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. 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.
The keyword static allows main() to be called without having to instantiate a particular instance of the class. This is necessary since main() is called by the Java interpreter before any objects are made. The keyword void simply tells the compiler that main() does not return a value.gain static method of a particular class can be accessed only by referring to the class like: Class_name.method_name(); So a class need not to be instantiated before accessing a static method. So the main() method is declared as static so that it can be accessed without creating an object of that class.
