What's the difference between Java and Java2?

i was just wondering what the difference was between them. I see a lot of books that say Java and Java2, but I don't know which one to buy.

Is it that Java is an older language and Java2 is the books I should get? Or should I get the older Java books first.

Hi this is suman

Java 2 means the second edition of Java in theory. In practice Java also refers to Java 2.

thanks

There are number of difference beetween Java and java 2

1. Java 2 allows policy to define what code can and cannot do. JDK 1.1 trusts code completely or does not trust it at all.
2. Java 2 does allow Certificate Authorities to sign generated certificates. JDK 1.1 does not support certificates from Certificate Authorities.
3. Java 2 has keytool for certificate management and jarsigner for signing and verifying JARs. JDK 1.1 has one tool, javakey, for all code-signing related functions
