Java程序学生成绩管理.docx

1、Java程序学生成绩管理 学生成绩管理功能：输入10个学生的学号，姓名，4科成绩（数学，英语，Java，计算机基础）。计算出平均成绩，以平均成绩降序输出成绩表。输出全组的各科平均分，最高分和最低分。输入姓名查询。代码:public class SG1 public static void main(String args) new TableTest(); class FrameTest extends JFrame public FrameTest() super(小试牛刀1); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setVisib
