Cycle problems while java

I need your help. Something strange happens in this part of the code. abc = is a created object that handles the graphical interface and the tcp connection. up there all right the abc object creates the graphical interface and manages the tcp connection. the interface has a connection button that when pressed creates the socket and establishes the connection with the server.

Inside the while this System.out.println (); which does not do anything is put there because if it is not it does not enter the if cycle when the connection is established. someone can explain this to me. Why does it work this way? Any way to improve it or solve it? package gui;
