求完整java代碼一份 學(xué)籍管理系統(tǒng) 。 不需要高大上的功能， 基本的增刪改查登錄注冊(cè)退出什么的就好。

測(cè)試與結(jié)果：

計(jì)算機(jī)維護(hù)管理系統(tǒng) java的代碼

你這個(gè)程序不算大。

但有很多地方的信息很不明確。比如說：你的數(shù)據(jù)庫系統(tǒng)是什么？表結(jié)構(gòu)？

如果說你想就靠分白拿這么多功能的JAVA代碼應(yīng)該也是不可能的。

建議你一個(gè)模塊一個(gè)模塊的問。在別人的幫助下你再想辦法自己整合一下。

這樣的題一般大學(xué)做畢業(yè)設(shè)計(jì)應(yīng)該可以了。做出來都可以賣錢的!!

java的代碼分享網(wǎng)站有哪些？

1. java2s

這個(gè)網(wǎng)站非常好，分成三大類，分別是Example 、Products 、 Articles ，每個(gè)大類下又分別設(shè)許多小類，還有搜索功能，這樣查找起來非常方便。。比如，如果要學(xué)習(xí)SWT/JFace，只要把Example下的SWT JFace Eclipse 研究一下也就可以了。另外，這個(gè)網(wǎng)站還有JavaScript DHTML 、 C# / C Sharp 、 C / ANSI-C 、 SQL / MySQL 等類?？傊?，非常好。

2. codeZoo

這是O'Reily旗下的，除了Java之外，還有Ruby、Python。

3. Java學(xué)習(xí)源代碼檢索系統(tǒng)

難得看見國產(chǎn)的，好歹也要支持一下，分類也算清楚。

4. Koders

是個(gè)綜合查詢的網(wǎng)站，不過它好像是從代碼中查找關(guān)鍵詞，包含的語言挺多的。

5. Resources for Java server-side developers

確切的說，它是一個(gè)資源收集的網(wǎng)站，代碼查詢并不多。不過它分類相當(dāng)細(xì)，如Articles、Books、Examples、Extensions、Frameworks等類，你可以輸入Spring或Hibernate作為關(guān)鍵詞搜索一下看看。

第五個(gè)：

f.add(p);

f.setSize(400,300);

f.setLocation(300,250);

f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

f.setVisible(true);

}

}

第六個(gè)：

import java.sql.Connection;

import java.sql.ResultSet;

import java.sql.Statement;

public class Student {

int age;

public Student(){}

}

catch(Exception e){

return b;

}

public boolean selectByStuNo(String stuNo)throws Exception{

Statement statement = con.createStatement();

String sql = "select * from student where stuNo =" + stuNo;

ResultSet rs = statement.executeQuery(sql);

}

rs.close();

statement.close();

}

數(shù)據(jù)庫你自己弄吧，我沒時(shí)間弄了！初學(xué)得多動(dòng)手哦
