How to Build a Path in Eclipse Java
A build path tells the Java Eclipse compiler where to find the source code files for the project. You export your project as a JAR file in Eclipse, then run the code in the DOS prompt with the "classpath" setting. This technique allows you to run the program from a command prompt to test the code. The JAR file is a compiled resource, so your users can use the file to run Java programs on their desktops.
