用java设计一个学生类，学生信息有身份证号、学号、专业、姓名、性别、年龄及数学、英语、java程序设计三门课程的成绩。创建学生类的对象并输出对象的信息

下面是一个示例代码，仅供参考：

public class Student {
    private String idCardNumber;
    private String studentNumber;
    private String major;
    private String name;
    private String gender;
    private int age;
    private double mathScore;
    private double englishScore;
    private double javaScore;
    
    public Student(String idCardNumber, String studentNumber, String major, String name, String gender, int age,
                   double mathScore, double englishScore, double javaScore) {
        this.idCardNumber = idCardNumber;
        this.studentNumber = studentNumber;
        this.major = major;
        this.name = name;
        this.gender = gender;
        this.age = age;
        this.mathScore = mathScore;
        this.englishScore = englishScore;
        this.javaScore = javaScore;
    }
    
    public String getIdCardNumber() {
        return idCardNumber;
    }

    public void setIdCardNumber(String idCardNumber) {
        this.idCardNumber = idCardNumber;
    }

    public String getStudentNumber() {
        return studentNumber;
    }

    public void setStudentNumber(String studentNumber) {
        this.studentNumber = studentNumber;
    }

    public String getMajor() {
        return major;
    }

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

    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 double getMathScore() {
        return mathScore;
    }

    public void setMathScore(double mathScore) {
        this.mathScore = mathScore;
    }

    public double getEnglishScore() {
        return englishScore;
    }

    public void setEnglishScore(double englishScore) {
        this.englishScore = englishScore;
    }

    public double getJavaScore() {
        return javaScore;
    }

    public void setJavaScore(double javaScore) {
        this.javaScore = javaScore;
    }
    
    public void printInfo() {
        System.out.println("身份证号：" + this.idCardNumber);
        System.out.println("学号：" + this.studentNumber);
        System.out.println("专业：" + this.major);
        System.out.println("姓名：" + this.name);
        System.out.println("性别：" + this.gender);
        System.out.println("年龄：" + this.age);
        System.out.println("数学成绩：" + this.mathScore);
        System.out.println("英语成绩：" + this.englishScore);
        System.out.println("Java程序设计成绩：" + this.javaScore);
    }
}

然后我们可以创建一个 `Student` 对象，并输出其信息：

public class Main {
    public static void main(String[] args) {
        Student student = new Student("123456789012345678", "20210101", "计算机科学与技术", "张三", "男", 20,
                                      90.5, 88.0, 95.0);
        student.printInfo();
    }
}

输出结果如下：

身份证号：123456789012345678
学号：20210101
专业：计算机科学与技术
姓名：张三
性别：男
年龄：20
数学成绩：90.5
英语成绩：88.0
Java程序设计成绩：95.0
