Does .class file contains information about compiler version?

I have class file. It is a result of compilation. Can I know the compiler version which was used for creation of this file?

As a result I want to know something like java 1.6.0_45

Yes, that information is part of class file. More information here.

Edit: I stand corrected. The compiler version is not part of the class file. I confused major and minor versions with compiler version. Still keeping the link since it provides useful information pertaining to the question.

No. Class file contains only format version which is not directly corresponds to compiler version.

PS: Class files mainly can be found inside jars. Jars often contains manifests. Manifest may contain compiler version.
