1、利用构造方法实现方法重载，编写一个学生类:student,类的组成如下: 成员变量:学号，姓名，年龄，专业

以下是实现方法重载的学生类代码：

public class Student {
    private String studentID;
    private String name;
    private int age;
    private String major;

    public Student(String studentID, String name, int age, String major) {
        this.studentID = studentID;
        this.name = name;
        this.age = age;
        this.major = major;
    }

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

    public String getStudentID() {
        return studentID;
    }

    public void setStudentID(String studentID) {
        this.studentID = studentID;
    }

    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 getMajor() {
        return major;
    }

    public void setMajor(String major) {
        this.major = major;
    }
}

请问还有什么问题需要我回答吗？
