A Java class decompiler is a tool that takes a compiled Java class file (.class) as input and generates a Java source code file (.java) that is semantically equivalent to the original compiled code. The decompiled code may not be identical to the original source code written by the developer, but it should be functionally equivalent. decompiler java class
