Demo Code

class MyClass extends MyBase {
    public MyClass() {
        super();  // Injected by the compiler 
        System.out.println("Inside CSub() constructor.");
    }/*w ww  .  j a v  a2  s.c  om*/
}
class MyBase {
    public MyBase() {
        super();  // Injected by the compiler 
        System.out.println("Inside CSuper() constructor.");
    }
}


public class Main {
  public static void main(String[] args) {
    MyClass cs = new MyClass();
  }
}
