static：

不能使用this

public class Person {    Person() {        System.out.println("---Constructor");    }    static {        System.out.println("---static");    }    public void get() {        System.out.println("---get");    }        public static void find() {        System.out.println("---find");    }        public  static void main(String[] args) {        System.out.println("---not load");        Person p = new Person();            p.get();        p.find();        Person.find();    }}

---static---not load---Constructor---get---find---find

static就好像定义作用域工作在”全局“

class People {    static int i = 0;    public People(int b) {        i = b;    }}public class Person {        public  static void main(String[] args) {        People  p1 = new People(1);        People  p2 = new People(2);        People  p3 = new People(3);                System.out.println("p1" + "---" + p1.i);        System.out.println("p2" + "---" + p2.i);        System.out.println("p3" + "---" + p3.i);    }}

p1---3p2---3p3---3
