Consider the following test method code fragment, which tests whether a method given invalid input produces the expected exception in response. On which of the following lines should the test return false, indicating that the test has failed? There may be more than one correct answer! try { methodCall(invalidInput); // 1. line after method call } catch (IllegalArgumentException e) { // 2. correct } catch (Exception e) { // 3. incorrect } Group of answer choices 1. line after method call 2. correct 3. incorrect
*This is a handout from my class that I'm having trouble with I tried YouTube videos and I'm still lost please explain the answers as simply as you can and thank you.* A. Look over the following code fragment, give the output: try { method(); System.out.println("After the method call"); } catch (Exception ex) { System.out.println("Exception in main"); } catch (RuntimeException ex) { System.out.println("RuntimeException in main"); } static void method() throws Exception { System.out.println(1 / 0); } B. Write the code to load an array. Use simple I/O (system.out.print, etc.) to get integer values from the user and load the array (loop?). Your code has the potential to generate 2 exceptions: 1) InputMismatch (research this) and 2) IllegalValueException (assume this exists). If the 1st occurs, change the input to be 99, warn the user and continue. The 2nd exception will occur when the user enters a 0; if this occurs, notify the user that a 0 has been entered, and change the input to…
Write a method that will take in a time in 24 hour format (1430) and return the time in 12 hour format (2:30pm). This method should have appropriate exception handling. If an incorrect time is sent as an argument (something out of bounds or 23(#4k in other words garbage), then your method should throw a TimeFormatException which you define. In no case should your method throw an unhandled exception! Show how to test the method to be sure.
Solve In Python Provide Screenshots of Input and Ouput For this lab, you will modify your Lab 7 to make several improvements to the getter/settermethods. Instead of having them return True/False, modify each one to throw an exception ifinvalid data is passed.Modify these methods in the following way:• add_hours()o If the number of hours being added is less than 0, throw an exception• add_sales()o If the amount of sales being added is less than 0, throw an exception• set_employee_number()o The employee number must be an integer. If the given input is not an integer,throw an exception• set_office_number()o If the office number given is less than 100 or greater than 500, throw anexception.• set_name()o If the given name is empty, throw an exceptiono Any of the following characters should be removed from the name: ‘_’, ‘.’, ‘-‘ (Underscore, period, and dash)• set_birthdate()o If the given value for the month is less than 1 or greater than 12, throw anexceptiono If the given value for the…
Using JavaFX, create a simple calculator application, like the following: The operators is ( + : " addition process" , -:subtraction process", *:"multiplication process" , /:"division process" , C : "Clear" , H: "History"); Validate that the first number and second is a numeric value if it is not throwing an exception. When clicking the operators (+, -, *, /): the result will display at the bottom, and stored in history. When clicking C, clear the first, second number and the history. When clicking H, the history will display at the bottom. When the user click / and the second number is 0 throw an arithmetic exception.
Q# When JUnit testing with exceptions, which of the following is true? Group of answer choices A successful test happens whenever an exception is not thrown. Exceptions and tests should not be used together. A failed test results when you catch an exception on valid input. If you give an illegal argument to a method the JUnit test will fail. Q# When you want a method to return nothing, what do you put for the return type? Group of answer choices boolean false void null Q# Which of the following statements are true? Group of answer choices All of the options are true. Methods can take multiple primitives as arguments. Methods can take objects of other classes as arguments. A method for a class can take an object of that class as an argument. Q# What does Java guarantee is part of every class? Group of answer choices AtoString() A set of Getter methods to retrieve class variables. A method to get the binary representation of the class. A set of private class…

What is the difference between using @Test(expected = TypeOfException) and using try/catch when testing if a method or constructor properly returns an exception? A. They do the same thing. B. @Test(expected = ...) is the proper way to unit test in java, and try/catch should only be used when unit testing in Python. C. @Test(expected = ...) will give a passing test as soon as one exception of the proper type is thrown and then stop the test, but using try/catch will allow you to test many examples in the same test and will only stop after running all examples or reaching a fail() or an assert statement that fails. D. We should never use try/catch when unit testing, otherwise we will catch the exception and then won't know if it is actually thrown.
