After mine starting with Java, did I have by the Realisation of "HelloWorld.java" treyed to realise "HelloWorldSWT". But this Windows Version of HelloWorld [
public class HelloWorldSWT {

public static void main(String[] args) {
// TODO Auto-generated method stub
Display display = new Display();
Shell shell = new Shell(display);
shell.setText("Hello world!");
shell.open();
while(!shell.isDisposed()) {
if(!display.readAndDispatch())
display.sleep();
}
display.dispose();
}

}
] didn't be compiled or interpreted in mine sense.
I get in the line "Display display = new Display();" the message/errore "Display can not resolved to a type", and in the "Shell shell = new Shell(display);"-line the errore "Shell shell = new Shell(display);" in the similar way!
What do I've to do? What is wrong?
I think and thought that the problem the missing definition of the variables "Display" and "Shell" is, but is that realy the fact, by the reason that I found these code on a book and a popluar web-page?
