How to get source code from .class file( class file version is 1.2)

Question

Unresolved compilation problem:

Syntax error, parameterized types are only available if source level is 1.5 or greater

I used JD GUI de-compiler but it is giving above error.

is there any way i can get source code

Answer 1

试试javadecompilers.com ，我已经在那里成功地反编译了一些类文件。

Answer 2

Try this at the command line. It will also show the JDK version used to compile the class, in the beginning , like: major version: 52

javap -verbose <class name>
