java - 我在 Swing Worker 中遇到编译错误？

Question

我编写了一个扩展 SwingWorker 的类。我编写了重写函数:doInBackground、done 和 process，但由于某种原因我收到编译错误:

The method process(List) of type BillImportAnalyzerGUI.Task must override or implement a supertype method

这是我的类(class):

  private class Task extends SwingWorker<Void, Void>
  {
    @Override
    public Void doInBackground()
    {
      try
      {
        generateReport(BillImportId.getText());
      }
      catch (InterruptedException e)
      {
      }
      catch (Exception e)
      {
      }

      publish();

      return null;
    }

    @Override
    protected void done()
    {
      try
      {
        jLabel6.setText("Generated Report");
      }
      catch (Exception ignore)
      {
      }
    }

    @Override
    protected void process(List<String> chunks)
    {
      jLabel6.setText("Generating Report");
      jProgressBar1.setVisible(true);
    }
  }

Answer 1

问题是您正在扩展 SwingWorker<Void,Void>但您将该方法声明为 process(List<String> chunks) .

您应该扩展SwingWorker<Void,String>在这种情况下。
