Hi.

Im a Java newb, im majoring cs in college... and i just started so i was wondering if there is a place i can find a complete list of java commands... and how do i turn a .class file into a permanently executable file.... can anyone help so that i can just double click the prog i make and it executes.. i remember being able to do this with c++.

www.javasoft.com Java is a bit different than c++. Unless if you have a java compiler that compiles to the native platform your pretty much out of luck with the .exe However you can make a jar file that is excutable.

http://java.sun.com/j2se/1.4.2/docs/api/ Has the commands I think you think you want. Or do you mean the jar, javac, javaw java type thingees in the JDK?

For the jar file you use the jar command

<pre>
Usage: jar {ctxu}[vfm0M] [jar-file] [manifest-file] [-C dir] files ...
Options:
-c create new archive
-t list table of contents for archive
-x extract named (or all) files from archive
-u update existing archive
-v generate verbose output on standard output
-f specify archive file name
-m include manifest information from specified manifest file
-0 store only; use no ZIP compression
-M do not create a manifest file for the entries
-i generate index information for the specified jar files
-C change to the specified directory and include the following file
If any file is a directory then it is processed recursively.
The manifest file name and the archive file name needs to be specified
in the same order the 'm' and 'f' flags are specified.

Example 1: to archive two class files into an archive called classes.jar:
jar cvf classes.jar Foo.class Bar.class
Example 2: use an existing manifest file 'mymanifest' and archive all the
files in the foo/ directory into 'classes.jar':
jar cvfm classes.jar mymanifest -C foo/ .
</pre>

and edit the manifest changing the main class entry to match your class

C:\directory>jar cvf thing.jar Cruncher.class
added manifest
adding: Cruncher.class(in = 3673) (out= 2050)(deflated 44%)

This isn't actually executable in the proper sense, but hey.
