    1、Person.java  该JavaBean 用户封装信息



    import java.util.Date;

    public class Person {

            private String name = aaa;

            private String password;

            private int age;

            private Date birthday;

            private Address address;    

            public void setBirthday（Date birthday）{

                this.birthday = birthday;

        }    

            public Date getBirthday（）{

                return birthday;

        }    

            public void setAge（int age）{

                this.age = age;

        }    

            public int getAge（）{

                return age;

        }    

            public void setName（String name）{

                this.name= name;

            

        }

            public String getName（）{

                return name;

        }

            public void setPassword（String password）{

                this.password= password;

            

        }

            public String getPassword（）{

                return password;

        }

            public Address getAddress（） {

                return address;

        }

            public void setAddress（Address address） {

                this.address = address;

        }

    }
