Java 如何在程序中包含排序方法？

以下是该计划的要求。基本上，输出必须如下所示，同时仍遵循以下指导原则。我的问题是如何修改我的程序以满足要求#4（即编写一种方法，以1-D和2-D数组获取学生数据并打印学生记录：姓名、2个测验分数和平均值。输出字段应对齐。）我的第二个问题是如何满足要求#6（学生记录前应打印一行标题，每2名学生打印一行“------------------------”

---

名称1

姓名2

---

姓名3

姓名4

---

姓名5

================================================================================== 1.在main（）方法中，定义一个可存储5个学生姓名的一维数组。在main（）中定义一个可存储5个学生（行）考试记录的二维数组，每个学生有3个数据字段（列）：2个测验分数和2个测验的平均值

将学生姓名（实名）分配给1-D数组，并将2个测验分数分配给2-D数组

计算每个学生2次测验的平均值

4.编写一个方法，获取学生数据（1-D和2-D数组），并按平均字段从高到低排序学生记录。

编写一个方法，获取学生数据（1-D和2-D数组）并打印学生记录：姓名、2个测验分数和平均值。输出字段应对齐

6.学生记录前应打印一行标题，每两名学生应打印一行“------------------------”。

以下输出是一个示例：

名称Q1 Q2平均值

---

名称1

姓名2

---

姓名3

姓名4

---

姓名5

=================================================================================

这是我到目前为止所拥有的。我在排序方法和每两个学生打印一行“-----------------”方面确实有问题。
