怎么用java做一個簡單的學(xué)生管理系統(tǒng)?

用java寫的話,可以用List來實現(xiàn)學(xué)生管理系統(tǒng):\x0d\x0a首先,管理系統(tǒng)是針對學(xué)生對象的,所以我們先把學(xué)生對象就寫出來:\x0d\x0apackage bean;\x0d\x0apublic class Student {\x0d\x0a String name;\x0d\x0a String studentId;\x0d\x0a String sex;\x0d\x0a int grade;\x0d\x0a public Student(String name,String studentId,String sex,int grade){\x0d\x0a this.name= name;\x0d\x0a this.studentId= studentId;\x0d\x0a this.sex = sex;\x0d\x0a this.grade = grade; \x0d\x0a }\x0d\x0a public int getGrade(){\x0d\x0a return grade;\x0d\x0a }\x0d\x0a public String getName(){\x0d\x0a return name;\x0d\x0a }\x0d\x0a public String getSex(){\x0d\x0a return sex;\x0d\x0a }\x0d\x0a public void setGrade(int g){\x0d\x0a this.grade = g;\x0d\x0a }\x0d\x0a public String getStudentId(){\x0d\x0a return studentId;\x0d\x0a }\x0d\x0a}\x0d\x0a這里面定義了一些得到當(dāng)前學(xué)生對象數(shù)據(jù)的一些get方法,和成績修改的set方法,代碼很簡單,就不做詳細(xì)的解答。\x0d\x0a就下來就是我們的正文了。\x0d\x0a雖然我們暫時不用swing來做界面,但是總得要看的過去吧,所以,先做了一個比較簡單的界面:\x0d\x0a System.out.println("***************");\x0d\x0a System.out.println("*歡迎來到學(xué)生管理系統(tǒng) *");\x0d\x0a System.out.println("*1:增加學(xué)生 *");\x0d\x0a System.out.println("*2:刪除學(xué)生 *");\x0d\x0a System.out.println("*3:修改成績 *");\x0d\x0a System.out.println("*4:查詢成績 *");\x0d\x0a System.out.println("***************");\x0d\x0a System.out.println("您想選擇的操作是:");\x0d\x0a這里可以看到,我們的是用一個1234來選擇項目,說以不得不講一下Java如何獲取到鍵盤所輸入的數(shù)據(jù)---------Scanner ,要使用這個,首先需要import進來一個包:\x0d\x0a例如這里:\x0d\x0aimport java.util.*;\x0d\x0a之后的兩行代碼搞定輸入:\x0d\x0aScanner sc = new Scanner(System.in);\x0d\x0a int choice = sc.nextInt();\x0d\x0a接下來就是各個功能的實現(xiàn):\x0d\x0a\x0d\x0apackage test;\x0d\x0aimport java.util.*;\x0d\x0aimport bean.Student;\x0d\x0apublic class Manager {\x0d\x0a static List StudentList = new LinkedList();\x0d\x0a public static void main(String[] agrs){\x0d\x0a select(StudentList); \x0d\x0a }\x0d\x0a private static void select(List StudentList ){\x0d\x0a System.out.println("***************");\x0d\x0a System.out.println("*歡迎來到學(xué)生管理系統(tǒng) *");\x0d\x0a System.out.println("*1:增加學(xué)生 *");\x0d\x0a System.out.println("*2:刪除學(xué)生 *");\x0d\x0a System.out.println("*3:修改成績 *");\x0d\x0a System.out.println("*4:查詢成績 *");\x0d\x0a System.out.println("***************");\x0d\x0a System.out.println("您想選擇的操作是:");\x0d\x0a Scanner sc = new Scanner(System.in);\x0d\x0a int choice = sc.nextInt(); \x0d\x0a switch(choice){\x0d\x0a //增加學(xué)生\x0d\x0a case 1:\x0d\x0a System.out.print("請輸入學(xué)生的姓名:");\x0d\x0a Scanner Sname = new Scanner(System.in);\x0d\x0a String name = Sname.nextLine();\x0d\x0a System.out.print("請輸入學(xué)生的性別:");\x0d\x0a Scanner Ssex = new Scanner(System.in);\x0d\x0a String sex = Ssex.nextLine();\x0d\x0a System.out.print("請輸入學(xué)生的學(xué)號:");\x0d\x0a Scanner SId = new Scanner(System.in);\x0d\x0a String studentId = SId.nextLine();\x0d\x0a System.out.print("請輸入學(xué)生的成績:");\x0d\x0a Scanner Sgrade = new Scanner(System.in);\x0d\x0a int grade = Sgrade.nextInt();\x0d\x0a StudentList.add(new Student(name,studentId,sex,grade));\x0d\x0a System.out.println("添加成功!?。。?!");\x0d\x0a select(StudentList);\x0d\x0a break;\x0d\x0a //刪除學(xué)生成績\x0d\x0a case 2:\x0d\x0a System.out.print("請告訴我需要刪除學(xué)生的學(xué)號:");\x0d\x0a Scanner Sid = new Scanner(System.in);\x0d\x0a String SstudentId = Sid.nextLine();\x0d\x0a boolean isfindDelete = false;\x0d\x0a for (int i = 0; i

用Java 實現(xiàn)一個簡單的學(xué)生管理系統(tǒng)! 求代碼,求代碼?。。?!

完成了,希望能幫到你

剛開始會叫你輸入編號選擇功能

import java.io.*;

public class student {

public static void main(String args[]) throws IOException{

int[] stud = {77,99,55,46,82,75,65,31,74,85};

System.out.println("請選擇功能:");//輸入編號選擇功能

System.out.println("1、輸入學(xué)號,查詢該學(xué)生成績:");

System.out.println("2、輸入成績,查詢學(xué)生學(xué)號:");

System.out.println("3、輸入學(xué)號,刪除該學(xué)生成績");

System.out.println("請選擇編號:");

BufferedReader td = new BufferedReader(new InputStreamReader(System.in));

String temp = td.readLine();

int choice = Integer.valueOf(temp);

if(choice == 1){//一為查詢學(xué)生成績

System.out.println("請輸入學(xué)號:");

BufferedReader sd = new BufferedReader(new InputStreamReader(System.in));

String temp_sd = sd.readLine();

int No = Integer.valueOf(temp_sd);

System.out.print("學(xué)號為 "+No+" 的學(xué)生成績?yōu)椋?" + stud[No-1] +"分");

}

if(choice == 2){//二為查詢學(xué)生編號

System.out.println("請輸入成績:");

BufferedReader sd = new BufferedReader(new InputStreamReader(System.in));

String chengji = sd.readLine();

int temp_cj = Integer.valueOf(chengji);

for(int i=0;istud.length;i++){

if(temp_cj == stud[i]){

System.out.print("成績?yōu)?"+ temp_cj+ "的學(xué)生的學(xué)號為: "+(i+1));

}

}

}

if(choice == 3){//三為刪除操作

System.out.println("請輸入學(xué)號:");

BufferedReader sd = new BufferedReader(new InputStreamReader(System.in));

String temp_sd = sd.readLine();

int No = Integer.valueOf(temp_sd);

stud[No-1]=0;//直接賦值為0,不刪除學(xué)生

System.out.print("學(xué)號為 "+No+" 的學(xué)生成績?yōu)椋?" + stud[No-1] +"分");

}

}
