Java 2 in 21 Days: A Fistful of Java

ROGERS CADENHEAD

Day 1: A Fistful of Java

If you're a Windows user having trouble with "Bad command or filename" errors or "Class not found" errors during this chapter, read the online tutorial Using the Java Development Kit on a Windows System.

Q: I saw your book, decided enough is enough, and bought it so I could learn Java. I thought Sun's Java Development Kits were always free, so how come the license for 1.2 is only for 90 days? Don't you think you should have mentioned that rather predominately in your book? -- B.F.
A: Sun has always been strongly commited to giving the JDK away for free, and I haven't read anything to indicate a change in that policy. My guess is that the 90-day license was offered because you're working with a beta release of the JDK, and the final release won't have that reference to a time limit.
