根据三角形的代码示例，自行编写代码实现如下描述的功能的代码： （1）编写一个 StudentBean 类，在其中定义的学生属性有学号、姓名、性别、籍 贯、年龄、专业，各属性的命名按照 Java 命名

当然，我可以帮你编写一个简单的 `StudentBean` 类。这个类会包含你提到的各种学生属性，并提供相应的getter和setter方法。以下是代码示例：

public class StudentBean {
    // 定义学生属性
    private String studentId;
    private String name;
    private String gender;
    private String hometown;
    private int age;
    private String major;

    // 构造函数
    public StudentBean(String studentId, String name, String gender, String hometown, int age, String major) {
        this.studentId = studentId;
        this.name = name;
        this.gender = gender;
        this.hometown = hometown;
        this.age = age;
        this.major = major;
    }

    // 获取方法
    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 String getGender() {
        return gender;
    }

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

    public String getHometown() {
        return hometown;
    }

    public void setHometown(String hometown) {
        this.hometown = hometown;
    }

    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;
    }
    
    // 重写toString方法，以便于打印学生信息
    @Override
    public String toString() {
        return "StudentBean{" +
                "studentId='" + studentId + '\'' +
                ", name='" + name + '\'' +
                ", gender='" + gender + '\'' +
                ", hometown='" + hometown + '\'' +
                ", age=" + age +
                ", major='" + major + '\'' +
                '}';
    }
}
