编写一个封装学生信息的JavaBean，类名为StudentFrom，类中包含学号、姓名、性别、年龄、联系电话、E-mail、住址等属性

下面是一个简单的JavaBean示例，封装了学生的基本信息：

public class StudentForm {
    private String id; // 学号
    private String name; // 姓名
    private String gender; // 性别
    private int age; // 年龄
    private String phone; // 联系电话
    private String email; // E-mail
    private String address; // 住址

    // 构造方法
    public StudentForm(String id, String name, String gender, int age, String phone, String email, String address) {
        this.id = id;
        this.name = name;
        this.gender = gender;
        this.age = age;
        this.phone = phone;
        this.email = email;
        this.address = address;
    }

    // getter/setter方法
    public String getId() {
        return id;
    }

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

    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 int getAge() {
        return age;
    }

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

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

以上代码中，我们定义了一个包含学生信息的JavaBean类StudentForm，它有学号、姓名、性别、年龄、联系电话、E-mail、住址等属性，同时提供了构造方法和getter/setter方法，以方便对学生信息进行封装和访问。
