Re-building the class files in JDK 1.6

[Rajesh Balu]

Hi,


I have some class files which are built in JDK 1.5 version.

Now how can i re-build the existing classes in JDK 1.6 if i upgrade the JDK version?



Thanks,

You do it the same way you did before, except you use the javac in your 1.6 installation instead of the one in your 1.5 installation.

If you are thinking about compatibility, you need not worry. Anything compiled in 1.5 would run on 1.5+ (but not the other way round)

[Rajesh Balu]

Yes, it will owrk for sure.

But i want to know, is there any possiblity to build with the upgraded JDK version without using the source code?

[Maneesh Godbole]

No

[Campbell Ritchie]

Yes, it will work, but as you have already been told, it is completely unnecessary.

To be clear, Maneesh's "No" was an answer to this question:

You cannot rebuild your project with a new JDK version if you don't have the source code for the project.

(And as others have said, it's not necessary to rebuild your project with the newer JDK version).

Thanks Everyone....
