigning the address of a to p
q=&b;//assigning the address of b to q
printf("value of a is %d\n",a);
printf("value of b is %d\n",b);
printf("value of pointer p is %d\n",*p);
printf("value of pointer q is %d\n",*q);
printf("address of a is %d\n",&a);
printf("address of b is %d\n",&b);
return 0;
}
Output
value of a is 5
value of b is 7
value of pointer p is 5
value of pointer q is 7
address of a is -783856608
address of b is -783856604
When a function uses a mixture of parameters with and without default arguments,
the parameters with default arguments must be defined _________.
Answer: after the required parameters.
Explanation:
Default arguments in a function should be defined after the required parameters because the required parameters are necessary but default arguments are not. If mixed parameters are allowed it will be very hard for the compiler to to judge which value matches which argument so there will be syntax error.

In java you can use pareDouble(string str) to convert the string into double.
for example if you have string like this.
string str = [tex]"16.45" ;[/tex]
then you can use
double mydouble = Double.parseDouble(str);
print(mydouble); //it will print out 16.45

Write a Java program that calculates and prints the monthly pay check for an employee. The net pay is calculated after taking the following deductions:
Federal Income Tax: 15%
State Tax: 3.5%
Social Security Tax: 5.75%
Medicare/Medicaid Tax: 2.75%
Pension Plan: 5%
Health Insurance: $75.00
Final answer:
A Java program can calculate an employee's net pay by deducting federal, state, Social Security, Medicare/Medicaid taxes, pension plan contributions, and health insurance costs from the gross pay. The net pay is then output as the amount the employee would receive in their paycheck.
Explanation:
To calculate the net pay for an employee after deductions, we need to write a Java program that considers the following deductions: Federal Income Tax at 15%, State Tax at 3.5%, Social Security Tax at 5.75%, Medicare/Medicaid Tax at 2.75%, a pension plan deduction at 5%, and a fixed amount for health insurance at $75.00.
Here is a simple example of how this Java program might look:
public class PaycheckCalculator {
public static void main(String[] args) {
double grossPay = 5000; // Example gross pay
double federalTax = grossPay * 0.15;
double stateTax = grossPay * 0.035;
double socialSecurityTax = grossPay * 0.0575;
double medicareTax = grossPay * 0.0275;
double pensionPlan = grossPay * 0.05;
double healthInsurance = 75;
double netPay = grossPay - (federalTax + stateTax + socialSecurityTax + medicareTax + pensionPlan + healthInsurance);
System.out.println("Net pay: $" + netPay);
}
}
This program calculates each of the deductions based on the gross pay, subtracts them from the gross pay, and prints out the resulting net pay.

write a program that convert binary number to decimal. I mean the input should be binary number and the output decimal number!!.
Answer:
#include<iostream>
#include<math.h>
using namespace std;
//main function
int main(){
//initialization
long b1;
int d1=0,count_pos=0;
//display the message
cout<<"Enter the binary number: ";
cin>>b1; //store the value
//loop for take the digit one by one
while(b1!=0){
int rem1 = b1%10;
d1 = d1 + rem1*pow(2,count_pos);
count_pos++;
b1 = b1/10;
}
//display the output
cout<<"The decimal number is: "<<d1<<endl;
}
Explanation:
Create the main function and initialize the variables. Then, display the message on the screen by using the instruction cout and then, store the input enter by the user into the variable. Here, the variable declares with type 'long' because of the size of the input.
After that, we take a while loop for splitting the binary number into the digits and then we can do the operation.
Let's understand how you can convert binary to decimal with an example:
let the binary number is 1001:
decimal number is [tex][tex]1*2^{3}+0*2^{2}+0*2^{1}+1*2^{0}=9[/tex][/tex]
we put the same algorithms in the code. split the number into digit and then multiply with n raised to the power of 2 here, n is the position of digit from left to right.
NOTE: Position starts from zero.
and then, add the values. this process continues until the number is not zero.
After that, display the output on the screen.
Convot the following biliary number into decimal form using any method ? (1010.100)2

