I am a trainer and my project is to upgrade a transcompiler from Java 1.3 to 1.5, I am a beginner in Java and I want to khnow if there is a tool that will help me, I took the first step by reading the new features of 1.4 and 1.5 then we decided that I have to add this features : Generics - Metadata - Autoboxing - Enumerations - Var args - Enhanced for each loop. So if you can tell me what is the next step and if there is a tool that upgrade the code to a recent version ? thank you

Java is usually pretty good at being backwards compatible. It will probably "just work"Richard Tingle– Richard Tingle2014-01-10 13:31:20 +00:00Commented Jan 10, 2014 at 13:31

Just try to compile and then test the code, fix anything that doesn't work.
You don't have to use the new features just because they are there.
Why upgrade to 5 though? You should go to 7 really if going through the pain of doing an upgrade as the extra pain will be very small and you will be up to date for longer.

I did ask why not to upgrade to 1.7 and they said they will see if there is a feature that will need in 1.6 or 1.7, you suggest to compile the code but that's not what I need because the transcompiler work well but they want to change the source code ( I don't know why) to a recent version

1.7 is more recent, is properly maintained, has security fixes, better performance, etc. It's not a matter of needing a specific feature.
