用java写出1、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Python、c++、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。

在Java中，你可以按照下面的方式来设计一个学生类（Student），包含所需的属性和构造方法，以及用于输出信息的方法：

public class Student {
    private String idNumber;
    private String studentId;
    private String major;
    private String name;
    private String gender;
    private int age;
    private double pythonScore;
    private double cppScore;
    private double javaScore;

    // 构造函数
    public Student(String idNumber, String studentId, String major, String name, String gender, int age,
                   double pythonScore, double cppScore, double javaScore) {
        this.idNumber = idNumber;
        this.studentId = studentId;
        this.major = major;
        this.name = name;
        this.gender = gender;
        this.age = age;
        this.pythonScore = pythonScore;
        this.cppScore = cppScore;
        this.javaScore = javaScore;
    }

    // 获取和设置方法
    public String getIdNumber() { return idNumber; }
    public void setIdNumber(String idNumber) { this.idNumber = idNumber; }

    // ... (类似其他属性的getter和setter)

    // 输出学生信息的方法
    @Override
    public String toString() {
        return "学生信息:\n" +
                "身份证号: " + idNumber + "\n" +
                "学号: " + studentId + "\n" +
                "专业: " + major + "\n" +
                "姓名: " + name + "\n" +
                "性别: " + gender + "\n" +
                "年龄: " + age + "\n" +
                "Python成绩: " + pythonScore + "\n" +
                "C++成绩: " + cppScore + "\n" +
                "Java成绩: " + javaScore + "\n";
    }
}

// 创建学生对象并输出信息
public static void main(String[] args) {
    Student student = new Student("1234567890", "001", "计算机科学", "张三", "男", 20, 85.0, 90.0, 92.0);
    System.out.println(student);
}

在这个例子中，我们首先定义了一个`Student`类，然后在`main`方法中创建了一个`Student`对象，并通过`toString()`方法打印出学生的详细信息。
