The 'javap' tool when invoked with the '-verbose' option gives you the major and minor version of a class file.

Thanks for that.My next question is then:what does the major version number refer to.eg: 49 = 1.5.0_07?48 = ?47 = ?46 = ?etc...Is there a list of what JDK all the major version numbers refer to?
