Just because you can decompile code doesn't always mean you should . Decompiling software generally breaches the End User License Agreement (EULA) of most commercial software. However, in many jurisdictions, reverse engineering is permitted for interoperability or security research under "fair use" doctrines. Always ensure you are on the right side of the law and ethics before decompiling software you do not own.
Developers often protect proprietary software using (such as ProGuard, Zelix KlassMaster, or Allatori). Obfuscation transforms bytecode into a format that remains fully functional for the JVM but becomes incredibly complex, unreadable, and frustrating for human analysis. Common Obfuscation Tactics decompile java class
Decompilation exists in a complex legal gray area. In many jurisdictions (including the European Union under the Software Directive and the U.S. under fair use case law), decompilation is permitted for —e.g., to allow a separate program to communicate with the decompiled software. However, using decompilation to: Just because you can decompile code doesn't always

Decompilation rarely yields a 100% identical copy of the original source code due to optimizations and information stripped by the compiler:
