java學生信息管理系統代碼

㈠ 用java實現學生信息管理系統

不就是一個c/s架構的，學生信息管理系統嘛，晚上給你發過去。

㈡ 21題 java 簡單學生信息管理系統 控制台程序

怎麼給你？已經做好了！！

Student.java代碼如下：

publicclassStudent{
//學號
privateStringxh;
//姓名
privateStringname;
//性別
privateStringsex;
//成績
privatedoublecj;
//讀取學號的方法
publicStringgetXh(){
returnxh;
}
//設置學號的方法
publicvoidsetXh(Stringxh){
this.xh=xh;
}
//獲取姓名的方法
publicStringgetName(){
returnname;
}
//設置名字的方法
publicvoidsetName(Stringname){
this.name=name;
}
//獲取性別的方法
publicStringgetSex(){
returnsex;
}
//設置性別的方法
publicvoidsetSex(Stringsex){
this.sex=sex;
}
獲取成績的方法
publicdoublegetCj(){
returncj;
}
//設置成績的方法
publicvoidsetCj(doublecj){
this.cj=cj;
}

publicvoidshowMe(){
System.out.println("姓名為"+name+"
性別為"+sex+"
學號為"+xh
+"
成績為"+cj);
}

㈢ Java實現一個簡單的學生信息管理系統

看了你的需求,其實除了java,你還可以用易查分來做查詢管理系統呢!通過易查分 不用寫代碼,上 傳個excel表格就可以生成,超級簡單的!

㈣ Java實現學生簡易信息管理系統

importjava.util.*;
importjava.io.*;

classStuMgr{

	publicstaticclassStudent{
	
		publicintid;
		publicStringname;
		publicintage;
		
		publicStudent(intid,Stringname,intage){
			this.id=id;
			this.name=name;
			this.age=age;
		}
		
		@Override
		publicStringtoString(){
			returnid+","+name+","+age;
		}
	}
	
	publicList<Student>stuList=newLinkedList<>();
	
	publicvoidadd(){
		Scannersc=newScanner(System.in);
		System.out.println("請輸入學生學號：");
		Stringid=sc.nextLine();
		intintId=0;
		try{
			intId=Integer.parseInt(id);
		}catch(NumberFormatExceptionex){
			System.out.println("學號輸入有誤，請輸入數字！");
			return;
		}
		if(find(intId)!=null){
			System.out.println("該學號已經存在！");
			return;
		}
		System.out.println("請輸入學生姓名：");
		Stringname=sc.nextLine();
		System.out.println("請輸入學生年齡：");
		Stringage=sc.nextLine();
		intintAge=0;
		try{
			intAge=Integer.parseInt(age);
		}catch(NumberFormatExceptionex){
			System.out.println("年齡輸入有誤，請輸入數字！");
			return;
		}
		Studentstu=newStudent(intId,name,intAge);
		stuList.add(stu);
		store();
		System.out.println("-----------------------");
		System.out.println("學生信息已增加");
		System.out.println(stu);
		System.out.println("-----------------------");
	}
	
	publicvoiddel(){
		Scannersc=newScanner(System.in);
		System.out.println("請輸入學生學號：");
		Stringid=sc.nextLine();
		intintId=0;
		try{
			intId=Integer.parseInt(id);
		}catch(NumberFormatExceptionex){
			System.out.println("學號輸入有誤，請輸入數字！");
			return;
		}
		Studentstu=find(intId);
		if(stu==null){
			System.out.println("該學號不存在！");
			return;
		}
		stuList.remove(stu);
		store();
		System.out.println("-----------------------");
		System.out.println("學生信息已刪除");
		System.out.println(stu);
		System.out.println("-----------------------");
	}
	
	publicvoidfind(){
		Scannersc=newScanner(System.in);
		System.out.println("請輸入學生學號：");
		Stringid=sc.nextLine();
		intintId=0;
		try{
			intId=Integer.parseInt(id);
		}catch(NumberFormatExceptionex){
			System.out.println("學號輸入有誤，請輸入數字！");
			return;
		}
		Studentstu=find(intId);
		if(stu==null){
			System.out.println("該學號不存在！");
			return;
		}
		System.out.println("-----------------------");
		System.out.println("查找學生信息如下");
		System.out.println(stu);
		System.out.println("-----------------------");
	}
	
	publicStudentfind(intid){
		for(Studentstu:stuList){
			if(stu.id==id){
				returnstu;
			}
		}
		returnnull;
	}
	
