public Static void main (String arg [])
{
int x = 17, y = 5;
System.out.println ("x =" + x); // x = 17
System.out.println ("y =" + y); // y = 5
System.out.println ("x + y =" (x + y));
System.out.println ("xy =" (xy));
System.out.println ("x * y =" (x * y));
System.out.println "x / y =" (x / y));
}
}
