java學(xué)生成績管理系統(tǒng)

1、注：這個(gè)程序要結(jié)合下面3個(gè)類才能運(yùn)行：學(xué)生信息可以自己加/*1編寫一個(gè)學(xué)生成績管理程序。學(xué)生的屬性包括學(xué)號、姓名、年齡等。每個(gè)學(xué)生要學(xué)習(xí)若干課程，每門課程有平時(shí)成績、期中考試成績、實(shí)習(xí)成績、期末考試成績以及總評成績等多個(gè)成績，其中平時(shí)成績的數(shù)目不定（因?yàn)椴煌n程的教師布置的平時(shí)作業(yè)數(shù)不同），而總評成績是其它成績的平均值。 請先設(shè)計(jì)合理的對象容器類存放這些信息，然后設(shè)計(jì)程序完成以下功能： 1）列出某個(gè)學(xué)生的所有成績； 2）列出某門課程每個(gè)學(xué)生的總評成績，及所有學(xué)生總評成績的總評分； 3）分區(qū)段統(tǒng)計(jì)某門課程的學(xué)生總評成績，例如60 分以下的學(xué)生人數(shù)、60 至70 分的學(xué)生人數(shù)等。 根據(jù)興趣，你還可

2、實(shí)現(xiàn)其它一些功能。請仔細(xì)設(shè)計(jì)和組織你的類和使用的集合類對象。*/package com.geminno.day730.homework12;import java.util.ArrayList;import java.util.List;public class TestStudentManage public static void main(String args) List<Student> students = new ArrayList<Student>();/實(shí)例化對象List<Course> courses = new ArrayList<
