java - Why isn't my program using the variables? -

i trying make object orientated javafx program have encountered problem can't seem fix, window variables set , when print them console set when come use them in start method doesn't seem acknowledge there.

main class:

import com.mersey.ui.window;  public class main  {     public static void main(string[] args)      {         window win = new window();          win.create("mersey", 980, 640, false);         window.launch(window.class, args);     } } 

window class:

package com.mersey.ui;  import javafx.application.application; import javafx.scene.scene; import javafx.scene.layout.pane; import javafx.stage.stage;  public class window extends application {     protected stage   windowstage;     protected pane    windowroot;     protected scene   windowscene;     protected string  windowtitle;     protected int     windowwidth;     protected int     windowheight;     protected boolean windowresizable;      public void create(string title, int width, int height, boolean resizable)     {         windowtitle     = title;         windowwidth     = width;         windowheight    = height;         windowresizable = resizable;          /*         system.out.print(windowtitle+"\n");         system.out.print(windowwidth+"\n");         system.out.print(windowheight+"\n");         system.out.print(windowresizable);*/     }      @override     public void start(stage stage) throws exception      {         windowstage = stage;         windowroot  = new pane();         windowscene = new scene(windowroot, windowwidth, windowheight);         windowstage.setscene(windowscene);          windowstage.settitle(windowtitle);         windowstage.setwidth(windowwidth);         windowstage.setheight(windowheight);         windowstage.setminwidth(windowwidth);         windowstage.setminheight(windowheight);         windowstage.setresizable(windowresizable);          windowstage.show();     } } 

i think* youre going want here, not construct window object call window.launch in way now, instead, funnel values width height , via string[] args passed window.launch. documentation says can retreive values via getparameters(), this:

//in main string[] launchargs = new string[] {"width=800", "height=600"}; window.launch(window.class, launchargs);  ..........................   //in start(stage)  string[] args = getparameters(); (string s : args) {      if (s.contains("width")) {         //parse , set window width here      } } 

see this: http://docs.oracle.com/javafx/2/api/javafx/application/application.html#launch(java.lang.class, java.lang.string...)

of course, assumes want able supply arbitrary values class fields within main. if not, hard code default value, or pull them config in start(stage) method.
