Use this tool http://www.javadecompilers.com/

But recently, a new wave of decompilers has forayed onto the market: Procyon, CFR, JD, Fernflower, Krakatau, Candle.

Here's a list of decompilers presented on this site:

CFR - Free, no source-code available, http://www.benf.org/other/cfr/ Author: Lee Benfield

Very well-updated decompiler! CFR is able to decompile modern Java features - Java 9 modules, Java 8 lambdas, Java 7 String switches etc. It'll even make a decent go of turning class files from other JVM langauges back into java!

JD - free for non-commercial use only, http://jd.benow.ca/ Author: Emmanuel Dupuy

Updated in 2015. Has its own visual interface and plugins to Eclipse and IntelliJ . Written in C++, so very fast. Supports Java 5.

Fernflower - open-source, https://github.com/fesh0r/fernflower Author: Egor Ushakov

Updated in 2015. Very promising analytical Java decompiler, now becomes an integral part of IntelliJ 14. (https://github.com/JetBrains/intellij-community/tree/master/plugins/java-decompiler) Supports Java up to version 6 (Annotations, generics, enums)

JAD - given here only for historical reason. Free, no source-code available, jad download mirror Author: Pavel Kouznetsov
