Answer 2

You can use it so you'll only need to write a specific code once in one constructor, so you dont need to write it again. Or also you can use them to create object with default value client doesnt pass the parameters.

For example you decide to extends a JFrame class. There's no way we know how the jframe are initiated. But with chaining we can call the constructor from JFrame to run as ours by calling super() we can also add additional code after call super(). here's an example
