我在for循环中使用setValue方法来填充我在Jtable中的2列中的1列，其他列由用户填写，当他/她按下按钮时我想要检索输入的所有项目数组。
如果我离开＆＃39;那么我的代码就完美了。输入的最后一个单元格然后点击按钮。
但是如果最后一个输入单元格仍处于焦点状态，那么＃p;我点击按钮时出现此错误。

我试过看了很多教程，但似乎都没有遇到同样的问题。请帮忙
抱歉无法发布我的代码，因为无法正确格式化。
input=new Double[list.size()];
jTable_InputMeasurments.getRowCount()-1);
for(int i=0;i<list.size();i++){
String kgDM=(String) jTable_InputMeasurments.getModel().getValueAt(i, 1);
double kgDMw=Double.parseDouble(kgDM);
input[i]=kgDMw;
}
