The Javadoc command line syntax is,
Javadoc [options] [packagenames] [sourcefiles] [@files]
The javap tool is used to get the information of any class or interface. It is also known as a disassembler. The javaw command is identical to java that displays a window with error information, and the javah command is used to generate native method functions.
