本文目录一览:

JAVA:编写一个学生成绩管理系统。学生的属性包括学号、姓名、年龄等。

class Student{

String name;

String id;

int age;

Couse[] course;

}

class Course{

String coursename;

float pscourse;

float qzcourse;

float sxcourse;

float qmcourse;

float zpcourse;

}

这个要写好长时间的,定义几个类;然后实现具体的功能。用数组或者集合来存储学生信息还有成绩信息,最后定义一个测试类。你可以找我私聊,1368270359qq

可以仿照我的做一下,希望采纳,我才一级哦

学生成绩管理系统源代码 SQL+JAVA

这个东西,虽说很简单,但是也会费点时间,还是建议花钱买吧,这样要,不会有几个人会专门去给你写的,除非他之前写过类似的课程设计。

如何用Java语言编写学生成绩管理系统

package student;

int flag = 1;

while(flag == 1){

System.out.println("1.输入学生信息");

System.out.println("2.通过姓名查找学生信息");

System.out.println("3.显示全部学生信息");

System.out.println("4.退出系统");

int op = sc.nextInt();

switch(op){

case 1:stum.addStudent(n);

new Scanner(System.in).nextLine();

break;

case 2:

System.out.println("输入学生姓名:");

case 3:

简单的JAVA学生管理系统代码···

lListStudent students = new ArrayListStudent();

BufferedReader br = new BufferedReader(new FileReader("D:\student.txt"));

String tmpStr = br.readLine();

while(tmpStr != null){

int firstIndex = tmpStr.indexOf(" ");

int secondIndex = tmpStr.indexOf(" ",firstIndex + 1);

int thirdIndex = tmpStr.indexOf(" ", secondIndex + 1);

int forthIndex = tmpStr.indexOf(" ", thirdIndex + 1);

Integer stuId = Integer.parseInt(tmpStr.substring(0,firstIndex));

String stuName = tmpStr.substring(firstIndex + 1,secondIndex);

Integer stuYW = Integer.parseInt(tmpStr.substring(secondIndex + 1,thirdIndex));

Integer stuSX = Integer.parseInt(tmpStr.substring(thirdIndex + 1,forthIndex));

Integer stuYY = Integer.parseInt(tmpStr.substring(forthIndex + 1));

Student student = new Student();

student.setStuId(stuId);

student.setStuName(stuName);

student.setStuYW(stuYW);

student.setStuSX(stuSX);

student.setStuYY(stuYY);

students.add(student);

tmpStr.readLine();

}

//创建一个学生实体类 封装stuId stuName stuYW stuSx stuYY 这5个属性。。。

//已经帮你把数据拆分出来 并以Student 对象的形式放入集合中了 接下来 给分吧 哇咔咔
