Answer 1

//录入课程 public void addCourses(Course[] courses) { System.out.println("请输入学生信息：格式为课程号,课程名,学分"); String str; String sInfor[]; for (int i = 0; i < courses.length; i++) { str = scan.next(); sInfor = str.split(","); courses[i] = new Course(sInfor[0], sInfor[1], Double.parseDouble(sInfor[2])); } } //显示所有课程 public void displayCourses(Course[] courses) { for (int i = 0; i < courses.length; i++) { System.out.println("课程号：" + courses[i].getCourseId() + ",课程名：" + courses[i].getCourseName() + ",学分：" + courses[i].getCredit()); } } //删除某门课程 public void delCourses(Course[] courses) { System.out.println("请输入要删除课程的编号："); String courseId = scan.next(); for (int i = 0; i < courses.length; i++) { if (courses[i].getCourseId().equals(courseId)) { courses[i] = null; System.out.println("删除成功！"); } } } //录入教师 public void addTeachers(Teacher[] teachers) { System.out.println("请输入教师信息：格式为工号,姓名,性别,电话,职称,年龄"); String str; String sInfor[]; for (int i = 0; i < teachers.length; i++) { str = scan.next(); sInfor = str.split(","); teachers[i] = new Teacher(sInfor[0], sInfor[1], sInfor[2], sInfor[3], sInfor[4], Integer.parseInt(sInfor[5])); } } // 显示教师所有信息 public void displayTeachers(Teacher[] teachers) { for (int i = 0; i < teachers.length; i++) { System.out.println("工号：" + teachers[i].getTeaId() + ",姓名：" + teachers[i].getTeaName() + ",性别：" + teachers[i].getSex() + ",电话：" + teachers[i].getTel() + ",职称：" + teachers[i].getProfessor() + ",年龄：" + teachers[i].getAge());

    }
}

//教师排课 public void assignTeachCourses(Teacher[] teachers, Course[] courses) { System.out.println(); System.out.println("\t课程信息系如下："); for (int i = 0; i < courses.length; i++) { System.out.println("课程号：" + courses[i].getCourseId() + "\t" + "课程名称：" + courses[i].getCourseName()); } System.out.println(); System.out.println("请选择课程，格式为：课程号1,课程号2,......"); for (int i = 0; i < teachers.length; i++) { System.out.println("工号：" + teachers[i].getTeaId() + "，姓名：" + teachers[i].getTeaName() + " 排课(请输入课程号)："); String[] cIds = scan.next().split(","); teachers[i].setTeachCourse(cIds);

    }
}

//查询教师与课程号的对应信息 public void showCourses(Teacher[] teachers, Course[] courses) {

    System.out.println("教师与课程号的对应关系如下：");
    for (int i = 0; i < teachers.length; i++) {
        if (teachers[i].teachCourse.length > 0) {
            for (int j = 0; j < teachers[i].teachCourse.length; j++) {
                System.out.println("课程号：" + teachers[i].teachCourse[j]
                        + "\t" + "课程名称：" + courses[Integer.parseInt(teachers[i].teachCourse[j]) - 1].getCourseName() + "\t教师工号：" + teachers[i].getTeaId() + "\t教师姓名：" + teachers[i].getTeaName());

            }
        }
    }
