贪食蛇的实现源码

package array;
//编写一个Student类，类元素有学生姓名、年龄、成绩(name\age\grade)，写一个
//方法，实现可以打印出10个学生。方法名称createStudentByArray(Student[] s)
/*编写四个方法，分别为根据学生的姓名查询此学生的成绩、根据学生成绩查询学生姓名、
 * 查询所有学生的姓名、查询最差成绩的学生
老师类；
编写调用学生方法的业务方法，要求可以在老师类中操作学生的方法，实现可以根据
学生的姓名查询此学生的成绩（）通过get方法（）??、根据学生成绩查询学生姓名、
查询所有学生的姓名、查询最差成绩的学生。