	publicvoidmodify(){
		store();
	}
	
	publicvoidforeach(){
		System.out.println("-----------------------");
		for(Studentstu:stuList){
			System.out.println(stu);
		}
		System.out.println("-----------------------");
	}
	
	publicvoidstore(){
		Iteratoriterator=stuList.iterator();
		Filefile=newFile("stuList.txt");
FileWriterfw=null;
BufferedWriterwriter=null;
try{
fw=newFileWriter(file);
writer=newBufferedWriter(fw);
while(iterator.hasNext()){
writer.write(iterator.next().toString());
writer.newLine();//換行
}
writer.flush();
}catch(FileNotFoundExceptione){
e.printStackTrace();
}catch(IOExceptione){
e.printStackTrace();
}finally{
try{
writer.close();
fw.close();
}catch(IOExceptione){
e.printStackTrace();
}
}
	}
	
	publicstaticvoidmain(String[]args){
		StuMgrmgr=newStuMgr();
		while(true){
			System.out.println("請選擇您要進行的操作：");
			System.out.println("1：增加學生信息");
			System.out.println("2：刪除學生信息");
			System.out.println("3：查找學生信息");
			System.out.println("4：修改學生信息");
			System.out.println("5：遍歷學生信息");
			System.out.println("6：退出");
			System.out.println("-----------------------");
			Scannersc=newScanner(System.in);
			Stringop=sc.nextLine();
			if("6".equals(op)){
				return;
			}
			if("1".equals(op)){
				mgr.add();
			}
			if("2".equals(op)){
				mgr.del();
			}
			if("3".equals(op)){
				mgr.find();
			}
			if("4".equals(op)){
				mgr.modify();
			}
			if("5".equals(op)){
				mgr.foreach();
			}
		}
		
	}
}

時間倉促，還有一個modify方法沒實現，留給你自己練手。

㈤ 求java中類似學生信息管理系統中按學號，按姓名排序的代碼

importjava.util.ArrayList;
importjava.util.Collections;
importjava.util.Comparator;
importjava.util.List;

publicclassSort{
	publicstaticvoidmain(String[]args){
		Studentp1=newStudent(1001,"小明",20);
		Studentp2=newStudent(1002,"小紅",21);
		Studentp3=newStudent(1003,"小黑",19);
		List<Student>list=newArrayList<Student>();
		list.add(p1);
		list.add(p2);
		list.add(p3);
		Collections.sort(list,newComparator<Student>(){
			/*
			*intcompare(Studento1,Studento2)返回一個基本類型的整型，返回負數表示：o1小於o2，
			*返回0表示：o1和o2相等，返回正數表示：o1大於o2。
			*/
			publicintcompare(Studento1,Studento2){
				//按照學生的學號進行升序排列
				if(o1.getId()>o2.getId()){
					return1;
				}
				if(o1.getId()==o2.getId()){
					return0;
				}
				return-1;
			}
		});
		write(list);
		System.out.println("---------------------");
		Collections.sort(list,newComparator<Student>(){
			/*
			*intcompare(Studento1,Studento2)返回一個基本類型的整型，返回負數表示：o1小於o2，
			*返回0表示：o1和o2相等，返回正數表示：o1大於o2。
			*/
			publicintcompare(Studento1,Studento2){
				//按照學生的年齡進行升序排列
				if(o1.getAge()>o2.getAge()){
					return1;
				}
				if(o1.getAge()==o2.getAge()){
					return0;
				}
				return-1;
			}
		});
		write(list);
	}

	publicstaticvoidwrite(List<Student>list){
		for(Students:list){
			System.out.println(s.getId()+"	"+s.getName()+"	"
					+s.getAge());
		}

	}

}


publicclassStudent{
	privateintid;
	privateStringname;
	privateintage;
	//構造方法
	publicStudent(intid,Stringname,intage){
		this.id=id;

	}
	publicvoidsetId(intid){

	}
	publicStringgetName(){

	}
	publicvoidsetName(Stringname){
		this.name=name;
	}
	publicintgetAge(){
		returnage;
	}
	publicvoidsetAge(intage){
		this.age=age;
	}
}

㈦ Java實現簡易學生信息管理系統

使用JFileChooser來選擇打開文件， 使用FileInputStream進行讀取文件，FileOutputStream來寫文件 這些沒什麼難度吧。中間的顯示，你就直接用JFileArea就是了，然後設置為自動換行。
