RSNameChecker

Decided to create it a month ago when everyone was making one, never tried to sell because it wasn't stable enough but for anyone wanting to know how to do it here's my Thread :

            } else {

            }
            MainGUI.amtNamesChecked++;
            MainGUI.statsLbl.setText("Checked " + MainGUI.amtNamesChecked + "/" + MainGUI.totalAmtNames);
            if (MainGUI.amtNamesChecked >= MainGUI.totalAmtNames) {
                MainGUI.running = false;
                System.out.println(System.currentTimeMillis() - time);
                MainGUI.saveAvalibleNames(MainGUI.outputFilePath);

            }
        }

    }
}

 

Are you new to Java? Why are you extending thread?

 

Because it's my thread object and I see no reason to implement runnable instead in this circumstance.
