Can we need to create special class for main method

No as long as is inside of a class somewere in your program that all that matters.

Answer 2

In Java,the main method has to be inside a class.

Every Java program must have at least one class and only one main method with String array parameter. Main method must be inside of a class, but you don't need to have special class for it.

Answer 4

no, we already mention that... public static void main(string args[]){}in java, in starting of every java program.
