Java Product Version Confusion

I'm reading a book on Java 1.1 that refers to various classes that do not exist in Microsoft Visual J++ Professional Edition, Version 1.1, which apparently installs V1.02 libraries. How can I update the Microsoft Java API packages to Version 1.1, which is what I thought I bought?

I'm addressing this question because a lot of people have run into this problem. There are many Java development products out there, and they all have different version numbers. Sometimes, as a marketing technique, the products will use the same version number as the latest Java release. Sometimes it is pure coincidence that version numbers match up. However, just because a product has the same version number as the latest Java release does not mean that it is compatible with the latest Java release. You should always closely read the information about a Java product before buying it. Java continues to evolve at a rapid pace, and it is difficult for vendors to stay up to date. To answer the question, you should download the latest Microsoft SDK for Java (version 3.0 as of March 1998) from the Microsoft web site to get Java 1.1 classes and virtual machine. You may also want to download the trial version of Visual J++ 6.0 to see if there is a special upgrade discount for owners of previous versions.
