im trying add image jlabel , have encountered problem image big jlabel i'm looking way make image automatically scale size of jlabel.

here main body of code call guimain class:

public class main  {     public static void main(string[] args)     {         int = 0;         int t = 0;         int st = 0;         int h = 0;          texts textobject = new texts();         textobject.textlist();          commands commandobject = new commands();         commandobject.commands();          guimain guiobject = new guimain();         guiobject.displaygui();     } } 

and here code guimain class, include 1 image button because there allot of objects in code.

import java.awt.eventqueue; import java.awt.graphics; import java.awt.image; import java.awt.image.bufferedimage;  import javax.swing.imageicon; import javax.swing.jframe; import javax.swing.jbutton; import javax.swing.jlist; import javax.swing.jtextpane; import javax.swing.jlabel; import javax.swing.jtextarea; import javax.swing.jscrollbar; import javax.swing.jtextfield; import javax.swing.jpanel; import javax.swing.border.titledborder;      public class guimain      {         private jframe frame;         private jtextfield textfield;         private imageicon image1;      public void displaygui()      {         this.frame.setvisible(true);     }      //launch application.     public static void main(string[] args)     {         guimain window = new guimain();     }      //create application.     public guimain()          {         frame = new jframe();         frame.setbounds(100, 100, 611, 471);         frame.setdefaultcloseoperation(jframe.exit_on_close);         frame.getcontentpane().setlayout(null);          ...          jlabel lblhunger = new jlabel();         image img2 = new imageicon(this.getclass().getresource("/food.png")).getimage();         lblhunger.seticon(new imageicon(img2));         lblhunger.setbounds(211, 58, 50, 50);         panel.add(lblhunger);         }     } } 

don't use null layout!!!

swing designed used layout managers. let each component determine preferred size , let layout manager size , position component based on rules of layout manager.

instead of doing custom painting can use darry'ls stretch icon. icon painted based on space available icon.

i have encountered problem image big jlabel

just reread part of question. in case may want use image.getscaledinstance(...) method scale image appropriate size. can use regular icon , appropriate layout manager.

what layout able use choose dimensions , objects positioned

you not supposed choose size/location of component. job of layout manager. read tutorial on layout managers , choose 1 (or combination of layout managers) appropriate requirements.
