java写一个学生类包含属性有学号性别姓名年龄 实现操作增加一个学生 根据学号删除某个学生 所有学生年龄增加一岁 按数组显示所有学生信息

public class Student {
private String id;
private String gender;
private String name;
private int age;

public Student(String id, String gender, String name, int age) {
this.id = id;
this.gender = gender;
this.name = name;
this.age = age;
}

public String getId() {
return id;
}

public void setId(String id) {
this.id = id;
}

public String getGender() {
return gender;
}

public void setGender(String gender) {
this.gender = gender;
}

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;
}

// 增加一个学生
public static void addStudent(List<Student> students, Student student) {
students.add(student);
}

// 根据学号删除某个学生
public static void deleteStudent(List<Student> students, String id) {
Iterator<Student> iterator = students.iterator();
while(iterator.hasNext()) {
Student student = iterator.next();
if(student.getId().equals(id)) {
iterator.remove();
}
}
}

// 所有学生年龄增加一岁
public static void increaseAge(List<Student> students) {
for(Student student : students) {
student.setAge(student.getAge() + 1);
}
}

// 按数组显示所有学生信息
public static void displayStudents(List<Student> students) {
for(Student student : students) {
System.out.println("学号：" + student.getId() + "，性别：" + student.getGender() + "，姓名：" + student.getName() + "，年龄：" + student.getAge());
}
}
}
