try {     for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels())         {         if ("Windows".equals(info.getName()))             {             javax.swing.UIManager.setLookAndFeel(info.getClassName());             break;             }         }     }catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {         Logger.getLogger(WizardForm.class.getName()).log(Level.SEVERE, null, ex);     }

You can change the part shown in bold (Windows) to Nimbus, Metal, Motif, System, GTK etc. YOu can change the Look and Feel (LookAndFeel) of your java application simply by changing the text shown bold into above specified names of Look and Feels.
