static means that the method/variable/class(inner classes only) can be accessed without creating an instance of the class containing the static method/variable/class. Because of this, static methods may not access non-static methods/variables/classes. Static methods usually provide some function for handling an object (changing a string, reading something from a string (in wrapper classes) etc.) Static variables are usually used as arguments to methods. Static classes are mainly used when a static method needs an inner class. If the inner class was not static, the method would be unable to use it.
