The trailer I decided to use as the base for this off-road trailer project is Harbor Freight's Haul-Master 1,720-pound-capacity Super Duty 48x96-inch utility trailer with 12-inch, five-lug wheels and pneumatic tires (part #94564). It's made from 2x4-inch steel C-channel, uses a 2-inch hitch ball, and is DOT-approved.
They are public because they must be accessible to the JVM to begin execution of the program. Main is the first method that would get executed in any class. They are static because they must be available for execution without an object instance.you may know that you need an object instance to invoke any method. So you cannot begin execution of a class without its object if the main method was not static.hey are public because they must be accessible to the JVM to begin execution of the program.

A static function is one that can be called on the class itself, as opposed to an instance of the class. For example a non-static would be: This method works on an instance of the class, not the class itself. However you can have a static method that can work without having an instance.
