public class MainClass {

  public static void main(String args[]) {

    Integer intObject, intObject2;

    int i;



    intObject = 100;

    System.out.println("Original value of iOb: " + intObject);



    ++intObject;

    System.out.println("After ++iOb: " + intObject);



    intObject2 = intObject + (intObject / 3);

    System.out.println("iOb2 after expression: " + intObject2);



    i = intObject + (intObject / 3);

    System.out.println("i after expression: " + i);



  }

}

Original value of iOb: 100
After ++iOb: 101
iOb2 after expression: 134
i after expression: 134
