* [sc](sc.md) - check the info for the classes loaded by JVM
* [sm](sm.md) - check methods info for the loaded classes
* [dump](dump.md) - dump the loaded classes in byte code to the specified location
* [redefine](redefine.md) - load external `*.class` files and re-define it into JVM
* [jad](jad.md) - decompile the specified loaded classes
* [mc](mc.md) - Memory compiler, compiles `.java` files into `.class` files in memory
* [redefine](redefine.md) - load external `*.class` files and re-define it into JVM
* [dump](dump.md) - dump the loaded classes in byte code to the specified location
* [classloader](classloader.md) - check the inheritance structure, urls, class loading info for the specified class; using classloader to get the url of the resource e.g. `java/lang/String.class`
By default, the decompile result will have the `ClassLoader` information. With the `--source-only` option, you can print only the source code. Conveniently used with the [mc](mc.md)/[redefine](redefine.md) commands.
