The problem is resolved.
问题解决了。
The place where I was declaring currentWindowHandle was after clicking and it takes the new window as the Current Window handle.
我声明 currentWindowHandle 的地方是在单击之后，它将新窗口作为当前窗口句柄。
I just moved below statement to before the new window click event.
我只是将下面的语句移到新窗口单击事件之前。
String currentWindowHandle=driver.getWindowHandle();
Thanks all for your time and Help.
感谢大家的时间和帮助。

It causes because page took long time to load , you need add additional line to your chromedriver option.
这是因为页面需要很长时间才能加载，您需要在 chromedriver 选项中添加额外的行。
System.setProperty("webdriver.chrome.driver","E:\selenium\chromedriver_2.41\chromedriver.exe");
//mention the below chrome option to solve timeout exception issue
ChromeOptions options = new ChromeOptions();
options.setPageLoadStrategy(PageLoadStrategy.NONE);
// Instantiate the chrome driver
driver = new ChromeDriver(options);
