Using parent constructor in a child class in Java

Question

I have a class \"ChildClass\" that extends the class \"ParentClass\". Rather than completely replace the constructor for the parent class, I want to call the parent class\'s

Answer 1

You can reference the parent's constructor with "super", from within a child's constructor.

public class Child extends Parent {
    public Child(int someArg) {
        super(someArg);
        // other stuff
    }
    // ....
}

Answer 2

To invoke a specific parent-class constructor, put super(param1, param2, ...) as the first statement in the child-class constructor body.

Answer 3

You should use the super keyword.

public ChildClass(...) {
    super(...);
}
