When testing exception cases with assertThrows, what is the best practice? A. We need to check the state of the object after the assertThrows to ensure the post-conditions of the exception are as intended. B. Trick question! We do not test exception cases! C. We should assert that the assertThrows checks for the most general (or highest-level) exception possible D. All of our exception tests should be in one single test method.

The Third program needs to handle data from files (open, read/write, delete to handle data). It uses exception handling – try and except to catch and handle exceptions. Follow coding standards, naming conventions for variables and functions. Students will be asked to explain the working of their program and the logic they’ve used.

QUESTION 6 What would not cause an exception to be thrown from a cast? (Choose all that apply) A. If precision is lost due to the cast (example: double to int) B. If the object is cast to a superclass of its current type C. If the object was never instantiated as the object that it is being cast to or one of its subclasses D. If the object being cast is null

Design and implement a program that creates an exception classcalled StringTooLongException, designed to be thrown when astring is discovered that has too many characters in it. In the maindriver of the program, read strings from the user until the userenters "DONE". If a string that has too many characters (say 20) isentered, throw the exception. Allow the thrown exception toterminate the program

Please can you answer these three questions

-Modify your parameter constructors to call your set methods. This will cause validation of the parameter.-Create an exception class named TractorException.-Modify your setters to throw TractorException if invalid values are passed in. You may also need to add a throws clause to your parameter constructors. This way we will not have any print methods in our Tractor object defining class-Modify your main method to try and catch exceptions. It should catch TractorExceptions and general Exceptions and display an appropriate message   import java.util.*; class TestException {     public static void main(String s[]) {            Scanner scanner = new Scanner(System.in);                boolean valid=false;                // validation loop        while (!valid) {           try {               System.out.println("Enter integer:");               int number = scanner.nextInt();  // may throw an exception               System.out.println("You entered "+ number);               valid=true;…

pls help asnwer this code in c++

In Java, please comment and comment with output please This programming assignment involves learning about some of the common exceptions that occur in Java programs. Consider the following exception types: NullPointerException ArrayIndexOutOfBoundsException ClassCastException IllegalArgumentException Research what each exception type means and the conditions under which each occurs (i.e., is thrown). Write programs that demonstrate each type of exception being thrown (one program per exception) and provide a screen capture of the output. Name your programs as follows: NullPointerExceptionThrown, etc. Then, write a program that catches each type of thrown exception and display an error message indicating some of the details as to what that exception is. Write one program per type of exception. Name your programs as follows: NullPointerExceptionCatch, etc.

this is a java program code please do the code what in the question says and please follow what in the question says and dont copy or plagarise from other sources
