Hi,
I have a simple problem. I have downloaded a open source java project. And i tried to "build" it using Ant tool. The build has failed. And all the errors are related to "enum" keyword saying that "cannot use the 'enum' keyword as a variable.
I want to know whether "enum" keyword has become the part of java only with java 1.5?

Regards
vijay

So all the legacy code which has used "enum" as a variable name will not work with Java1.5 with changing the code.

The fix is to change the variable but meanwhile you can compile as follows:

<javac souce="1.4" target="1.4" ...

or

<javac souce="1.4" target="1.5" ...

for 5.0 compliant input/output

<javac source="1.5" target="1.5" ...


In other words, indicate the version of java the source was written in and what your target platform is. Keep in mind that Java 5.0 runs 1.2, 1.3, 1.4 binaries. As you might imagine, 1.5 is a better compiler than 1.4 so using Java 5.0 for all your needs is a very good idea. You can use any input form and generate any output form.
