Question

Add a second data member (another int) to the class ObjX. Then in main assign a value to the new variable and print it.

class ObjX {

    // No "static" keyword for either member.

    int i;

    void print ()
    {
        System.out.println ("i=" + i);
    }

}


public class DynamicExample {

    public static void main (String[] argv)
    {
        // First create an instance, which allocates space from the heap.
        ObjX x = new ObjX (); 

        // Now access members via the variable and the dot-operator.
        x.i = 5;
        x.print();
    }

}

Answer 1

class ObjX {

  // No "static" keyword for either member.
  int j;
  int i;

  void print ()
  {
    System.out.println ("i=" + i);
  }

}

public class DynamicExample {

    public static void main (String[] argv)
    {
        // First create an instance, which allocates space from the heap.
        ObjX x = new ObjX ();

        // Now access members via the variable and the dot-operator.
        x.j = 5;
        System.out.println(x.j);
    }

}
