SWT (jface) experience opening multiple forms

Code It is very simple, as shown below: Copy code The Code is as follows: Package swt_jface.demo1;
Import org. Eclipse. SWT. SWT;
Import org. Eclipse. SWT. Graphics. GC;
Import org. Eclipse. SWT. Graphics. image;
Import org. Eclipse. SWT. Widgets. display;
Import org. Eclipse. SWT. Widgets. shell;
Public class main {

Public static void main (string [] ARGs ){

Display display = New Display ();

Image small = new image (display, 16, 16 );
GC = new GC (small );
GC. setbackground (display. getsystemcolor (SWT. color_red ));
GC. fillarc (0, 0, 16, 16, 45,270 );
GC. Dispose ();

Image Large = new image (display, 32, 32 );
GC = new GC (large );
GC. setbackground (display. getsystemcolor (SWT. color_blue ));
GC. fillarc (0, 0, 32, 32, 45,270 );
GC. Dispose ();

Shell shell = new shell (Display );
Shell. settext ("small and large icons ");
Shell. setimages (new image [] {small, large });
Shell shell2 = new shell (Display );
Shell2.settext ("small icon ");
Shell2.setimage (small );

Shell. open ();
Shell2.open ();
While (! Shell. isdisposed ()){
If (! Display. readanddispatch ())
Display. Sleep ();
}
Display. Dispose ();
}
}
