直接上代码:
class Father { private String aaa = "我来测试"; public Father() { System.out.println("father this.getClass():"+this.getClass());//表示当前运行时的对象的class System.out.println("father this.hashCode(:"+this.hashCode()); System.out.println("father this:"+this); System.out.println("father this.aaa:"+this.aaa); this.test(); } private void test(){ System.out.println("我是私有化的方法"); } public int dowork() { System.out.println("我要去工作了"); return 1; } } class Son extends Father { private String bbb = "我来测试1"; public Son() { System.out.println("son super.getClass():"+super.getClass());//表示父类运行时的class System.out.println("son this.hashCode():"+this.hashCode()); System.out.println("son this:"+this); } } public class FatherDemo{ public static void main(String[] args) { Father f = new Son(); } }
运行结果是这样的:
father this.getClass():class xiaomage.Son
father this.hashCode(:581882789
father this:xiaomage.Son@22aed3a5
father this.aaa:我来测试
我是私有化的方法
son super.getClass():class xiaomage.Son
son this.hashCode():581882789
son this:xiaomage.Son@22aed3a5
