写一个Java程序,实现以下要求: 学生参加某课程的考试,课程类型分为考试课和考查课 考试课最终成绩计算方法:出勤*10%+作业*10%+实验*10%+期末*70% 考查课最终成绩计算方法:出勤*20%+作业*10%+实验*10%+期末*60%

你可以创建一个名为`Course`的抽象类作为课程的基础类型，然后为`ExamCourse`和`CreditCourse`分别作为具体的子类来实现不同的成绩计算方式。以下是一个简单的示例：

// 定义抽象类 Course
abstract class Course {
    protected String name;
    protected int attendance;
    protected int homework;
    protected int experiment;
    protected int finalExam;

    public Course(String name, int attendance, int homework, int experiment, int finalExam) {
        this.name = name;
        this.attendance = attendance;
        this.homework = homework;
        this.experiment = experiment;
        this.finalExam = finalExam;
    }

    // 普通方法计算总成绩，子类需要覆盖这个方法
    public abstract double calculateTotalScore();

    // 公共方法供外部获取信息
    public String getName() {
        return name;
    }
}

// 实现 ExamCourse 类型
class ExamCourse extends Course {
    @Override
    public double calculateTotalScore() {
        return (attendance * 0.1) + (homework * 0.1) + (experiment * 0.1) + (finalExam * 0.7);
    }
}

// 实现 CreditCourse 类型
class CreditCourse extends Course {
    @Override
    public double calculateTotalScore() {
        return (attendance * 0.2) + (homework * 0.1) + (experiment * 0.1) + (finalExam * 0.6);
    }
}

public class Main {
    public static void main(String[] args) {
        ExamCourse examCourse = new ExamCourse("Java", 90, 85, 92, 88);
        System.out.println("Exam Course Name: " + examCourse.getName());
        System.out.println("Total Score: " + examCourse.calculateTotalScore());

        CreditCourse creditCourse = new CreditCourse("Maths", 95, 80, 87, 82);
        System.out.println("\nCredit Course Name: " + creditCourse.getName());
        System.out.println("Total Score: " + creditCourse.calculateTotalScore());
    }
}
