JavaBean

JavaBean两种模型（属性私有化，必须含有无参构造器和setter，getter方法属性只能通过setter，getter访问）：

1、贫血模型（只有私有属性和setter，getter方法）：

1 public class Person {
2
3     private String name;
4     private String addr;
5     private int age;
6
7     public String getName() {
8         return name;
9     }
10
11     public void setName(String name) {
12         this.name = name;
13     }
14
15     public String getAddr() {
16         return addr;
17     }
18
19     public void setAddr(String addr) {
20         this.addr = addr;
21     }
22
23     public int getAge() {
24         return age;
25     }
26
27     public void setAge(int age) {
28         this.age = age;
29     }

2、充血模型（除私有属性和setter，getter方法外，还含有本身的其他方法）：

1 public class Person {
2
3     private String name;
4     private String addr;
5     private int age;
6
7     public String getName() {
8         return name;
9     }
10
11     public void setName(String name) {
12         this.name = name;
13     }
14
15     public String getAddr() {
16         return addr;
17     }
18
19     public void setAddr(String addr) {
20         this.addr = addr;
21     }
22
23     public int getAge() {
24         return age;
25     }
26
27     public void setAge(int age) {
28         this.age = age;
29     }
30
31     public void sing() {
32         System.out.println(name+"is singing");
33     }
