i need to convert this java code to java applet code

here in my java code:

when i convert my java code to java applet code, there is no error, but when i run the code, the command prompt display

Exeption in thread "main" java.lang.NoSuchMethodError: main

can you please help me to solve my problem.
here is the code that i already converted as applet

Try this.

Member Avatar for sincerelibran

when i convert my java code to java applet code, there is no error, but when i run the code, the command prompt display

Exeption in thread "main" java.lang.NoSuchMethodError: main

This exception occurs because the classpath is not set to the current directory of yours. Yuo can set the classpath from the command prompt.
The command is (from the command prompt type)
classpath=%classpath%;.;drive_name:\current_folder_name and press enter. Once it is done you won't get this error

Well, you don't run applets "from the command line". At least not using "java", use "appletviewer".

Edit: P.S. What does this even have to do with the OP.
