Java 下拉列表中的选项不是webdriver读取

场景：比较旧月份和新月份，如果两者不相等，则下载新月份的报告

以下是网站链接：

它读取所有，并忽略所有选项读取2016年1月和下载报告，直接跳到11月，而不是下载12月报告。静态旧月我从一个txt文件，即：2015年10月采取

代码如下：

WebElement selectElement = driver.findElement(By.id("ReportViewerControl_ctl04_ctl03_ddValue"));
             //Getting the count of the values in the drop down list 
              Select listBox = new Select(selectElement);
              int size1 = listBox.getOptions().size();
              //prints the size to the console
              System.out.println("Total no. of months in the drop down is:"+ size1);

          System.out.println("The old month is: " + oldMonth);
          //String newMonth ="";
          //listBox.selectByIndex(3);
          String newMonth ;


              for (int i = 1; i < size1; i++) {
                  WebElement mSelectElement = driver.findElement(By.xpath(".//*[@id='ReportViewerControl_ctl04_ctl03_ddValue']"));
                  List<WebElement> optionsList = mSelectElement.findElements(By.tagName("option"));
              WebElement element = optionsList.get(i);
              newMonth = element.getText();

              //Message that prints the new month
              System.out.println("The new month is:"+newMonth);

          /*Condition to check if the New month is equal to Old month, if it is not equal then proceeds
           * to download that particular month data or else breaks the loop
           */
              if (!oldMonth.equals("All") & !newMonth.equals("All")) {
          if (oldMonth.equals(newMonth)) {
              System.out.println("No new months are available to download");
               Wait(10000);
              driver.close();
              break;
          }//else if (i==1 || (oldMonth.equals(newMonth))) {
          //else if (i==1 & !(oldMonth.equals(newMonth))) {
         else if (!(oldMonth.equals(newMonth))) {   
              download report

}

它必须返回到for循环

请确认从何处比较旧月份和新月份。我告诉右静态设置一个txt文件=2015年10月为月份，从txt文件我将比较字符串。新月份将从所选内容中的所有内容开始。全部=2015年10月，1月=2015年10月等等。我的问题是在读了1月之后，应该读12月，但跳到11月。这就是问题所在。我不想把旧的月份当作十二月。
