A Decompiler is a software tool that translates machine code or bytecode back into a higher-level programming language. This process is often used to analyze or recover source code from compiled programs, making it easier for developers to understand how a program works. Decompilers are particularly useful in situations where the original source code is lost or unavailable. Decompilers can handle various programming languages, including Java, C, and C++. They work by reversing the compilation process, which typically involves converting human-readable code into a format that a computer can execute. While decompilation can help in debugging and learning, it may raise legal and ethical concerns regarding software copyright and intellectual property.
