I had made a tutorial about path and classpath. I would recommend to go through it. You can fint it here

In short, PATH is used by the operating system to find executable files (.exe's in Windows) that it can run. CLASSPATH, on the other hand is specifically used by Java to find .class files that are needed when you run a Java program.

Setting the PATH variable allows you "to conveniently run the JDK executables (javac.exe, java.exe, javadoc.exe, etc.) from any directory without having to type the full path of the command." To set the PATH, see these installation instructions for 32-bit Windows. (For other operating systems, click here.)

Setting the CLASSPATH variable "tells JDK tools and applications where to find third-party and user-defined classes." To set the CLASSPATH, see these JavaRanch instructions or Sun instructions.
