Java API to find out the JDK version a class file is compiled for?

Question

Are there any Java APIs to find out the JDK version a class file is compiled for? Of course there is the javap tool to find out the major version as mentioned in here. Howev

Answer 1

This gets you the contents of the class file:

MysteryClass.class.getResourceAsStream("MysteryClass.class")

Then look at bytes 5-8 to get the minor and major version. A mapping between those numbers and the JDK releases can be found here.
