关于继承输出父类成员变量name的问题 - 黑马程序员技术交流社区

public class Demo_SuperManTest {
public static void main(String[] args) {
Person p = new SuperMan();
System.out.println(p.name + "......" +p.getName());
}
<p style="line-height: 30px; text-indent: 2em;"></p>
}
/**
人类
*/
public class Person {
String name = "johny"; //++++++++++++++++++++++
// private String name = "johny"; // ****************************************************
public Person() {
super();
}
public Person(String name) {
super();
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
/**
超人类
*/
public class SuperMan extends Person {
String name = "superMan";
public SuperMan() {
super();
}
public SuperMan(String name) {
super();
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
代码现在输出结果是 johny ..... superMan
如果把这句代码 String name = "johny"; //++++++++++++++++++++++
换成这加个private修饰 , private String name = "johny"; //*********************************
用 p对象还怎么调用输出父类的 name 属性 johny ??
