What does “this()” method mean?

Question

I ran into this block of code, and there is this one line I don\'t quit understand the meaning or what it is doing.

public Digraph(In in) {
    this(in.readI         


        

Answer 1

Calling this essentially calls the class Constructor. For example, if you're extending something, than along with add(JComponent), you could do: this.add(JComponent).
