A good answer might be:

Of course.


Java Documentation

(If you don't know about DOS windows, skip this section.) A simple test is to open a command line window (a DOS window) and CD to C:\j2sdk1.4.2\bin. Type "javac" after the prompt.

C:\j2sdk1.4.2\bin>javac

The java compiler should run, briefly. It will write out about 15 lines of instructions on how to use it. (Details on how to use it come later in this chapter.)

While you are at java.sun.com (or later if you don't have time) get the Java documentation. This comes in a file j2sdk-1_4_2-doc.zip. You will have to "un-zip" it after you download it. On most computers un-zipping a file can be started by clicking on the file name. You will end up with a set of web pages (stored on your computer) that describe the features of Java.

QUESTION 3:

When you create a program, do you keep it in the same directory as the compiler?
