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;
}
