import javax.swing.*;    public class hangmanpanel extends jpanel {     private static final long serialversionuid = -5793357804828609325l;      public hangmanpanel(){          jlabel heading = new jlabel("welcome hangman app");         jbutton button = new jbutton("ok");         //button.addactionlistener();            jlabel tflable = new jlabel("please enter letter");         jtextfield text = new jtextfield(10);          string input = text.gettext();         heading.setlocation(50, 20);         tflable.setlocation(20, 100);         text.setlocation(320, 50);         button.setlocation(230, 100);          this.add(heading);         this.add(tflable);         this.add(text);         this.add(button);     } }

you should not use setlocation() layout swing components, better use layout. please have @ these layout tutorials.
