Even with the best tools, the output is rarely identical to the original source code. You should expect:
Obfuscators rename classes/vars to a , b , c . Try: decompile jar file
Some tools like Bytecode Viewer let you view code from CFR , FernFlower , and Procyon in parallel. Since different decompilers handle modern Java features (like Lambdas or switch expressions) differently, this ensures you get the most accurate reconstruction.
JD-GUI is perhaps the most famous standalone tool. It’s a lightweight, graphical utility that lets you drag and drop a JAR file and browse the source code instantly. Quick, one-off inspections. # Download cfr

CFR is an excellent command-line decompiler that is frequently updated to support the newest Java language features. It is particularly good at decompiling complex code structures that might confuse other tools. Quick, one-off inspections
While traditional tools like JD-GUI or CFR provide a "static" look at the code, advanced tools like or Recaf allow you to compare multiple decompilers side-by-side or even edit and re-save the JAR. Key Features to Explore
