Using the CLASSPATH Environment Variable\n\nIf you use a particular set of classes from one or more jar files regularly, it is convenient to set your CLASSPATH environment variable once, log off, then any time afterwards, you just need to invoke javac or java without specifying the -classpath option (as illustrated in later sections).\n\n    * For Windows XP:\n\n         1. Right-click on the My Computer icon\n\n         2. Select Properties\n\n         3. Click on the Advanced tab\n\n         4. Click on the Environment Variables button\n\n         5. Create a new or edit the old CLASSPATH variable for your login account\n\n         6. Add this as a value:\n\n            .;PATH\n\n            where "." represents the current directory, and "PATH" represents the full path to the jar files you want.\n\n         7. Click on OK buttons until you have closed the Properties.\n\n         8. Log off, then log back on to ensure that your environment variables are set.

You need to make sure that there is a file called cap.java, and that the class in this file has a main() method.\n\nNext, compile the code with\njavac cap.java\n\nThis should produce cap.class\n\njava cap\n\nshould then work. \n\nOh, but I'm assuming that "." is in your classpath. If not, then java won't see stuff in the current directory. As a quick fix, try:\n\njava -classpath "."  cap\n\nand see if it starts working.

make sure that the method ReturnBook is not a void but instead returns a boolean value.\n\nIf you want to follow the standard java naming conventions rename the method to "returnBook". Methods typically start with a small letter.\n\nkeep a bookmark to this page that contains all possible\njava compiler error messages for future reference:\n\nhttp://mindprod.com/jgloss/compileerrormessages.html
