Recursive Constructor Invocation

Question

public class LecturerInfo extends StaffInfo {

    private float salary;

    public LecturerInfo()
    {
        this();
        this.Name = null;
        this.Addr         


        

Answer 1

the code below is recursive. Since this() will call no arg constructor of current class that means LectureInfo() again.

public LecturerInfo()
{
    this(); //here it translates to LectureInfo() 
    this.Name = null;
    this.Address = null;
    this.salary=(float) 0.0;
}

Answer 2

if you modify the fist constructor to this:

 public LecturerInfo()
 {
   this(null, null, (float)0.0);
 }

this will be recursive.

Answer 3

by calling this() you are calling your own constructor. By observing your code it seems you were supposed to call super() instead of this();
