Getting started with Java

"A beginner's guide to Java programming"

Running your first Java application

Now the time has come, (said the Walrus). You're ready to run your first Java application. From a dos prompt or Unix session, enter the directory where your source code and class file is stored, and type the following :

java myfirstjavaprog

You should not type java myfirstjavaprog.class.  All Java classes end in this extension, it is not necessary, and will cause an error messages.

Your Java application will load, display its message, and then terminate. Congratulations!

Summary

Writing and developing Java applications and applets need not be a great mystery. Armed with the JDK and a text editor, virtually any programmer can write in Java. You've just taken the first step, in a long journey, towards learning Java.
