问题之三个输入框

问题描述：

等价类划分中的EditBox问题的升级版！！！三个输入框~

三个输入框，都只能允许1到6个英文字符或数字，按OK结束。

等价类划分：

根据有效或无效的等价类设计的测试用例：

源代码如下：

  1 package test;
  2
  3 import javafx.application.Application;
  4 import javafx.event.ActionEvent;
  5 import javafx.event.EventHandler;
  6 import javafx.scene.Scene;

  9 import javafx.scene.layout.AnchorPane;
 10 import javafx.scene.layout.StackPane;
 11 import javafx.scene.text.Text;
 12 import javafx.stage.Stage;
