我有一个我在NetBeans中创建的Java FXML应用程序，到目前为止所有内容都按预期工作，但随着我开始改进所有内容并使其更加用户，我遇到了这个特定代码的问题：
@FXML
private Label differenceResultsLabel;
@FXML
private Label responseTimeResultsLabel;
public boolean checkForResponseTime(double[] responseTimeArray)
{
int arrayLength = responseTimeArray.length;
double maxThreshold = Double.parseDouble(maxResponseTime.getText());
for (int i=0; i < arrayLength ; i++)
{
if (responseTimeArray[i] > maxThreshold)
{
System.out.println("Response Time beyond threshold!");
responseTimeResultsLabel.setTextFill(Color.RED);
responseTimeResultsLabel.setText(Arrays.toString(responseTimeArray));
return false;
}
}
System.out.println("All response times OK");
responseTimeResultsLabel.setTextFill(Color.GREEN);
responseTimeResultsLabel.setText(Arrays.toString(responseTimeArray));
System.out.println("Hello?");
return true;
}
请注意，FXMLDocument.fxml文件中的标签已经是fx：id'd。 但是，当我运行程序时，标签不会改变（即使我得到其他行（Hello？和所有响应时间都可以）。
这是输出注意：我删除了一系列SYSTEM.OUTPRINTLN以使其更易于阅读：
