Decompiling and disassembling are both kinds of a reverse engineering process that do the opposite of what a compiler and an assembler do.
A decompiler translates a compiled binary's low-level code designed to be computer readable into human-readable high-level code. The accuracy of decompilers depends on many factors like the amount of metadata present in the code being decompiled and the complexity of the code (not in terms of algorithms, but in terms of sophistication of the high-level code used). The bytecode format used by Java Virtual Machine (JVM) and the intermediate language used by .NET framework Common Language Runtime (CLR) include, in most cases, a very extensive amount of information and high level features. This makes the process of creating a high-level code from a compiled input quite feasible, and in most cases, very reliable. Most of the decompilation processes pass through seven steps before producing a readable high level code: loading...
