how is java annotation represented in java bytecode

问题

I tried to decompile a .class file that contains JUnit tests. I read the byte code, but I did not see any clue of the @Test annotation(it's used in the java source code).

As metadata, how are annotations represented in bytecode?

回答1:

Annotations appear just before the byte code of the thing it is associated with. If you are not seeing the annotations it could be an old de-compiler (most of them are)
