我在 java 中有两个用户对象，其中包含数据 id、姓名、姓氏、中间名、国家、地区、地区等，我想将他们的数据写入两个单独列中的 pdf(iText7 pdf) 文件。任何建议！
我的代码是：
用户等级：
private int id ;
private String name ;
private String middleName;
private String surname ;
private String email;
private String country;
private String zone;
private String district;
private String city;
private String tole;
private int zip_code;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getMiddleName() {
return middleName;
}
public void setMiddleName(String middleName) {
this.middleName = middleName;
}
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
public String getZone() {
return zone;
}
public void setZone(String zone) {
this.zone = zone;
}
public String getDistrict() {
return district;
}
public void setDistrict(String district) {
this.district = district;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getTole() {
return tole;
}
public void setTole(String tole) {
this.tole = tole;
}
public int getZip_code() {
return zip_code;
}
public void setZip_code(int zip_code) {
this.zip_code = zip_code;
}
