Answer 3

yes, static methods are the only methods which are directly called with the class name without using the class instance and static methods are the loaded only once. when the <classname>.java file is compiled without errors it will give a <classname>.class file. In turn the <classname>.class file converts into <classname>.main which is a static method. As i already mentioned static methods are directly called with class name.
