Can constructor be public, private, protected

Question

?

Answer 1

class classname{

public classname(){ // these constructor must public
} // same with the class name
// it will executed once during first load
// during classname a = new classname();
}

Answer 2

I wouldn't recommend making it private as it needs to be called from outside the class.

Answer 3

The only way I can think a private constructor could be used is
Class a{
private a() {
}
Public static void main(String[] args) {
New a();
}

}
