jTable填充和刷新ArrayIndexOutOfBoundsException

我有下面的SwingWorker填充jTable1。我有執行此任務的按鈕。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，第二和有時第三次執行成功工作。但有時，當我點擊我的按鈕jTable清除，但期望5行（a，a，...線）不來，Java拋出錯誤;

我不明白髮生了什麼事。我也無法調試它，因爲問題隨機發生。有時我執行任務並在屏幕上查看數據5-6次，有時候是1-2次。任何幫助讚賞。謝謝。

我的按鈕是;

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(); 
}

在按鈕事件中檢測到的問題。

fTextFieldSB.getText()和fTextFieldP.getText()返回空字符串，如""所以如果不返回null，所有條件如果在同一時間觸發。我們不想要它。如果條件應該是;

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(); 
}

不確定這是否解決了您的問題，但您無需致電fireTableDataChanged()。這是在addRow內完成的。
