In Java write a method called wordCount that accepts a String as its parameter and returns the number of words in the String. A word is a sequence of one or more nonspace characters (any character other than ' '). For example, the call wordCount("hello") should return 1, the call wordCount("how are you?") should return 3, the call wordCount(" this string has wide spaces ") should return 5, and the call wordCount(" ") should return 0.

Final answer:

Use the exit command with the value 8 to signal abnormal termination in a script. The exit status can be used by the calling script to determine further action.

Explanation:

When writing a script in many programming environments, particularly in Unix-based systems like Linux or in languages like Bash, you can use the exit command to terminate a script and return a value to the calling script. To signal an abnormal termination and return a value of 8, you would include the line exit 8 at the appropriate place in your script. This exit status can then be checked by the calling script to determine how to proceed. Exit statuses are a conventional way to communicate the outcome of a script where typically a zero value indicates success and any non-zero value indicates an error or abnormal termination.

Final answer:

A Java program will simulate the annual population changes of Mexico and the United States and output the populations each year until Mexico's population exceeds that of the United States. The provided code includes a growth rate calculation and displays results annually in a loop.

Explanation:

To predict when the population of Mexico will exceed that of the United States, we will create a simple Java application that calculates the populations annually based on the given growth rates. The population of Mexico starts at 114 million with an annual increase rate of 1.01%, whereas the United States starts with a population of 312 million and experiences an annual decrease of 0.15%. Using a loop, we can simulate each year's population change until Mexico's population exceeds the United States' population. The code will display the population of each country per year alongside the number of years it took for the population of Mexico to surpass that of the United States.

Here's a basic outline of the Java code:

public class Population {
   public static void main(String[] args) {
       double populationMexico = 114e6;
       double populationUSA = 312e6;
       int years = 0;
       while (populationMexico <= populationUSA) {
           // Calculate the new populations
           populationMexico *= 1.0101;
           populationUSA *= 0.9985;
           years++;
           // Output the current year's populations
           System.out.println("Year " + years + ":");
           System.out.println("Mexico: " + (int)populationMexico + " people");
           System.out.println("USA: " + (int)populationUSA + " people");
       }
       System.out.println("It took " + years + " years for the population of Mexico to exceed that of the United States.");
   }
}

This program is within the scope of the first six chapters of most introductory programming textbooks, as it uses basic Java syntax, arithmetic operations, loops, and conditional statements.

Final answer:

The kernel of an operating system manages resources and facilitates communication between hardware and software, provisioning hardware resources, and handling drivers for the underlying electronics.

Explanation:

The function of the kernel in an operating system is not to provide a user interface or to be an application for device configuration, but rather to serve as the core component of the operating system. Its primary role is to manage the system's resources and to facilitate communication between hardware and software. The kernel is responsible for provisioning hardware resources to meet software requirements by performing tasks such as memory management, process scheduling, and handling input/output operations.

In this context, the kernel acts as a bridge, making sure that various hardware components and the software applications that need to use them can work together efficiently. This includes managing hardware drivers which are the software components that know how to communicate with the underlying electronics of the computer. Moreover, many kernel operations require high levels of privilege on the system because they interact closely with the hardware.

System.out.println("if you read the section on");

System.out.print("''quotes.''");

Final answer:

The options to change the boot priority order being grayed out in BIOS/UEFI are most likely due to a lack of permissions, often because the BIOS is password-protected, or due to Secure Boot being enabled, which needs to be disabled to change boot settings.

Explanation:

If you find that the options to change the boot priority order in the BIOS/UEFI setup are grayed out and not available, the most likely problem is that you don't have the necessary permissions to make these changes. This can often be due to BIOS settings being locked with a password. To resolve this, you'll need to enter the correct BIOS password. If the system was set up by someone else or is part of a school or organization, you may need to contact the administrator or IT department to obtain the password or have them change the boot order for you.

Another reason the options could be grayed out is due to a feature called Secure Boot being enabled, which can prevent any changes to the boot priorities to secure the system from unauthorized access. If this is the case, you would need to disable Secure Boot first, but keep in mind that you should be aware of the implications to system security before making such changes.

