JDiff - What Really Changed? @ JDJ
release notes are usually high-level descriptions of feature changes. product reference manuals tend to be large. and its hard to compare different product versions in web browsers windows. suns j2se 1.4 product, with all its new features, is no exception. when you want to know exactly what changed between two versions of a file, "diff" is the familiar command-line tool for the job. when you want a precise comparison between two java apis, i suggest using jdiff.

figures 1 and 2 show typical html documentation generated by jdiff. in this case, the j2se 1.3.0 api and the j2se 1.4.0 api are compared using jdiff 1.0.6. figure 1 is a screenshot of some of the packages that were changed between versions, and figure 2 shows the details for a particular class, java.lang.throwable. every change in the api is reported, from new methods and fields to changes in parameter types and which exceptions are thrown. even the changes in the documentation for each class and method can be reported.

the best way to view a jdiff report is with a web browser. (the report comparing j2se 1.3 and j2se 1.4 can be found at www.jdiff.org.)

one of the most common questions java developers ask after downloading a new version of a product is: "what really changed?" jdiff is an open source java tool, based on javadoc and developed by the author, that produces html documentation describing the precise api changes between two versions of a product.

this article uses jdiff to show what changed between j2se 1.3 and j2se 1.4, and describes how developers can use jdiff to document the changes between two versions of their own products as easily as running javadoc.
