Why main class is always public in java?

Answer 3

In order to run any Java code, you have to "kcik it off" and if the Public Main() function were Private or Protected, there would be no way for a system process (web page, command-line batch file, executible) to start your code. Once it's off an running, you can make everything else Protected or Private.
