Can Java comments be seen by decompiling?

I was wondering if I put comments in my code and when someone tried to decompile it, if they could read the comments that I put?

No. And you can verify this by using DJ Java Decompiler, for example. If you also refer to the Java Class File Format, you'll see there's no construct for storing comments.

Comments aren't included in the .class files, so a decompiler won't be able to produce them.

No, comments are never included as part of the compilation process. They are typically removed in some sort of pre-processing, or first-pass stage.

Nope, comments are discarded by the compiler.
