We keep all "executable files"(like .exe files) and "batch
files"(like .bat) in path variable. And we keep all jar
files and class files in classpath variables.

So path is set according to the .exe files & .bat files And
classpath is set according to the .jar files & .class files.


Operating system tries to find .exe and .bat files in path
and JVM tries to find all classes in classpath.

set path is loading the environment variables with operating
system or javac.

setting the path in windows xp.
steps to set path for java:
1. go to ->my computer-> properties->advanced->
->environment variables.
2. in this window go to system variables and select -> new
3. now in variable write: classpath
4. write code as soon here in variable value:
;.;C:\Program Files\Java\jdk1.5.0\bin;
5. click ok and ok and ok
