javap

-help 
Prints out help message for javap. 
-l 
Prints out line and local variable tables. 
-b 
Ensures backward compatibility with javap in JDK 1.1. 
-p lic 
Shows only p lic classes and members. 
-protected 
Shows only protected and p lic classes and members. 
-package 
Shows only package, protected, and p lic classes and members. This is the default. 
-private 
Shows all classes and members. 
-Jflag 
Pass flag directly to the runtime system. Some examples:

javap -J-version 
javap -J-Djava.security.manager -J-Djava.security.policy=MyPolicy MyClassName

-s 
Prints internal type signatures. 
-c 
Prints out disassembled code, i.e., the instr tions that comprise the Java bytecodes, for each of the methods in the class. These are documented in the Java Virt l Machine Specification. 
-verbose 
Prints stack size, number of locals and args for methods. 
-classpath path 
Specifies the path javap uses to look up classes. Overrides the default or the CLASSPATH environment variable if it is set. Directories are separated by semi-colons. Thus the general format for path is: 
.; 
For example: 
.;C:\usrs\dac\classes;C:\tools\java\classes 
-bootclasspath path 
Specifies path from which to load bootstrap classes. By default, the bootstrap classes are the classes implementing the core Java platform located in jre\lib\rt.jar and several other jar files. 
-extdirs dirs 
Overrides location at which installed extensions are searched for. The default location for extensions is the val 
of java.ext.dirs.
