问题 I know that in terms of waiting for web element that isn't in the DOM yet, the most efficient is a fluent wait. So my question is: Is there a way to handle and catch the NoSuchElementException or any exception that fluent wait might throw because the element is not existing? I need to have a boolean method wherein it will give me result whether the element is found or not. This method is quite popular on the web. public void waitForElement(WebDriver driver, final By locator){ Wait<WebDriver>

问题 I have had a similar problem before, but I am looking for a generalizable answer. I am using spark-corenlp to get Sentiment scores on e-mails. Sometimes, sentiment() crashes on some input (maybe it's too long, maybe it had an unexpected character). It does not tell me it crashes on some instances, and just returns the Column sentiment('email) . Thus, when I try to show() beyond a certain point or save() my data frame, I get a java.util.NoSuchElementException because sentiment() must have

问题 Running the Spark bisecting kmmeans algorithm in Zeppelin. //I transform my data using the TF-IDF algorithm val idf = new IDF(minFreq).fit(data) val hashIDF_features = idf.transform(dbTF) //and parse the transformed data to the clustering algorithm. val bkm = new BisectingKMeans().setK(100).setMaxIterations(2) val model = bkm.run(hashIDF_features) val cluster_rdd = model.predict(hashIDF_features) I always get this error though: org.apache.spark.SparkException: Job aborted due to stage failure

问题 Need to assert that there is no such element in the webpage, When tried with fieldValueBox.isDisplayed(); instead of "false" its throwing "NoSuchElementFound" exception. Right now i was using 'try catch' and making decision in 'catch' 回答1: If the element is not on the page, then you will get 'NoSuchElementFound' exception. You can try checking that the number of elements with the locator is zero: private boolean elementNotOnPage(){ boolean elementIsNotOnPage = false; List<WebElement> element

问题 I wrote a program with a separate class but I keep getting the same error right after the user inputs the three sides. The main code is: package interactiveTriangleWithAClass; public class InteractiveTriangleProgramClass { public static void main (String [] args) throws Exception { IAclass nums = new IAclass(); double perimeter; double area; explain(); nums.getNumbers(); perimeter = nums.calcPer(); area = nums.calcArea(); outputResults(nums, perimeter, area); } public static void explain() {

问题 I want to read a text file and put each line in a String (array of Strings). However that requires scanning file twice, one to figure out how many line are there and another time to create an array of strings of that size. but it throws an error and reset method doesn't seem to work. FileReader read = null; try { read = new FileReader("ModulesIn.txt"); //scan through it and make array of strings - for each line Scanner scan = new Scanner(read); while(scan.hasNextLine()){ numOfMods++; scan

问题 I am making a function that returns a Boolean type of whether a String has enough tokens. I do this by using this code: public boolean isEnoughTokens(int tokens, String problem) { try { StringTokenizer token = new StringTokenizer(problem); return true; } catch (NoSuchElementException ) { } } The problem is that I haven't figured out how to catch a No such element exception. I think it's super simple but still didn't figure out how to do it. Thanks, any help will be appreciated!!! 回答1: Here's
