使用静态内部类提高封装性
Java中的嵌套类分为两种：静态内部类和内部类。静态内部类就是在内部类的申明中加上static的修饰符。
实例：
““
package com.company;
public class Person {
private String name;
private Home home;
public Person(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Home getHome() {
return home;
}
public void setHome(Home home) {
this.home = home;
}
/**
* 静态内部类的调用
*/
public static class Home {
private String address;
private String tel;
public Home(String address, String tel) {
this.address = address;
this.tel = tel;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
}
}
““
主函数：
““
package com.company;
import java.util.Random;
public class Main {
public static void main(String[] args) {
Person p = new Person(“张飞”);
p.setHome(new Person.Home(“三国”,”11234551”));
System.out.println(p.getName());
System.out.println(p.getHome().getAddress());
System.out.println(p.getHome().getTel());
}
}
