设计一个课程和教材管理系统-小作业

//课程类

public class course {int id;String name;int studyHour;String teacherName;String bookName;//无参构造方法public course() {}//有参构造方法public course(int i, String n, int s, String t, String b) {this.id = i;this.name = n;this.studyHour = s;this.teacherName = t;this.bookName = b;}//更改器public void setCourse(int i, String n, int s, String t, String b) {id = i;name = n;studyHour = s;teacherName = t;bookName = b;}//获取器public String toString(){return "课程编号：" +id + '\t' + "课程名称：" +  name + '\t' + "所需课时：" + studyHour +"课时" + '\t' + "任课教师：" + teacherName + '\t' + "课程书籍：" + bookName;}}

//书籍类

public class Tbook {    int bookId;String bookName;String author;double price;public Tbook(){}public Tbook(int bookId,String bookName,String author,double price){this.bookId = bookId;this.bookName = bookName;this.author = author;this.price = price;}public void setTook(int bookId,String bookName,String author,double price){this.bookId = bookId;this.bookName = bookName;this.author = author;this.price = price;}public String toString(){return "书籍编号: " + bookId + '\t' +"书籍名称：" + bookName +'\t' + "书籍作者:" + author +'\t'+"书籍价格："  + price;}}

//测试类

public class Test {public static void main(String[] args) {course p = new course();p.setCourse(001,"世界与中国", 5, "肖晓明", "中国游记");Tbook t = new Tbook();t.setTook(001, "中国游记", "肖晓明", 35.8);System.out.println(p.toString());System.out.println(t.toString());}}
