How do I augment the constructor of a child class?

Question

I have a class that extends another class. I need to run additional code in the constructor of my child class. How do I do this?

//MyClass.class
//This is what i want to do
public class MyClass extends BaseClass {
    constructor() {
        super(); // EDIT (thanks)
        // stuff?
    }
}

Please help.

First of all, it's `super()`. – Mohammed Aouf Zouag Jan 08 '16 at 22:12 — Mohammed Aouf Zouag, Jan 08 '16 at 22:12

should be:

/MyClass.class
//This is what i want to do
public class MyClass extends BaseClass {
    MyClass() {
        super(); // no need for constructor here, just super()
        // stuff?
    }
}

Simply call super(). This will call the super class's constructor. See Can an abstract class have a constructor?

How do I add to the constructor? – dopatraman Jan 08 '16 at 22:26
Just add the new code in place of the `// stuff` line. – FredK Jan 08 '16 at 22:46
