12. Java Programming: From Problem Analysis to Program Design, 5e To simplify the use of (public) static methods of a class, Java 5.0 introduces the following import statements: These are called static import statements. After including such statements in your program, when you use a (public) static method (or any other public static member) of a class, you can omit the name of the class and the dot operator.
