Static Import - This facility lets you avoid qualifying static members with class names without the shortcomings of the "Constant Interface antipattern.
用法
import static java.util.Arrays.*;
导入的是Arrays这个类中的所有静态成员
当类名重名时,需要指定具体的包名
当方法重名时,需要指定具体的对象或类
例子
1: //import static java.lang.Math.max;//静态导入max静态方法
2: import static java.lang.Math.*;//静态导入Math类中的所有静态方法

10: public static void main(String[] args) {

12: double a = max(3, 6);
13: //当静态方法重名时,方法前面要加上类名以示区分
14: double b = StaticImport.pow(3, 2);
15: double c = Math.pow(3, 2);
