问题 If I close one scanner object and make a new one and try to read some more input, I'm getting the NoSuchElementException exception. My code works fine but it gives me a warning if I don't close the scanner. However, if I close it to get rid of the warning, I also close System.in ... How do I avoid this? Also, are there any consequences of not closing the scanner? EDIT: Here's my code: This is the NameAddressExists() method: public void NameAddressExists() { System.out.println("Enter name");

问题 I'm using VS2012 and i want to customize my selenium tests. For example, when test fails, i want to show the text The page loaded too long - unable to login + original message instead of showing only this: OpenQA.Selenium.NoSuchElementException: Unable to find element with id == loginElementID . Is it possible? How and when to use Assertions when UI testing? That would make my tests more understandable and informative. var wait = new WebDriverWait(driver, new TimeSpan(0, 0, 0, 8)); wait

问题 In the below code I have used two scanners, One in performAction() method and one in getTicketNumber() method. I have used try with resources and once when I go into getTicketNumber() method, it works fine and once when the control returns back and comes to performAction() I am getting No Such Element Exception when it executes the scanner.nextInt() line. I wanted to continue this process until I press exit. I guess it is due to the use of multiple scanners since if I don't go into

问题 I am trying to create a simple small program that will ask for a positive int and won't crash or close until it has received a positive int from the user. However my program keeps crashing, and reporting the error NoSuchElementException, when it calls the method with Scanner in it more than once. I will be using the fundamentals of this program to help some other things I am working on. Here is my current code; import java.util.InputMismatchException; import java.util.Scanner; public class
