,至于后面的，都是页面的东西，查询数据库啊什么的。要设计页面，我就不弄了。
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Test222 {
public static void main(String[] args) throws IOException {
int i, j;
String a;
BufferedReader str = new BufferedReader(
new InputStreamReader(System.in));
System.out.println("请输入学号：");
a = str.readLine();
System.out.println("学号为：" + a);
str = new BufferedReader(new InputStreamReader(System.in));
System.out.println("请输入姓名：");
a = str.readLine();
System.out.println("姓名为：" + a);
}
}
