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

System.out.println("請(qǐng)選擇編號(hào)：");

Java實(shí)現(xiàn)簡(jiǎn)易學(xué)生信息管理系統(tǒng)

使用JFileChooser來選擇打開文件， 使用FileInputStream進(jìn)行讀取文件，F(xiàn)ileOutputStream來寫文件 這些沒什么難度吧。中間的顯示，你就直接用JFileArea就是了，然后設(shè)置為自動(dòng)換行。

怎么用java做一個(gè)簡(jiǎn)單的學(xué)生管理系統(tǒng)？

用java寫的話，可以用List來實(shí)現(xiàn)學(xué)生管理系統(tǒng)：\x0d\x0a首先，管理系統(tǒng)是針對(duì)學(xué)生對(duì)象的，所以我們先把學(xué)生對(duì)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(duì)象數(shù)據(jù)的一些get方法，和成績(jī)修改的set方法，代碼很簡(jiǎn)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(shí)不用swing來做界面，但是總得要看的過去吧，所以，先做了一個(gè)比較簡(jiǎn)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(jī) *");\x0d\x0a System.out.println("*4：查詢成績(jī) *");\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(gè)1234來選擇項(xiàng)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(gè)，首先需要import進(jìn)來一個(gè)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(gè)功能的實(shí)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(jī) *");\x0d\x0a System.out.println("*4：查詢成績(jī) *");\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(qǐng)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(qǐng)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(qǐng)輸入學(xué)生的學(xué)號(hào)：");\x0d\x0a Scanner SId = new Scanner(System.in);\x0d\x0a String studentId = SId.nextLine();\x0d\x0a System.out.print("請(qǐng)輸入學(xué)生的成績(jī)：");\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(jī)\x0d\x0a case 2:\x0d\x0a System.out.print("請(qǐng)告訴我需要?jiǎng)h除學(xué)生的學(xué)號(hào)：");\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