Answer:

By definition, multiprocessing refers to the processing of multiple processes at the same time by multiple CPUs.

By definition, multiprogramming keeps programs in main memory at the same time and execute them concurrently utilizing a single CPU doing a context switch.

The first difference is that multiprocessing uses multiple CPUs and multiprogramming to utilize context switch to do concurrency in one CPU. Another difference is that multiprocessing is more expensive but more efficient than multiprogramming due that it allows parallel processing.

Answer: Looking into IP header, for a specific field, that identifies TCP as the transport protocol to be used.

Explanation:

In the IP Header, there is a field (of 8 bits wide) , called Protocol in the IPv4 version, and Next header in IPv6, that contains a hexadecimal number that identifies the transport protocol to be used.

For instance, if the segment should be passed to TCP, the Protocol Field must be filled with  0x06 = 00000110.

Final answer:

Host B's network layer checks the Protocol field in the IP header to determine which transport layer protocol (TCP or UDP) should receive the datagram. For TCP, the Protocol field contains the number 6, guiding the network layer to forward the payload to TCP.

Explanation:

When Host B receives an IP datagram, the network layer identifies which transport layer protocol should receive the payload by examining the Protocol field in the IP header. This field, also known as the Next Header field in IPv6, contains a number that represents the transport layer protocol used for the segment or datagram. In the case of TCP, this number is 6. Conversely, if the payload were to be passed to UDP, the number would be 17. The network layer uses this number to correctly forward the payload to the designated protocol, ensuring that the TCP segment is passed to the TCP layer and not to UDP or any other protocol.

Final answer:

Documenting a program involves clearly detailing instructions, operation details, and interfaces like APIs for users and developers. It is crucial for problem-solving and communication in program development.

Explanation:

​​Documenting a program means writing down in a prescribed manner the instructions for using the program, the way in which the program performs its tasks, and other items that users, other developers, and management might require. It involves creating clear and precise documentation that includes all aspects of the program's operation, ensuring that anyone who needs to understand or work with the program has the necessary information at their disposal.

This process is integral to problem-solving within the development cycle, enabling effective communication between the code and its users or fellow developers. Writing high-quality documentation is akin to establishing a contract, often referred to in technical terms as an Application Program Interface (API), which dictates how other applications or users can interact with the program's services.

Proper documentation can include a variety of components such as a comprehensive instruction manual, clear definitions and markup in the code to facilitate syntax highlighting, and organizing a set of instructions with informative titles, introduction, body, and conclusion sections. This ensures that both the program and its interfaces (APIs) are usable and understandable by those who need to work with them.

Answer:

String[] data2 = Arrays.copyOf(data, 4); is the statement which copies the data array to the data2 array in java 6 .

Explanation:

The Arrays.copyOf() function copies the data from first array to another array in java .We pass the two argument in this function  first argument is the name of first array and second the length of first array .

Following are the program in java  

import java.util.Arrays; // import package  

public class Main

{

public static void main(String[] args) // main function

{

String[] data = { "abc", "def", "ghi", "jkl" }; // string declaration

// printing the array data1

 System.out.println("before copy new array:");

 for (int k = 0; k < data.length; k++)  

     {

 System.out.println(data[k]);

 }

String[] data2 = Arrays.copyOf(data, 4);

 // printing the array data2

     System.out.println("after copy new array:");

     for (int k = 0; k < data2.length; k++)  

     {

        System.out.println(data2[k]);

     }}}

Output:

before copy new array:

abc

def

ghi

jkl

after copy new array:

abc

def

ghi

jkl

The statement that copies the data array to the data2 array in Java 6 and later: data2 = Arrays.copyOf(data, data.length);

Arrays.copyOf(data, data.length): This method creates a new array named data2 that's a complete copy of the data array. It takes two arguments:

   {

   // while loop

       while(num>0)

       {

           // print the digits

           System.out.println(num%10);

           num=num/10;

