How can i use jar file?

Question

I have a jar file that contains some classes that I want to use in my project. I work on the command line, not in eclipse.

Please tell me how should I use these classes in the jar file for my project.

Use the -classpath command-line option:

javac -classpath library.jar MyProgram.java

And then, to run it, specify the class path again - including where your actual code is:

java -classpath library.jar;. MyProgram

(Suppose you are using Windows. On Unix, use: instead, as a path separator.)

A jar file is a way to package java classes. To use the classes in the jar file, you need to include the jar in your classpath.

You simply include it in your classpath as follows:

java -cp otherclasspath;thejar.jar yourlass
