Question

The value of a is 34 and the value of b is 79. Write a JAVA program to interchange the value of a and b. display the variables before interchange and after interchange. Ex:
Before interchange a=34 b= 79
After interchange a=79 b=34​ DO NOT USE ANY INPUT METHOD​

Answer 1

Answer:

Program:-

import java.util.*;

public class Main

{

public static void main(String args[])

{

Scanner in=new Scanner(System.in);

int a=34,b=79;

System.out.println("Before interchange a="+a+" b="+b);

System.out.println("After interchange a="+b+" b="+a);

in.close();

}

}

• The logic is simple just interchange the values of a and b and print b in place of a and and a in place of b.
