Question

If I have a class

class Foo{
    String name;
    public Foo(String s){
        name=s;
    }

    public void setName(String s){
        name=s;
    }

    public String getName(){
        return name;
    }
}

and then

class FooBar extends Foo {
    public FooBar(String S){
        super(s);
    }
}

and my main method is

public static void main(String[] args){
    FooBar item1 = new FooBar("Jim");
}

Will the super() call in class FooBar then call the constructor for Foo() and properly set the name to s? Is this what a plain super() call does? Call the constructor of the class being extended?

Answer 1

Yes, that is exactly what it does. It calls the constructor for the super / base class.
