Answer 1

You basically need to set the -target attribute. Also see javac /?.

javac -target 1.5 [...]

Also see this example in javac's documentation.

Update: as per the comments you're using Eclipse, you can just change the compiler compliance level on a per-project basis. Rightclick project > Properties > Java Compiler > Compiler compliance level > 1.5. See screenshot.

You can download JDK 1.5 from the Sun Archive.
