/* in class SwapTester (cont’d) . . . */

public static void main (String argv[]) {

int x, y, z; x = 5; y = 10; z = y; y = 5;

System.out.println ("x=" + x + " y=" + y + " z=" + z);

System.out.println ("x==5 is " + (x==5));

System.out.println ("x==y is " + (x==y));

System.out.println ("y==z is " + (y==z));

swapInt (x, z);

System.out.println ("x=" + x + " y=" + y + " z=" + z);

System.out.println ();

Output for this portion of the program:

x=5 y=5 z=10

x==5 is true

x==y is true

y==z is false

Doing swapInt

x=5 y=5 z=10