Handy method you can find searching google images, and I originally learned
from some guy teaching an online java course.
.1 --> 1 * 2^(-1) = 0.5
0 --> 0 * 2^(0) = 0
1 --> 1 * 2^(1) = 2
0 --> 0 * 2^(2) = 0
1 --> 1 * 2^(3) = 8
0.5 + 2 + 8 = 10.5
If for some reason it isn't very clear, just take the number, (x) and multiply it
by two to the power of the position it is in. (e.g. first number before decimal point is 0, second 1, etc).
Instructions
Write a program that prompts the user to input a positive integer. It should then output a message indicating whether the number is a prime number. (Note: An even number is prime if it is 2. An odd integer is prime if it is not divisible by any odd integer less than or equal to the square root of the number.)
Answer: The c++ program to determine if the input number is prime is given below.
#include<iostream>
#include<math.h>
using namespace std;
int main() {
int num, n;
int prime=0;
int i=3;
cout<<"This program determines whether the number is prime." <<endl;
do
{
cout<<"Enter any positive number."<<endl;
cin>>num;
if(num<=0)
cout<<"Invalid input. Enter any positive number."<<endl;
}while(num<=0);
n=sqrt(num);
if((num==1)||(num==2))
{
cout<<"The input "<<num<<" is prime."<<endl;
}
else if(num%2==0)
{
cout<<"The input "<<num<<" is not prime."<<endl;
}
else
{
do
{
if(num%i == 0)
prime += 1;
i++;
}while(i<n);
if(prime>1)
cout<<"The input "<<num<<" is not prime."<<endl;
else
cout<<"The input "<<num<<" is prime."<<endl;
}
return 0;
}
OUTPUT
This program determines whether the number is prime.
Enter any positive number.
-9
Invalid input. Enter any positive number.
Enter any positive number.
0
Invalid input. Enter any positive number.
Enter any positive number.
47
The input 47 is prime.
Explanation: This program accepts numbers beginning from 1. Any number less than 1 is considered as invalid input.
The test for prime is done using multiple if-else statements.
If number is even, it is not prime. Any number divisible by 2 is an even number. Except 2, it is even but also prime since it is divisible by itself only.
For odd numbers, number is divided by all odd numbers beginning from 3 till square root of the input. We first calculate and store square root of input.
n=sqrt(num);
An integer variable prime is initialized to 0. This variable is incremented each time the number is divisible by other number.
int prime=0;
do
{
if(num%i == 0)
prime += 1;
i++;
}while(i<n);
Since prime number is only divisible by itself, all the prime numbers undergo this condition and hence, value of prime variable becomes 1.
The 0 and 1 values of variable prime indicate prime number. Other greater values indicate input is not prime.
if(prime>1)
cout<<"The input "<<num<<" is not prime."<<endl;
else
cout<<"The input "<<num<<" is prime."<<endl;
Python program checks if a positive integer is prime; uses a separate function to perform the primality test.
Here's a Python program that prompts the user to input a positive integer and then outputs a message indicating whether the number is a prime number:
```python
import math
def is_prime(n):
if n <= 1:
return False
if n == 2:
return True
if n % 2 == 0:
return False
max_divisor = math.isqrt(n)
for i in range(3, max_divisor + 1, 2):
if n % i == 0:
return False
return True
def main():
num = int(input("Enter a positive integer: "))
if is_prime(num):
print(f"{num} is a prime number.")
else:
print(f"{num} is not a prime number.")
if __name__ == "__main__":
main()
```
Explanation:
1. The `is_prime` function checks whether the given number `n` is a prime number.
2. It first checks if the number is less than or equal to 1, in which case it returns False.
3. It then handles the case for the number 2 separately, as it is a prime number.
4. For odd numbers greater than 2, it iterates through odd divisors up to the square root of the number to check for divisibility.
5. If the number is divisible by any of these odd divisors, it returns False; otherwise, it returns True.
6. In the `main` function, the user is prompted to input a positive integer, and the result of the `is_prime` function is printed accordingly.
Write a recipe that stores the sum of the numbers 12 and 33 in a variable named sum. Have your recipe display the value stored in sum.
Answer:
#include<iostream>
using namespace std;
int main(){
int sum = 12+33;
cout<<"The sum is: "<<sum<<endl;
}
Explanation:
First include the library iostream in c++ program for input/output.
Then, create the main function and declare the variable sum as integer type and store the sum of two given values.
After that, display the result store in the sum variable on the screen by using the instruction cout.

Given a int variable named callsReceived and another int variable named operatorsOnCall write the necessary code to read values into callsReceived and operatorsOnCall and print out the number of calls received per operator (integer division with truncation will do).
// c++ code to read the recieved calls
cout<< " Enter the calls recieved :";
cin>>callsRecieved;
cout<< " Enter operator on call : ";
cin>>operatorsOnCall;
// calculating the call per operator
calls_per_operator = callsRecieved/operatorsOnCall;
// printing the vaule.
cout<<" Calls recieved per operator are : " << calls_per_operator <<endl;
Final answer:
To find the number of calls received per operator, read inputs for callsReceived and operatorsOnCall, then divide callsReceived by operatorsOnCall using integer division and print the result.
Explanation:
To calculate the number of calls received per operator, you will first need to read values into the variables callsReceived and operatorsOnCall. You can do this using an input method appropriate for the programming language you're using (e.g., scanf in C, cin in C++, or input() in Python). Once you have these values, you perform the division of callsReceived by operatorsOnCall and print the result. Here is an example code snippet in Python:
# Read the number of calls received and the number of operators on callNote that integer division with truncation is used (// in Python) to get an integer result.
When askingfor a raise, which one among the following is important toremember?
a- Effort is to berewarded
b- Non-cash benefits may beof value if a raise is not feasible
c- The length of employmentis a great bargaining tool in asking for araise
d- Emotional appeals canhelp in getting a positive response to therequest
Answer:
a-Effort is to be rewarded
Explanation:
When you ask for a raise in an organization,the one of the most important thing is Effort.There is a reason for everything in organization,if you are asking to raise your income organization will ask you on which basis you are asking.If you put extra hours than before or you gain some skill which is useful for the organization,so while asking for raise you should know the effort that you put in because effort is most important factor for a raise.
In formal organizations, Non cash benefits are not there so there is no purpose for asking it.
Employment does not matter for the peer in asking for a raise,sometimes it is used by small organizations but it is informal,the one should focus more on effort rather than the employment.
Emotional appeals may help in informal organization,never in formal organization.It only imprints negative image on peer's mind,if you want to have a raise you should focus on Effort.
