Java 如何在从第二个窗口切换到第三个窗口时通过selenium webdriver处理多窗口

我正在尝试从第二个窗口切换到第三个窗口。但无法处理第三个窗口。请有人帮助我解决此问题。 我使用了比较窗口标题的逻辑，但它不起作用。 代码=======================

你能总结一下你正在尝试自动化的具体手动步骤吗？ThanksOn站点>>菜单上的CLk>>我们的标签和品牌，然后在Abbey road上的CLk研究>>网站上的CLk按钮>>现在新选项卡打开，在新窗口上，单击店铺链接--在Abbey road store打开的新窗口>>当我无法处理此Abbey road store选项卡时，单击登录。

Parent Window ID is : CDwindow-4663fceb-a7a3-4d72-8236-510790729377
Now Total Windows : 2

Child 1 Window ID is : CDwindow-c5de0d53-06ab-4e27-9516-b9c7a130cd5f
Now Total Windows : 3
Child 2 Window ID is : CDwindow-e88831ba-6b53-449c-a2f2-b8ba341c8433
