com.sun.java.swing.plaf.windows.WindowsLookAndFeel

Answer 1

try{
        UIManager.setLookAndFeel("com.sun.java.swing.plaf.motif.MotifLookAndFeel");
//UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");
//UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
