call one constructor from another constructors in one class

Question

I've encountered the following question online.

If we call one constructor from another in a class, what will happen?

Can anyone give me some hints?

Answer 1

in java also its possible with the power of the this keyword. check out the example given below.

public class A {

    public A() {
        //this("a");
        System.out.println("inside default Constructor");
    }

    public A(String a){
        this();
        System.out.println("inside Constructor A");
    }

}

This concept is called constructor chaining. If it's c# i found this saying it's possible Is nesting constructors (or factory methods) good, or should each do all init work
