上节课讲了父类和子类，这节课直接拿代码举例子
父类代码：
package com.xuenixiang.web;
public class JiChengFuLei {
private String name;
private String address;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
子类代码：
package com.xuenixiang.web;
public class JiChengZiLei extends JiChengFuLei {
private int age;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public void xuenixiang() {
System.out.println("网站名："+this.getName());
System.out.println("网站地址："+this.getAddress());
System.out.println("网站年龄："+this.getAge());
}
}
