Code it warning about
PlayPause.java
public int getState(int actualstate) {
if(actualstate == PLAY_STATE){
krayaprocess.stopButton.setVisible(false);
krayaprocess.startButton.setVisible(true);
}else{
krayaprocess.stopButton.setVisible(true);
krayaprocess.startButton.setVisible(false);
}
}
Events.java
if (sel == "Exit") {
System.exit(1);
}
else if (sel == "Hierrarchy") {
TreeMap hierMenu = new TreeMap();
hierMenu.setVisible(true);
}
else if (sel=="Play"){
stopwatch.start();
playpause.STATE=1;
playpause.getState(1);
}
else if (sel =="Stop") {
stopwatch.stop();
playpause.STATE=0;
stopwatch.reset();
playpause.getState(0);
}
else if (sel=="About") {
