java.util.NoSuchElementException解决办法

报错代码

public void switchToNewWindow(){
　　　　//得到当前句柄
String currentWindow = driver.getWindowHandle();
    //得到所有窗口的句柄
    Set<String> handles = driver.getWindowHandles();

    //排除当前窗口的句柄，则剩下是新窗口
    Iterator<String> it = handles.iterator();
    while(it.hasNext()){
        if(currentWindow == it.next())  continue;
        driver.switchTo().window(it.next());
    }

}

修改后的代码

    String currentWindow = driver.getWindowHandle();
          //得到所有窗口的句柄
          Set <String> handles = driver.getWindowHandles();
          //排除当前窗口的句柄，则剩下是新窗口
          Iterator<String> it = handles.iterator();
          while(it.hasNext()){
              String it1 = it.next();
              if(currentWindow == it1)  continue;
              driver.switchTo().window(it1);
          }
