1.声明一个Person类：
package com.xuzhiwen.test1; public class Person { public int age; public String name; public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getName() { return name; } public void setName(String name) { this.name = name; } }2.声明一个带静态代码块的类：
package com.xuzhiwen.test1; public class StaticTest { public static Person p ; static{ p = new Person(); } public static Person getPerson(){ return p; } }3. 写一个测试类：
package com.xuzhiwen.test1; public class Test { public static void main(String[] args) { Person p1 = StaticTest.getPerson(); Person p2 = StaticTest.getPerson(); System.out.println(p1==p2); } }4.运行结果为：
