- Python Code: Write a function that takes a single number as an argument: 1) This function should then check whether a number is an even number (2,4,6,8) and raise an exception if otherwise 2) Call this function with an uneven number first without catching the exception and then with catching the exception and printing a warning to the user afterwards Bonus: Do the same as the above but instead implement your solution for prime numbers and call the function with a non-prime numberarrow_forwardThe while loop reads values from input until an integer is read. Complete the exception handler in the while loop to catch an InputMismatchException exception and: Output "Removed unacceptable input for number of cents". End with a newline. Discard the invalid input. Ex: If the input is 20 60, then the output is: 20 cents = 4 nickels Processed one valid input value Ex: If the input is Aya Tia 20 60, then the output is: New JAVA code can only be added after code given: Removed unacceptable input for number of cents Removed unacceptable input for number of cents 20 cents = 4 nickels Processed one valid input value Note: Each value read from input is on one line. /******************************************************************************************************* New Java Code here: test input: Aya Tia 20 60 *******************************************************************************************************/arrow_forwardA finally statement, when used as part of exception handling will be executed... Select one: O a. always, no matter if there is an exception or not. O b. only if the program is going to exit. only if no exception occurred. С. O d. only if an exception is generated, even if the exception is handled by other code.arrow_forward
- Question 22 Write a program that reads integers user_num and div_num as input, and output the quotient (user_num divided by div_num). Use a try block to perform all the statements. Use an except block to catch any ZeroDivisionError and output an exception message. Use another except block to catch any ValueError caused by invalid input and output an exception message. Please do it ONLY in Python Language also inlcude the input and output screenshotarrow_forwardPart 2 Use exception handeling Write a program (CoconutCherry that This program should accept multiple numbers as command line arguments and print those numbers out again space separated but for multiples of 3 print “coconut” instead of the number, for multiples of 7 print “cherry” instead of the number, and for the multiples of both 3 and 7 print “coconut-cherry” instead of the number. For numbers smaller than 1, print “invalid”arrow_forward-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;…arrow_forward
