使用I/O直接将数据保存在记事本中吧，估计这是最简单的。如果用数据库，30分有点太少了。对于查询的的功能可以用正则表达式将整个记事本的内容进行查找。你可以根据你的要求改一改,用于保存信息的类：import 。FileWriter;import 。
IOException;public class Io { public static void main(String[] args) { String dir = "d:/index。text";// 文件保存路径 try { FileWriter fw = new FileWriter(dir); String s = "张三 女 040911111 日语051班 山东济南人" + "\r\n"; String s2 = "李四 男 050811111 日语052班 山东德州人" + "\r\n"; fw。
write(s); fw。write(s2); ose(); } catch (IOException e) { // TODO Auto-generated catch block intStackTrace(); } }}用于查询的类：import 。
BufferedReader;import 。FileReader;import 。IOException;import 。Reader;public class Lookup { public static void main(String[] args) throws IOException { Reader dir; dir = new FileReader("d:/index。
text"); BufferedReader fr = new BufferedReader(dir); String s ; while ((s= adLine()) != null) { if( ntains("040911111"))//查找号为040911111的学生信息，如果存在打印出来 intln(s); } ose(); }}。
会，但是一看这分，只能发个言，灌水一下就走人
说实在的要写全了，就是你给一百分我也不见得愿意帮你写，实在太多了啊，不过我这有个以前的例子真好有点适合你的，和你的基本差不多，你稍微该点数据就可以了package xiangnu;import t。BorderLayout;import t。
