- Rules: Corner cases. Throw the specified exception for the following corner cases: Throw an IllegalArgumentException if the client calls either addFirst() or addLast() with a null argument. Throw a java.util.NoSuchElementException if the client calls either removeFirst() or removeLast when the deque is empty. Throw a java.util.NoSuchElementException if the client calls the next() method in the iterator when there are no more items to return. Unit testing. Your main() method must call directly every public constructor and method to help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. Your implementation must achieve the following worst-case performance requirements: A deque containing n items must use at most 48n + 192 bytes of memory, not including the memory for the items themselves. Each deque operation (including construction) must take constant time. Each iterator operation (including construction) must take…PLZ help with the following IN JAVA If a method throws an exception, and the exception is not caught inside the method, then the method invocation: terminates transfers control to the catch block transfers control to the exception handler none of the above(Please use JAVA) Create custom exception and implement exception handling Create the following classes based on the UML Class diagram: - Employee - InvalidUserDetailException - EmployeeValidation-uses the custom InvalidUserDetailException class. This class contains an instancemethod validateInput() which will validate the employee details (name, age & gender) based on the specified criteria. * If employee details are within the criteria, employee details will be outputted in the console. * If employee details are not within the criteria, InvalidUserDetailException will be thrown with a message informing user that employee detail inputted is invalid. Create Employee Main class which will contain the main() method main() method will allow user to input employee name, age and gender. Calls validateInput() to validate the employee details.
- 10.8 LAB: Step counter - exceptions A pedometer treats walking 2,000 steps as walking 1 mile. Write a steps_to_miles() function that takes the number of steps as a parameter and returns the miles walked. The steps_to_miles() function throws a ValueError object with the message "Exception: Negative step count entered." when the number of steps is negative. Complete the main() program that reads the number of steps from a user, calls the steps_to_miles() function, and outputs the returned value from the steps_to_miles() function. Use a try-except block to catch any ValueError object thrown by the steps_to_miles() function and output the exception message. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print(f'{your_value:.2f}') The code I have so far(Python Code): import sysdef steps_to_miles(steps): try: if steps<0: raise ValueError('Exception: Negative step count entered.') return…Java Questions - (Has 2 Parts).

- C++ D.S. Malik Exercise 14-4 Write a program that prompts the user to enter time in 12-hour notation. The program then outputs the time in 24-hour notation. Your program must contain three exception classes: invalidHr, invalidMin, and invalidSec. If the user enters an invalid value for hours, then the program should throw and catch an invalidHr object. Follow similar conventions for the invalid values of minutes and seconds.The following class maintains an account balance and returns a special error code. public class Account { private double balance; // returns new balance or -1 if error public double deposit(double amount) { if (amount > 0) balance += amount; else return -1; // Code indicating error return balance; } } Rewrite the class so that it throws appropriate exception instead of returning -1 as an error code. Write test code that attempts to depositChallenge 1: Division.java You have to implement a Division class that divides two numbers given by the user. The program should handle exceptions that could be thrown during operation: If the second number is 0 If any of the numbers is not a valid number, such as a letter.
