you need to have a JDK or SDK download them from http://www.java.sun.com/

for an introduction to java have a look at this
http://www.ibiblio.org/javafaq/course/index.html

and for some short programs and goog tutorials go to
http://java.sun.com/docs/books/tutorial/

if you download a JDK i think the latest is 1.4.0
to compile from command prompt write
javac filename.java

and to run the program
java filename

in java your filename has to be the same as the class name

like if you have
class HelloWorldApp {
    public static void main(String[] args) {
        System.out.println("Hello World!"); //Display the string.
    }
}

your filename has to be HelloWorldApp.java
when you compile it you will see another file with the same name but .class that is the bytecode when you run it you dont put the .class just the file name after "java".

Well the emphasis on the filename, the name of the class
steps on how to run and deburg are well illucidated. But I would like to undersand what does the word class result or basically mean.ie does it mean an entity or is just a name choosen by the programmer?
