Why does while(true) loop just run once - Java

I read serveral similar questions but those answers couldnt help me with my problem: This is a while(true) loop for a tictactoe game and should run the whole time. But it only runs once I tested it EXCEPT I type a sysout somewhere in the loop...(not in one of the if statements): Doesn't work like this: void winCheck() { while(true) { if(buttons[0].getValue() == 1 && buttons[1].getValue() == 1 && buttons[2].getValue() == 1) { dispose(); JOptionPane.showMessageDialog(null, "Crosses win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[3].getValue() == 1 && buttons[4].getValue() == 1&& buttons[5].getValue() == 1) { dispose(); JOptionPane.showMessageDialog(null, "Crosses win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[6].getValue() == 1 && buttons[7].getValue() == 1 && buttons[8].getValue() == 1) { dispose(); JOptionPane.showMessageDialog(null, "Crosses win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[0].getValue() == 1 && buttons[3].getValue() == 1 && buttons[6].getValue() == 1 ) { dispose(); JOptionPane.showMessageDialog(null, "Crosses win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[1].getValue() == 1 && buttons[4].getValue() == 1 && buttons[7].getValue() == 1) { dispose(); JOptionPane.showMessageDialog(null, "Crosses win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[2].getValue() == 1 && buttons[5].getValue() == 1 && buttons[8].getValue() == 1 ) { dispose(); JOptionPane.showMessageDialog(null, "Crosses win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[0].getValue() == 1 && buttons[4].getValue() == 1 && buttons[8].getValue() == 1) { dispose(); JOptionPane.showMessageDialog(null, "Crosses win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[6].getValue() == 1 && buttons[4].getValue() == 1 && buttons[2].getValue() == 1 ) { dispose(); JOptionPane.showMessageDialog(null, "Crosses win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[0].getValue() == 2 && buttons[1].getValue() == 2 && buttons[2].getValue() == 2) { dispose(); JOptionPane.showMessageDialog(null, "Noughts win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[3].getValue() == 2 && buttons[4].getValue() == 2 && buttons[5].getValue() ==2 ) { dispose(); JOptionPane.showMessageDialog(null, "Noughts win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[6].getValue() ==2 && buttons[7].getValue() == 2 && buttons[8].getValue() == 2) { dispose(); JOptionPane.showMessageDialog(null, "Noughts win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[0].getValue() == 2 && buttons[3].getValue() == 2 && buttons[6].getValue() == 2 ) { dispose(); JOptionPane.showMessageDialog(null, "Noughts win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[1].getValue() == 2 && buttons[4].getValue() == 2 && buttons[7].getValue() == 2 ) { dispose(); JOptionPane.showMessageDialog(null, "Noughts win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[2].getValue() == 2 && buttons[5].getValue() == 2 && buttons[8].getValue() == 2 ) { dispose(); JOptionPane.showMessageDialog(null, "Noughts win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[0].getValue() == 2 && buttons[4].getValue() == 2 && buttons[8].getValue() == 2 ) { dispose(); JOptionPane.showMessageDialog(null, "Noughts win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[6].getValue() == 2 && buttons[4].getValue() == 2 && buttons[2].getValue() == 2) { dispose(); JOptionPane.showMessageDialog(null, "Noughts win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if( (buttons[0].getValue() == 1 || buttons[0].getValue() == 2) && (buttons[1].getValue() == 1 || buttons[1].getValue() == 2) && (buttons[2].getValue() == 1 || buttons[2].getValue() == 2) && (buttons[3].getValue() == 1 || buttons[3].getValue() == 2) && (buttons[4].getValue() == 1 || buttons[4].getValue() == 2) && (buttons[5].getValue() == 1 || buttons[5].getValue() == 2) && (buttons[6].getValue() == 1 || buttons[6].getValue() == 2) && (buttons[7].getValue() == 1 || buttons[7].getValue() == 2) && (buttons[8].getValue() == 1 || buttons[8].getValue() == 2)) { dispose(); JOptionPane.showMessageDialog(null, "Draw..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } } } but it works like this (sysout at the end) so it runs the whole time not just once: void winCheck() { while(true) { if(buttons[0].getValue() == 1 && buttons[1].getValue() == 1 && buttons[2].getValue() == 1) { dispose(); JOptionPane.showMessageDialog(null, "Crosses win..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } else if(buttons[3].getValue() == 1 && buttons[4].getValue() == 1&& buttons[5].getValue() == 1) { dispose();

JOptionPane.showMessageDialog(null, "Draw..", "TicTacToe", JOptionPane.INFORMATION_MESSAGE); Start.main(null); } System.out.println(); } } I just don't get why :/ Tried many things but didn't work.. Answer would be so cool.. by the way even stranger: It works without System.out.println() in debug mode but not in normal mode or exported as jar...
