Class 10

Write a function that interchanges the value of two integers A and B without using any extra variable.

Answer 1

import java.util.*;

class exchange

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.println("enter 2 integers");

int a=sc.nextInt();

int b=sc.nextInt();

int i;

for(i=a;i is less than equal to a;I++)

{

b=a;

i=b;

}

System.out.println(a);

System.out.println(b);

}

}

I can't find the symbol of less than so

Answer 2

Answer:

class prog{

void main(int a,int b)

{

a=a+b;

b=a-b;

a=a-b;

System.out.println(a+" "+b);

}

}

i haven't used any extra variable like the other who has answered.

please mark it as the brainliest answer.
