求与数据库有关的问题

Question

我做了两个界面为:searchclass和studentInfoClass,我想在studentInfoClass中显示,在searchclass查找到的内容.可是在studentInfoClass 中不能显示,求高手指教.代码如下:
 studentInfoClass sic=new studentInfoClass();
      if(jrb1.isSelected())
      {
       searchNumber1=jtf1.getText();
       System.out.println("num1");
       sql="select * from stuTable where Num='" + searchNumber1 + "'";
       rs=DB.getResult(sql);
       while(rs.next())
       {
           sic.jTextField1.setText(rs.getString(1));
           sic.jTextField2.setText(rs.getString(2));
           sic.jTextField3.setText(rs.getString(3));
           sic.jTextField4.setText(rs.getString(7));
           sic.jTextField5.setText(rs.getString(4));
           sic.jTextField6.setText(rs.getString(5));
           sic.jTextField7.setText(rs.getString(6));
       }
数据库连接没有问题,只是查到的值无法传到studentInfoClass