       }

   }

   //driver method

public static void main (String[] args) throws java.lang.Exception

{

   try{

    // scanner object to read input string

       Scanner s=new Scanner(System.in);

        // variable

       int num;

       System.out.print("please enter the number: ");

       //read the number

       num=s.nextInt();

       // validate the input, read a positive number only

       while(num<=0)

       {

           System.out.print("enter a positive number only:");

           num=s.nextInt();

       }

       System.out.println("digit of number are:");

       // call the function

      dig(num);

   }catch(Exception ex){

       return;}

}

}

Explanation:

Read a number from user and assign it to variable "num".Check if it is positive or not.If input is negative then ask user to again enter a positive number till user enter a positive number.Then call the function with input number. In this method it will find the digits of the number in the while loop using modulus "%" operator.

Output:

please enter the number: -345

enter a positive number only:1234

digit of number are:

The question involves writing a method to print out the digits of a positive integer using a while loop and modulus operator, demonstrated through a simple Java example.

The task is to write a method in a programming language that takes a positive integer input and prints out the digits of the number using a while loop and the modulus operator. Here's a simple example in Java:

public class DigitPrinter {
   public static void printDigits(int number) {
       while (number > 0) {
           int digit = number % 10; // Get the last digit
           System.out.println(digit);
           number = number / 10; // Remove the last digit
       }
   }

   public static void main(String[] args) {
       // Example usage
       printDigits(123);
   }
}

This method uses the modulus operator (modulus operator) to obtain the last digit of the number by calculating the remainder when the number is divided by 10. It then prints this digit, divides the number by 10 to remove the last digit, and repeats these steps with the while loop (while loop) until all digits have been printed in reverse order.

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

   // variables

   int x=5,y=2,z=9;

   int min;

   // find the smallest value and assign to min

   // if x is smallest

   if(x < y && x < z)

   // assign x to min

    min=x;

     // if y is smallest

else if(y < z)

 // assign y to min

    min=y;

// if z is smallest

else

 // assign z to min

    min=z;

// print the smallest

cout<<"smallest value is:"<<min<<endl;

return 0;

}

Explanation:

Declare and initialize variables x=5,y=2 and z=9.Then check if x is less than y and x is less than z, assign value of x to variable "min" .Else if value of y is less than value of z then smallest value is y, assign value of y to "min".Else z will be the smallest value, assign its value to "min".

Output:

smallest value is:2

Answer:

name.charAt(0);

Explanation:

Given: 'name' is a variable of type String that has been assigned a value.

To determine: an expression whose value is the first character of the value of name.

Let us assume nae is assigned the value "test". So our expression should return the first character , that is 't'.

In order to do this, we can use the charAt method of String object.

String name="test";

char c = name.charAt(0);

Here 0 corresponds to the index of the character we are interested in.

Answer:

b) Systems thinking

Explanation:

When answering multimple choices questions, it is important to rule out options which simply doest make sense to be the right answer. Let's discard the c) (collaboration) because the question never states anything related to teamwork, not even a small suggestion about cooperation. option d)  looks good but it is important to keep in mind that experemintations does not always consider the steps described on the questions. Experimentation can be performed without rigorous reasoned analysis, on the other hand, abstract reasoning and systems thinking do involve reasoned analysis to envision possible solutions.  Why choosing b) and not a) then? This is because abstract reasoning, as the same concept states, it i focused on analysis and interpretations of problems and other  cases like understanding the behaviour of natural phenomena for example, while it is not necesaryly linked to implmenting solutions based on a certain set of resources, while, on the other hand, systems thiking does take them into account. Systems thinking is the complete process of  evaluation, proposition of solutions and execution from the idea to reality in a sensible way.  

The problem is b) She forgot to apply thermal paste between the CPU and the heat-sink and fan assembly

Thermal paste is important  to make sure the CPU and heat sink can transfer heat correctly. If the CPU doesn't have thermal paste, it can get too hot and make the computer stop working properly, even if it has power.

The LED on the motherboard shows that the power supply is working, but the problem is probably because the system is getting too hot and shutting down to protect itself.
