        int a=10, b=20, temp;
        System.out.println("Before swapping");
        System.out.println("value of a="+a);
        System.out.println("value of b="+b);
        temp=a;
        a=b;
        b=temp;
        System.out.println("After swapping");
        System.out.println("value of a="+a);
        System.out.println("value of b="+b);
