Swapping Numbers

Swapping Number

 

class Swap

{

public static void main(String[] args)

{

int a=10,b=15,temp=0;

temp=a;

a=b;

b=temp;

System.out.println("The swapped value of a="+a+" b="+b);

}

}

Output:

 The swapped value of a=15 b=10

Swapping of two variables without using third variable

class Swap

{

public static void main(String[] args)

{

int a=10,b=15;

a=a*b;

b=a/b;

a=a/b;

System.out.println("The swapped values a="+a);

System.out.println(b);

}

}

                                                  (or)

class Swap

{

public static void main(String[] args)

{

int a=10,b=15;

a=a+b;

b=a-b;

a=a-b;

System.out.println("The swapped values a="+a);

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

}

}

Output:

    The swapped values a=15

     b=10
