Swapping Variables.

Using a Temp Variable.

import java.util.*;
import java.util.Scanner;

public class Main
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
     
System.out.println("Enter the Nums");
int a=input.nextInt();
int b=input.nextInt();
System.out.println("Initial Value of a is"+a);
System.out.println("Initial Value of b is"+b);
int Temp=a;
a=b;
b=Temp;
System.out.println("Final Value of a is"+a);
System.out.println("Final Value of b is"+b);

}
}


Without using a Temp Variable.


import java.util.*;
import java.util.Scanner;

public class Main
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);

System.out.println("Enter the Nums");
int a=input.nextInt();
int b=input.nextInt();
System.out.println("Initial Value of a is"+a);
System.out.println("Initial Value of b is"+b);
a=a+b;
b=a-b;
a=a-b;
System.out.println("Final Value of a is"+a);
System.out.println("Final Value of b is"+b);

}

}
