import javax.swing.*;  import java.awt.*;  /*  * 2 labels withdraw/deposit. * 2 textfields entering withdrawal/deposit amount. * 1 label balance, 1 non-editable textfield balance. * event listener on calculate button. * action performed: balance minors withdrawal plus deposit */  / ** * class manages input numbers. user input withdrawal/deposit amount * , program display balacne after transfers. * @author administrator * */  public class datapanel extends jpanel {  public final int textfield_length = 10; public final int layout_vgap = 25; public final int layout_hgap = 15;   /**  * constructor sets layout, creates labels/fields.  */  public jpanel pane1 = new jpanel(); public jpanel pane2 = new jpanel(); public jpanel pane = new jpanel(new gridlayout(1,2));      //create necessary fields , labels     jlabel withdrawallabel = new jlabel("withdrawal: ");     jlabel depositlabel = new jlabel("deposit: ");     jtextfield withdrawaltext = new jtextfield(textfield_length);     jtextfield deposittext = new jtextfield(textfield_length);      jlabel balancelabel = new jlabel("balance: ");     jtextfield balancetextfield = new jtextfield(textfield_length);      jlabel totalsavinglabel = new jlabel("recently saved: ");     jtextfield totalsavingtextfield = new jtextfield(textfield_length);      jlabel totalspentlabel = new jlabel("recently spent: ");     jtextfield totalspenttextfield = new jtextfield(textfield_length);      //set textfields non editable.       //set layout, 3 rows + 2 columns.      public datapanel()     {            setlayout(new gridlayout(2,1));          buildpane1();          buildpane2();          buildpane();          add(pane);       //add components panel datapanel.  }      public void buildpane()     {         pane.add(pane1);         pane.add(pane2);     }      public void buildpane1()     {         setlayout(new gridlayout(3,2));          setborder(borderfactory.createlineborder(color.pink, 2, true));          balancetextfield.seteditable(false);              pane1.add(withdrawallabel);         pane1.add(withdrawaltext);         pane1.add(depositlabel);         pane1.add(deposittext);         pane1.add(balancelabel);         pane1.add(balancetextfield);     }      public void buildpane2()     {         setlayout(new gridlayout(2,2));          setborder(borderfactory.createlineborder(color.black, 2, true));          totalsavingtextfield.seteditable(false);         totalspenttextfield.seteditable(false);          pane2.add(totalsavinglabel);         pane2.add(totalsavingtextfield);         pane2.add(totalspentlabel);         pane2.add(totalspenttextfield);      } } 

jframe class:

import java.awt.borderlayout; import java.awt.gridlayout;  import javax.swing.jframe; import javax.swing.jpanel; import javax.swing.jtabbedpane;   public class mainframe extends jframe { public final int width = 1000; public final int height = 800;  public datapanel datapane; public infopanel infopane; public menu menu;  public jtabbedpane tabbedpane = new jtabbedpane();  //tab #1 public jpanel spendingpane;  //tab #2 public jpanel personalpane;  //tab #3 public jpanel socialpane;  //tab #4 public jpanel chatpane;    /**  * constructor.   */ public mainframe() {     settitle("personal banking");     setsize(width, height);     setlayout(new borderlayout());      buildmenu();     buildpanel();      add(tabbedpane);      pack();     setvisible(true); }  /**  * methods builds components.  */  private void buildpanel() {     //build main panel (spending  panel).     datapane = new datapanel();        //add numbers panel tabbed panel.     tabbedpane.addtab("numbers", datapane);      //build personal information panel.     infopane = new infopanel();     personalpane = new jpanel();     personalpane.add(infopane);      //add personal information panel tabbed panel.     tabbedpane.addtab("personal", personalpane);   }  /**  * function builds menu bar , menu items.  */ private void buildmenu() {     menu = new menu();     setjmenubar(menu.mainmenubar); }    public static void main(string args[]) {     new mainframe(); } } 

i have tried several methods, didn't work.

***well apparently pasted first class twice. fixed it. sorry that.

based on example (and little change background color of each pane), can see been added

however, this...

public void buildpane1() {     setlayout(new gridlayout(3,2));      setborder(borderfactory.createlineborder(color.pink, 2, true)); 

and this...

public void buildpane2() {     setlayout(new gridlayout(2,2));      setborder(borderfactory.createlineborder(color.black, 2, true)); 

look suspicious, been applied datapanel , not (as suspect want) individual panels...

so changing them more like...

public void buildpane1() {      pane1.setlayout(new gridlayout(3, 2));     pane1.setborder(borderfactory.createlineborder(color.pink, 2, true));  //...  public void buildpane2() {     pane2.setlayout(new gridlayout(2, 2));     pane2.setborder(borderfactory.createlineborder(color.black, 2, true)); 

gives me...
