/** * * @author compaq */public class DemoVariabel { public static void main(String[] args) { //contoh bilangan bulat/integer byte aByte =120; short aShort = 255; int anInteger = 4500; long aLong = 56789l; //contoh bilangan real float aFloat = 87.36f; double aDouble = 87.363D; //tipe primitif lainnya char aChar = 'S'; boolean aBoolean = true; System.out.println("aByte berisi"+aByte); System.out.println("aShort berisi"+aShort); System.out.println("anInteger berisi"+anInteger ); System.out.println("aLong berisi"+aLong); System.out.println("aFloat berisi" +aFloat); System.out.println("aDouble berisi"+aDouble); System.out.println("aChar berisi"+aChar); System.out.println("aBoolean berisi"+aBoolean); } }
Maka hasilnya akan seperti ini :

Maka hasilnya akan seperti ini :
anInteger=anInteger setelah anInteger = anInteger/4 adalah 100Setelah operasi x =anInteger++maka nilai untuk anInteger=101dan x=100Setelah operasi x=++anInteger maka nilai untukanInteger=102dan x=BUILD SUCCESSFUL (total time: 0 seconds)
