HelloAWT.java - My First AWT Program
This section provides a tutorial example on how to write a simple Java AWT program. HelloAWT.java is my first AWT program that displays a blank window with 'Hello world!' in the window title bar.
Below is my first AWT program, HelloAWT.java:
import java.awt.Frame; public class HelloAWT { public static void main(String[] a) { Frame f = new Frame("Hello world!"); f.setVisible(true); } }
If you have JDK installed on your system, you can compile and run this program in a command window:
herong> javac HelloAWT.java herong> java HelloAWT
Once the program is running, you will see a small new window showing up on your screen. If use the mouse pointer to drag its edges to make it larger, you can see the hello text in the title area as shown in this picture:
The new window will stay on your screen until you press Ctrl-C in the command window to terminate the running program.
