hi,

if u r using notepad the default will be saved with *.ext

if so do like this "firstEx.java" and save as u r common folder

and make sure that u added the classpath to the in evniroment variables so that java and javac will be excecuted

let me know u need any further info

It also exists in C: folder

hi,

if so check the classpath

for example

http://java.sun.com/j2se/1.3/docs/tooldocs/win32/classpath.html

http://java.sun.com/docs/books/tutorial/essential/environment/paths.html

in the above link u have to write applications in bin folder

when u r writing in u r personal folder

http://mindprod.com/jgloss/classpath.html

let me know u need any further info

Hi bvr,

i write a small java program and execute in commandprompt , iam getting the output.

i think my classpath is not a problem.

when iam executing that file "first.Ex.java"

it is showing error it cannot read.

Thanks

hi sridevigunda,

if classpath is not a problem

try like this

javac c:\fristEx.java ( javac and complete location of the java file )
