Java中对static的理解与应用一例

/*面试笔试中经常遇到的关于static关键字的题目，仅供参考，如有补充欢迎下方留言。

下面这段代码的输出结果是什么？

*/

public class Test extends Father{

static String strinTest="strinTest";∥类的变量

static{∥静态代码块

System.out.println("test static");

}

public Test(){

System.out.println("test constructor");

}

public static void main(String[] args) {

System.out.println("test member static-->"+strinFather);

System.out.println("test member static-->"+strinTest);

new Test();

}

}

class Father{

static String strinFather="strinFather";∥类变量

static{∥静态代码块

System.out.println("Father static");

}

public Father(){

System.out.println("Father constructor");

}

}

/*运行结果顺序充分说明了static的执行顺序

Father static

test static

test member static-->strinFather

test member static-->strinTest

Father constructor

test constructor
