Java基础，封装问题person类

1.现有数据记录如下图。请编写：Person类，将图中的数据，封装到Person类对象中，并定义一个ArrayList对象列表，然后完成对列表中的数据：（1）将Person对象添加到列表中；（2）将所有数据的遍历输出（3）删除姓名为tom的对象，并输出删除后的结果。

不知道需要操作数据库么，如果不需要的话，这样实现：
package cs;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

/**

Person
@author lenovo
@version 1.0

/
public class Person {

private Integer id;

private String name;

private Integer age;

private String sex;

private Integer cardId;

/**

@return the id
/
public Integer getId() {
return id;
}

/**

@param id the id to set
/
public void setId(Integer id) {
this.id = id;
}

/**

@return the name
/
public String getName() {
return name;
}

/**

@param name the name to set
/
public void setName(String name) {
this.name = name;
}

/**

@return the age
/
public Integer getAge() {
return age;
}

/**

@param age the age to set
/
public void setAge(Integer age) {
this.age = age;
}

/**

@return the sex
/
public String getSex() {
return sex;
}

/**

@param sex the sex to set
/
public void setSex(String sex) {
this.sex = sex;
}

/**

@return the cardId
/
public Integer getCardId() {
return cardId;
}

/**

@param cardId the cardId to set
/
public void setCardId(Integer cardId) {
this.cardId = cardId;
}

/** (non-Javadoc)

@see java.lang.Object#toString()
/
@Override
public String toString() {
return "Person [id=" + id + ", name=" + name + ", age=" + age + ", sex="
```
      + sex + ", cardId=" + cardId + "]";
```
}

public static void main(String[] args) {

  List<Person> personList = new ArrayList<Person>();
  //(1)将Person对象添加到列表中
  Person p1 = new Person();
  p1.setId(2);
  p1.setName("Rose");
  p1.setSex("女");
  p1.setAge(29);
  p1.setCardId(1);
  Person p2 = new Person();
  p2.setId(3);
  p2.setName("tom");
  p2.setSex("男");
  p2.setAge(27);
  p2.setCardId(2);
  personList.add(p1);
  personList.add(p2);
  //（2）将所有数据的遍历输出
  for (Person person : personList) {
      System.out.println(person.toString());
  }
  //（3）删除姓名为tom的对象，并输出删除后的结果。
  //删除
  Iterator<Person> pIterator = personList.iterator();
  while (pIterator.hasNext()) {
      Person person = pIterator.next();
      if ("tom".equals(person.name)) {
          pIterator.remove();
      }
  }
  System.out.println("输出删除操作后的对象");
  for (Person person : personList) {
      System.out.println(person.toString());
  }

}

Person 类

package test_2;

public class Person {
    private int id;
    private String name;
    private int age;
    private String sex;
    private int card_id;

    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 int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public int getCard_id() {
        return card_id;
    }

    public void setCard_id(int card_id) {
        this.card_id = card_id;
    }

    @Override
    public String toString() {
        return "Person{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age=" + age +
                ", sex='" + sex + '\'' +
                ", card_id=" + card_id +
                '}';
    }
}

主方法

package test_2;

import java.util.ArrayList;
import java.util.List;

public class Main {
    List<Person> list = new ArrayList<Person>();

    public void addStudent() {
        //添加数据
        Person person = new Person();
        person.setId(2);
        person.setName("Rose");
        person.setAge(29);
        person.setSex("女");
        person.setCard_id(1);
        //添加到集合
        list.add(person);

        //添加数据
        Person person1 = new Person();
        person1.setId(3);
        person1.setName("tom");
        person1.setAge(27);
        person1.setSex("男");
        person1.setCard_id(2);
        //添加到集合
        list.add(person1);
    }

    //遍历数据
    public void print() {
        System.out.println(list);
    }

    //删除tom对象
    public void delete() {
        String name = "tom";
        list.removeIf(person -> person.getName().equals(name));
    }

    public static void main(String[] args) {
        Main main = new Main();
        main.addStudent();
        main.print();

        //调用删除方法
        main.delete();
        //打印
        main.print();
    }
}

打印结果：

[Person{id=2, name='Rose', age=29, sex='女', card_id=1}, Person{id=3, name='tom', age=27, sex='男', card_id=2}]
[Person{id=2, name='Rose', age=29, sex='女', card_id=1}]
