I believe that many people when learning Java always find the main function is used like this:

public static void main (String args[])

so why is that?
main () “method type” is void, indicating that the method does not return a value. It has a parameter, “GRAS,” which is an array of objects of type String. The method declaration for main() is fixed and cannot be changed. The access modifier for the
main () method is public, so you can run the program (call the method) from anywhere.
