为什么java项目都要写实体类

1. java实体类怎么写

java实体类怎么写

1.java的实体类应该怎么写,给个例子

public class BillLattice {

private String lcode； //开票网点编码

private String lname； //开票网点名称

private String tid； //纳税人识别号

private String brand； //税控设备品牌

private String model； //税控设备型号

private String fcode； //税控设备编码

public BillLattice(String lcode, String lname, String tid, String brand, String model, String fcode) {

super();

this.lcode = lcode;

this.lname = lname;

this.tid = tid;

this.brand = brand;

this.model = model;

this.fcode = fcode;

}

public BillLattice() {

super();

}

public String getLcode() {

return lcode;

}

public void setLcode(String lcode) {

this.lcode = lcode;

}

public String getLname() {

return lname;

}

public void setLname(String lname) {

this.lname = lname;

}

public String getTid() {

return tid;

}

public void setTid(String tid) {

this.tid = tid;

}

public String getBrand() {

return brand;

}

public void setBrand(String brand) {

this.brand = brand;

}

public String getModel() {

return model;

}

public void setModel(String model) {

this.model = model;

}

public String getFcode() {

return fcode;

}

public void setFcode(String fcode) {

this.fcode = fcode;

}

2.帮我用java写个实体类啊

import java.util.Date;

public class PersonalMember {

private int id;

private String name;

private String password;

private int gender;

private String email;

private String telephone;

private String fax;

private String postalCode ;

private Date lastLoginTime;

private Date registerDate;

public PersonalMember()

{

}

public int getid()

{return id;}

public String getname()

{return name;}

public String getpassword()

{return password;}

public int getgender()

{return gender;}

public String getemail()

{return email;}

public String gettelephone()

{return telephone;}

public String getfax()

{return fax;}

public String getpostalCode()

{return postalCode;}

public Date getlastLoginTime()

{return registerDate;}

public Date getregisterDate()

{return registerDate;}

public void setid(int id)

{this.id=id;}

public void setname(String name)

{this.name =name;}

public void setpassword(String password)

{this.password=password;}

public void setgender(int gender)

{this.gender =gender;}

public void setemail(String email)

{this.email=email;}

public void settelephone(String telephone)

{this.telephone=telephone;}

public void setfax(String fax)

{this.fax=fax;}

public void setpostalCode(String postalCode)

{this.postalCode=postalCode;}

public void setlastLoginTime(Date registerDate)

{this.registerDate=registerDate;}

public void setregisterDate(Date registerDate)

{this.registerDate=registerDate;}

}

3.谁能帮我写下java实体类

@Entity@Table(name = "t_book")public class Book implements Serializable{ private static final long serialVersionUID = -2738902322135434977L; @GenericGenerator(name = "generator", strategy = "uuid") @Id @GeneratedValue(generator = "generator") @Column(name = "uuid", unique = true, nullable = false, length = 32) private String uuid; @Column(name = "t_type) private int type; @Column(name = "t_Name", length =30) private String name; @Column(name = "t_Author", length = 30) private String naAuthor；自己生成get set 方法。
