Java学习：十一.this和static---实例代码块
本文共 595 字，大约阅读时间需要 1 分钟。
一.语法格式
{ Java代码块1； Java代码块2； … } 二.特点 只要调用构造函数，必然在构造函数调用之前调用实例代码块。public class InstanceTest { public static void main(String[] args) { System.out.println("main begin"); new InstanceTest(); new InstanceTest("w"); new InstanceTest(); new InstanceTest("x"); System.out.println("main over"); } { System.out.println("实例代码块"); } public InstanceTest() { System.out.println("无参构造函数"); } public InstanceTest(String name) { System.out.println("有参构造函数"+name); }} 结果：
从结果中可以看出，实例代码块在构造函数之前调用，而且调用的次数可以不止一次。 三.作用 为程序员准备的时机，叫做对象构造时机。 转载地址：http://uxlk.baihongyu.com/
