以jinternalframe格式java将参数传递到构造函数中

主页是jFrame的主窗体，上面有一个jDesktopPane。当我单击主页上的jButton Home时，我需要将jinternaframe窗体错误加载到该jDesktoPane上

但是当我试图在jinternalframe中传递参数以使构造函数出错时，主页上出现了一个错误_

我做到了。在这个构造函数中有一个抛出部分，抛出一个异常，如下所示

// This is the code in my Home_Page to perform when the jbutton is clicked. 

 private void homeActionPerformed(java.awt.event.ActionEvent evt) 
 {       
    jDesktopPane1.removeAll();
    error_ e = new error_();
    jDesktopPane1.add(e);
    e.setVisible(true);
    jDesktopPane1.updateUI();
            // TODO add your handling code here:
 }

 //This is the parameter  need to pass through  constructor of jinternalframe form "error_"
 public String eid1;


 Model.JDBC j=new JDBC();
 public error_(String eid) 
 {
    initComponents();
    jLabel3.setText(eid); 
    ResultSet rs;
    try 
    {                     
        rs = j.getData("select mid from employee where eid='"+eid+"'");  

        if(rs.next()==true)
        {
           if(rs.next()==true)
           {
              if(rs.getString(1).equals"sp/cso/it/1")
              {

                    if(eid.equals("sp/cso/it/1"))
                    {}
                    else if(eid.equals("sp/cso/finance/1"))
                    {
                        System.out.println("else if");
                    }
                    else
                    {
                        System.out.println("else");
                    }
              }
           }
        }
        else
        {
            System.out.println("outer else executed");
        }
        } 
        catch (Exception ex) 
        {
            Logger.getLogger(Home_Page.class.getName()).log(Level.SEVERE, null, ex);
        }
}

//This is the code in Home_Page to load the jinternalframe form error_ on to the jDesktopPane in Home_Page

private void homeActionPerformed(java.awt.event.ActionEvent evt) {                                     

      jDesktopPane1.removeAll();
      error_ e = new error_();
      jDesktopPane1.add(e);
      e.setVisible(true);
      jDesktopPane1.updateUI();
        // TODO add your handling code here:
    }

确保您已经完成了“清理并构建”操作，以确保编译了最新的代码。此外，在尝试运行代码之前，请确保没有编译器错误。错误是说需要将字符串传递给_error的构造函数，但您只是调用new _error（）；谢谢你的提示。我会试试的。确保你已经完成了“清理和构建”操作，以确保你已经编译了最新的代码。此外，在尝试运行代码之前，请确保没有编译器错误。错误是说需要将字符串传递给_error的构造函数，但您只是调用new _error（）；谢谢你的提示。我试试看。
