java program not run

[Amir.php]

i recently installed jdk1.6.0_04 on my winxp system.
Any program i compile, they compile succesfully but when i try to run the following error appeares on cammand prompt(please the attachement) .
please help.
Also please tell me to set path and class path in java.

First reinstall the jdk again.

And save all your programs in other folder, not where jdk is installed.

You can use set path command , but u will need to type it each time u open the cmd prompt. Else u can set path in enviroment variable only once(No need set it again).

Command is :

set path = "X:\Folder_name\bin"
eg. set path = "C:\jdk1.6\bin"

where, X is drive where u hv installed jdk & folder_name is folder name in which jdk is installed.
U can verify whether path is set or not by using command , path.

For enviromental varible :

My computer -- RClick -- Properties -- Advanced --Environment variables -- System variables -- Path -- Edit -- In variable value field -- after the last word if there is a no semicolon type ; else not.
After the semicolon type the path.
eg. ;C:\jdk1.6\bin

Then press ok.

Reopen the cmd prompt and try javac , java command without any file name
it will show u all the options related with commands.

Now compile & run ur programs.

Happy Programming :)
