How do you stop the error Java is not recognized as an internal or external command operable program or batch file?

If you are getting that error, it means that either Java is not installed, or is not in your path.
If Java is not installed, go to http://www.java.com to install the most recent version of the JRE.
If you're sure you have already installed Java ensure the Java executable is in your system's path. You can do this by first finding the directory it is installed in. For example, mine is installed in C:\Program Files\Java\jre6. The executables are located in the bin directory.
In order to set your path (Assuming Windows Vista), go to Start -> Control Panel -> System, then click on the 'Advanced System Settings' link on the left, then the 'Environment Variables' button. In the lower section (Labeled 'System Variables'), scroll through and find the item labeled 'Path' and double click it. In the field labeled 'Variable value' go to the end and add a semicolon (;), and then the path your installation of Java is located. Using the example I gave above, I would have added ;C:\Program Files\Java\jre6\bin to the end of the line.
The procedure for 64-bit Windows Vista or Windows 7 is the same, except the text you will add to the Path variable is ";C:\Program Files (x86)\Java\jre6\bin". Notice there is still a semi-colon at the beginning of the line.
Once you have done this, you will need to close and reopen the command prompt if it is already open, and you should be able to run java without getting this error message.

How can you undo something you put into command prompt?
There is usually no way to undo a command. Everything executed in the command prompt, is usually final, and has to be manually undone via the same way it was done. There are some command line programs that allow you to undo what it has done. But with the vagueness of your question I am unable to give you a definitive answer. NOTE: Deleting a file from the command line is irreversible and external software will be needed to retrieve the file.

Why UNIX commands are divided into internal and external commands?
An internal command is one that is built in to the shell interpreter and is likely to be used quite a bit. An external command is a file in a directory that can be searched, loaded, and executed. The reason for having internal commands is for performance; it takes a lot less time to have the shell just execute the given internal command than it would take to find it on the system, load it into memory, and then execute it.
