jTable填充和刷新ArrayIndexOutOfBoundsException

我有下面的SwingWorker填充jTable1。我有执行此任务的按钮。jTable填充和刷新ArrayIndexOutOfBoundsException

public class WorkerTime extends SwingWorker<Void, Void> { 

    protected Void doInBackground() throws Exception { 

     DefaultTableModel model1 = (DefaultTableModel) jTable1.getModel(); 
     model1.setRowCount(0); 

      for (int i = 0; i < 5; i++){ 

       model1.addRow(new String[]{"a","a","a","a","a","a","a","a","a","a","a"}); 
       model1.fireTableDataChanged(); 

      } 

    return null; 
    } 

    public void done() { 

    } 

}

第一，第二和有时第三次执行成功工作。但有时，当我点击我的按钮jTable清除，但期望5行（a，a，...线）不来，Java抛出错误;

我不明白发生了什么事。我也无法调试它，因为问题随机发生。有时我执行任务并在屏幕上查看数据5-6次，有时候是1-2次。任何帮助赞赏。谢谢。

我的按钮是;

if(radioButtonLF.isSelected() || radioButtonLF2.isSelected() || radioButtonT.isSelected() || radioButtonLH.isSelected()){ 
    WorkerTime workerTime = new WorkerTime(); 
    workerTime.execute(); 
} 
if(!fTextFieldSB.getText().equals(null)){ 
    WorkerSB workerSB = new WorkerSB(); 
    workerSB.execute(); 
} 
if(!fTextFieldP.getText().equals(null)){ 
    WorkerPB workerPB = new WorkerPB(); 
    workerPB.execute(); 
}

在按钮事件中检测到的问题。

fTextFieldSB.getText()和fTextFieldP.getText()返回空字符串，如""所以如果不返回null，所有条件如果在同一时间触发。我们不想要它。如果条件应该是;

if(radioButtonLF.isSelected() || radioButtonLF2.isSelected() || radioButtonT.isSelected() || radioButtonLH.isSelected()){ 
    WorkerTime workerTime = new WorkerTime(); 
    workerTime.execute(); 
} 
if(!fTextFieldSB.getText().equals("")){ 
    WorkerSB workerSB = new WorkerSB(); 
    workerSB.execute(); 
} 
if(!fTextFieldP.getText().equals("")){ 
    WorkerPB workerPB = new WorkerPB(); 
    workerPB.execute(); 
}

不确定这是否解决了您的问题，但您无需致电fireTableDataChanged()。这是在addRow内完成的。
