Java Interface Format

Let me first talk about how to make the program look cool in JBuilder!
The default Java program appearance (lookandfeel) can be changed to the Java appearance, Motif appearance, Windows appearance, and Mac appearance;
Java looks in five different styles: Sapphire, emerald, Ruby, charcoal,
High contrast style.
The method for changing the appearance is as follows:

1: You can directly call one of the following three in the program: Import javax. Swing .*;
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 ");

2: Import javax. Swing .*;
Jmenubar MB = new jmenubar ();
Jmenu file = new jmenu ("Look & feel", true );
Buttongroup = new buttongroup ();
Final uimanager. lookandfeelinfo [] info = uimanager. getinstalledlookandfeels ();
For (INT I = 0; I <info. length; I ++ ){
Jradiobuttonmenuitem item = new
Jradiobuttonmenuitem (info [I]. getname (), I = 0 );
Final string classname = info [I]. getclassname ();
Item. addactionlistener (New actionlistener (){
Public void actionreceivmed (actionevent AE ){
Try {uimanager. setlookandfeel (classname );}
Catch (exception e) {system. Out. println (E );}
Swingutilities. updatecomponenttreeui (touchyfeely. This );}
});
Buttongroup. Add (item );
File. Add (item );
}
MB. Add (File );
Setjmenubar (MB );
}
