baherus [9]

<u>Answer:</u>

//import the necessary class

import java.util.Scanner;

//Begin class definition

public class ConvertToCelsius{

   

       //Begin main method

    public static void main(String []args){

       //Create an object of the Scanner class

       Scanner input = new Scanner(System.in);

       

       //Display the aim of the program

       System.out.println("**Program to convert from Fahrenheit to Celsius**");

       

       //Prompt the user to enter the temperature in Fahrenheit

       System.out.println("Please enter temperature in Fahrenheit");

       

       //Receive the user's input

       //And store in the appropriate variable

       double tempF = input.nextDouble();

       

       //Convert the temperature to Celsius using

       //C = (9.0 / 5) * (F - 32)

       //C = temperature in Celsius, F = temperature in Fahrenheit

       double tempC = (9.0 / 5) * (tempF - 32);

       

       //Display the result

      System.out.println("The temperature in degree Celsius is: ");

       System.out.println(tempC);

       

       return;

       

    }    //End of main method

}    //End of class definition

<u>Sample Output</u>

**Program to convert from Fahrenheit to Celsius **

Please enter temperature in Fahrenheit

>> 32

The temperature in degree Celsius is:  

0.0

<u>Explanation</u>:

The above code has been written in Java and it contains comments explaining important lines of the code. Please go through the comment. Snapshots of the program and a sample output have been attached to this response.

Define a method named swapValues that takes an array of four integers as a parameter, swaps array elements at indices 0 and 1, a
Luba_88 [7]

The program is an illustration of arrays.

Arrays are used to hold multiple values.

The program in java, where comments are used to explain each line is as follows:

import java.util.*;

public class Main{

   //This defines the method

public static int[] swapValues(int[] arr) {

   //This swaps the first and second array elements

       int temp = arr[0];

       arr[0] = arr[1];   arr[1] = temp;

   //This swaps the third and fourth array elements

       temp = arr[2];

       arr[2] = arr[3];   arr[3] = temp;

   //This returns the swapped array to main

       return arr;

}

//The main method begins here

   public static void main(String[] args) {

       //This creates a Scanner object

       Scanner input = new Scanner(System.in);

 //This declares an array of 4 elements

 int[] intArray = new int[4];

 //This gets input for the array

 for(int i = 0; i<4;i++){

     intArray[i] = input.nextInt();

 }

 //This calls the swapValues method

 intArray=swapValues(intArray);

 //This prints the swapped array

 for (int i = 0; i < 4; i++){

 System.out.print( intArray[i]+ " ");     }

}  

}

At the end of the program, the elements are swapped and printed.
