1.Student.java代码如下

*/

}
}
2.OurClass.java代码如下
import java.util.ArrayList;
import java.util.List;

}
}
/**
* 删除学生
*
* @param stuNo
* 学号
*/
public void delStudent(String stuNo) {

}
/**
* 显示全部学生
*/
public void displayAllStudent() {

}
}
/**
* 显示学生信息

* @param stu
* 学生对象
*/
public void display(Student stu) {
System.out.println("This student's info: " + stu);
}
/**
* 查找学生
*
* @param stuNo
* 学号
* @return null or stu
*/
public Student findStudent(String stuNo) {

}
}
return null;
}
public static void main(String[] args) {

// 添加五个学生
System.out.println("
----------------- Add Student -----------------
");
for (int index = 0; index < 5; index++) {
lab.addStudent(new Student("" + index, "stu" + index));
}
// 显示全部学生
System.out.println("
----------------- Display Student -----------------
");
lab.displayAllStudent();
// 删除第一位学生
System.out.println("
----------------- Delete Student -----------------
");
lab.delStudent("" + 0);
// 显示升序的所有学生
System.out.println("
----------------- Remain Student -----------------
");
lab.displayAllStudent();
// 根据学号查找学生
System.out.println("
----------------- Find Student -----------------
");
lab.display(lab.findStudent("4"));
}
}
