NAME
     javap - Java class file disassembler

SYNOPSIS
     javap [ -b ] [ -c ] [ -classpathpath ] [ -h ] [ -J flag ]
          [ -l ] [ -package ] [ -private ] [ -protected ]
          [ -public ] [ -s ] [ -verbose ] [ -verify ]
          [ -version ] class . . .

DESCRIPTION
     The javap  command  disassembles  a  Java  class  file.  The
     options determine the output.  If no options are used, javap
     displays the public fields and methods of the classes passed
     to  it.   The  javap  command displays its output to stdout.
     For example, compile the following class declaration:

          import java.awt.*;
          import java.applet.*;

          public class DocFooter extends Applet {
                    String date;
                    String email;

                    public void init() {
                         resize(500,100);

                         date = getParameter("LAST_UPDATED");
                         email = getParameter("EMAIL");
                    }

                    public void paint(Graphics g) {
                         g.drawString(date + " by ",100, 15);
                         g.drawString(email,290,15);
                    }
          }


     The output from javap DocFooter yields:

          Compiled from DocFooter.java
          public class DocFooter extends java.applet.Applet {
               java.lang.String date;
               java.lang.String email;
               public void init();
               public void paint(java.awt.Graphics);
               public DocFooter();
          }


OPTIONS
     The following options are supported.

     -b             Ensures backward compatibility with javap  in
                    JDK 1.1.

     -c             Prints out disassembled code,  that  is,  the
                    instructions    that    comprise   the   Java
                    bytecodes, for each of  the  methods  in  the
                    class.

     -classpathpath 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 colons. Thus the
                    general format for path is:

                         .:<your_path>

                    For example:

                         .:/home/avh/classes:/usr/local/java/classes


     -h             Generates code that can  be  placed  to  a  C
                    header file.

     -J flag        Passes flag directly to runtime system.

     -l             Displays line and local variable tables.

     -package       Default; shows only package,  protected,  and
                    public classes and members.

     -private       Shows all classes and members.

     -protected     Shows only protected and public  classes  and
                    members.

     -public        Shows only public classes and members.

     -s             Displays internal type signatures.

     -verbose       Prints stack size, number of locals, and args
                    for methods.

     -verify        Runs the verifier.

     -version       Prints out the javap version string.

ENVIRONMENT VARIABLES
     CLASSPATH      Used to provide the system  with  a  path  to
                    user-defined    classes.    Directories   are
                    separated by colons.  For example:

                         .:/home/avh/classes:/usr/local/java/classes
