java - thread doesn't execute -
i'm new in java, guess it's simple problem. in event listener have method declares variables , i'm trying use variables in thread use in same event. although not work, here code:
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class gui extends frame implements windowlistener,actionlistener { cpwindow window1 = new cpwindow(); cmwindow window2 = new cmwindow();

f0.add(cp); f0.add(cm); f0.add(delete); cp.addactionlistener(this); cm.addactionlistener(this); delete.addactionlistener(this); cp.setactioncommand("1"); cm.setactioncommand("2"); delete.setactioncommand("3");

one needs start thread, instantiating thread object not enough.
public void actionperformed(actionevent e) { createvariables(); new newthread().start(); }
