Linux and Java command

[Sudhanshu Mishra]

Hi all,
I am facing a problem whose reason i am unable to understand.
I am running linux on my syatem,and java version 7.0.
When i try to compile a code it does fine,but running a code by java command always gives the error that 'Main method not found.please declare it as pulic static void main(String[] args',even if i have a perfectly written main method like this: public static void main(String...a).
I have already checked the classpath and every thing seems fine.
What could be the possible reason?
Please help me out.
Thanks....

Please post the actual code, and how are you compiling and running it from terminal.

Post your code then only may be we can figure it out.

There's a critical difference between String and String[]. If you don't declare the main method's one and only argument as String[], it won't look like a main method. Java finds methods using their signatures, which are strings of specially-coded text that contain the method name, the return type, and the types of all their parameter arguments, so if you use the wrong parameter type, the wrojng signature will be generated and Java won't find the method.
