java - using a predefined String in a GUI -

i have gui set way want i'm trying output string called answerkey have predefined in dashreplace() tried draw string , use jlabel can't seem find right method of doing such.

import java.awt.*; import java.awt.event.actionlistener; import java.util.arraylist; import java.util.arrays; import java.util.collections;  import javax.swing.*;    public class hangmanpanel extends jpanel {     private static final long serialversionuid = -5793357804828609325l;      public static string answerkey() {         //get random array element         string array[] = new string[10];         array[0] = "hamlet";         array[1] = "mysts of avalon";         array[2] = "the iliad";         array[3] = "tales edger allan poe";         array[4] = "the children of hurin";         array[5] = "the red badge of courage";         array[6] = "of mice , men";         array[7] =  "utopia";          array[8] =  "chariots of gods";         array[9] =  "a brief history of time";          arraylist<string> list = new arraylist<string>(arrays.aslist(array));         collections.shuffle(list);         string s = list.get(0);         return s;     }      public static stringbuilder dashreplace(string s) {         //replace non-white space char dashes , creates stringbuilder object         string tw = s.replaceall("\\s", "-");          system.out.print(tw + "\n");           stringbuilder answerkey = new stringbuilder(tw);         return answerkey;     }         public hangmanpanel(){         this.setlayout(null);          jlabel heading = new jlabel("welcome hangman app");         jbutton button = new jbutton("ok");         //button.addactionlistener((actionlistener) this);           jlabel tflable = new jlabel("please enter letter:");          //trying out put predefined string         jlabel answerkey = new jlabel(answerkey);          jtextfield text = new jtextfield(10);         //string input = text.gettext();          heading.setsize(200, 50);         tflable.setsize(150, 50);         text.setsize(50, 30);         button.setsize(60, 20);          heading.setlocation(300, 10);         tflable.setlocation(50, 40);         text.setlocation(50, 80);         button.setlocation(100, 85);          this.add(heading);         this.add(tflable);         this.add(text);         this.add(button);     }  } 

the method called answerkey, not answerkey. in fact, surely won't compile you've written - you're trying assign variable while using variable constructor parameter. should be:

jlabel answerkey = new jlabel(dashreplace(answerkey()).tostring()); 

to make work, however, you'll need make method non-static. also, having variable named answerkey , method named answerkey crying out confusion - i'd suggest better name jlabel.
