Constructor question.

[Sanjeev Ba]

abstract class Maker{
	String member;
	
	Maker(String s){
		member = s;
		System.out.println("Assigned in abstract class");
	}
}

public class Constructor extends Maker{
	public static void main(String[] args) {
		Constructor c = new Constructor("test");
	}
	
	Constructor(String s)
	{
		super(s);
		System.out.println(member);
	}
	
	protected Constructor(int i){
		super("test");
	}
	public Constructor(){
		super("test");
	}
	private Constructor(float f){
		super("test");
	}
}

While the above code is legal and valid can someone tell me the point of allowing this sort of design i.e. allowing multiple constructors with different access permissions for making one type of object.

We have to look it in this way, who(scope) are gonna instantiate my class and what type of instantiation mechanism I should allow them.

In above case:

protected Constructor(int i)----------> Can be available for all class's with in this package and sub classes
public Constructor()------------------->Any one can use this
private Constructor(float f)----------------> no body gonna use, except with in this class.
