No problem in the class. When you run the program you need to use just the class name drop the .java file extension. javac invokes the compiler and transforms the source file (.java) into a bytecode file (.class) then you run the program by supplying the compiled bytecode file (.class) to the java command that invokes the JVM.

[~s.o.s~]

You don't specify the .java extension when executing Java programs since you are no longer concerned with .java files [the javac command compiles your Java files to the bytecode which is placed in .class files). Read the documentation of the `java' command for more details.

Edit: D'oh, beaten.

whats the format inside ur employee.txt??

[verruckt24]

whats the format inside ur employee.txt??

Whats that gotta do with the "ClassDefNotFound" error in java?

[mrk_chiz]

i can run the program but it stucks with the "Enter Employee Code:"

[verruckt24]

No actually running itself was his problem, since he was using the .java extension to the filename while running.

[shela_1]

how to start the payroll system? can you give me a basic codes?

[stultuske]

shela: this thread is 4 years old. no point in reviving it.
also: the code to run is in the original post. so what 'basic code' are you looking for?

if you don't understand that code, or don't agree with how it was written, do what anyone else would do: write your own.
