import java.util.*;
public class Test {
    public Test(){
    }
    public static void main(String[] args){
        DataBase database = null;
        Connection con = null;
        try {
            database = new DataBase();
            con = database.getConnection();
        } catch (Exception ex) {
        }
        Student student = MarkDB.getMark(con, "032503");
        if(student == null)
        	System.out.println("您所指定的学号不存在!");
        else{
        	System.out.println(student.getID() + " " + student.getName() + " "
        			                                 + student.getGender());
