Cast after cloning : Clone « Class Definition « Java Tutorial






class A {
  int l = 1;
}

class B extends A implements Cloneable {
  int m = 2;
}

class CloneDemo3 extends B {
  int n = 3;
  A a = new A();

  public static void main(String[] args) throws CloneNotSupportedException {
    CloneDemo3 c = new CloneDemo3();
    CloneDemo3 c2 = (CloneDemo3) c.clone();

    System.out.println(c.l);
    System.out.println(c2.l);
    System.out.println(c.m);
    System.out.println(c2.m);
    System.out.println(c.n);
    System.out.println(c2.n);

    System.out.println(c.a == c2.a);
  }
}
