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.

Static Data members: In a class the data members (variables) are of two types, * static variables. * instance variables (non static) In case of instance variable one separate copy of value will be available for each object. For static variables there will be only one copy of value for all the objects.
