1.要编写类文件 2.javabean是一些可移植，可重用并且可以组装到应用程序中的java实体类
bean/User.java是实体类， dao/MyDb.java是访问数据库的工具
User.java
package bean
;
public class User {
private String username
;
private String password
;
private String realname
;
private String mobile
;
private Integer age
;
public void setUsername(String username
) {
this.username
= username
;
}
public String
getUsername() {
return username
;
}
public void setPassword(String password
) {
this.password
= password
;
}
public String
getPassword() {
return password
;
}
public void setRealname(String realname
) {
this.realname
= realname
;
}
public String
getRealname() {
return realname
;
}
public void setMobile(String mobile
) {
this.mobile
= mobile
;
}
public String
getMobile() {
return mobile
;
}
public void setAge(Integer age
) {
this.age
= age
;
}
public Integer
getAge() {
return age
;
}
public User(String username
, String password
) {
this.username
= username
;
this.password
= password
;
}
public User() {
}
@Override
public String
toString() {
return "User [username=" + username
+ ", password=" + password
+ ", realname=" + realname
+ ", mobile=" + mobile
+ ", age=" + age
+ "]";
}
}
