java - How to name JFrame in a constructor -

question may different expected, i'm creating utility function jframes make easier future me.

public void setjframe(string title, int w,int h, jframe name, boolean maximize){     name.setsize(w, h);     name.settitle(title);      if (maximize == true) {         name.setextendedstate(name.getextendedstate()|jframe.maximized_both);     } else {         name.setlocationrelativeto(null);     } } 

i want ability name jframe type in parameters. @ moment, when type in string spits out error saying can't use string? want "name" string variable can type in string value , have object named that.

edit: need make question more clear...

packagename.setjframe("title of frame", 500, 800, f, false); 

returns error:

exception in thread "main" java.lang.error: unresolved compilation problems:

f cannot resolved

f cannot resolved

at gui.guimain.guiset(guimain.java:17)

at urapackage.main.main(main.java:8)

eclipse says method f not applicable constructor

using method, setjframe, need pass instantiated new jframe forth parameter such:

import java.awt.eventqueue; import javax.swing.jframe;  public class createjframe {      public static void main(string[] args) {         eventqueue.invokelater(new runnable() {             public void run() {                 try {                     jframe frame1 = new jframe();                     setjframe("title of first frame", 500, 800, frame1, false);                     frame1.setvisible(true);                      jframe frame2 = new jframe();                     setjframe("title of second frame", 100, 200, frame2, false);                     frame2.setvisible(true);                      jframe frame3 = new jframe();                     setjframe("title of third frame", 100, 200, frame3, true);                     frame3.setvisible(true);                 } catch (exception e) {                     e.printstacktrace();                 }             }         });     }      public static void setjframe(string title, int w, int h, jframe name, boolean maximize) {         name.setsize(w, h);         name.settitle(title);          if (maximize == true) {             name.setextendedstate(name.getextendedstate() | jframe.maximized_both);         } else {             name.setlocationrelativeto(null);         }     } } 

if want forth parameter string, either extend jframe , specify additional constructor(s) accept string, or can create method whereby jframe object returned.

edit: unless of course, meant naming internal variable name. functionality not possible during runtime. can't imagine use such function anyways. above paragraph assumes mean setting name of jframe (via setname()).
