. AnInputMismatchExceptionisthrownbyaScannertoindicatethatthetokenretrieved does not match the pattern for the expected type, or that the token is out of range for the expected type. For example, if you use the nextDouble to read a token that is not of the type double.

Write a program that prompts the user to enter a mathematical formula (e.g., 4.3 + 5.1) and then displays the result. Your program should prompt the user to try again if the input has an invalid number or invalid operator (i.e., valid operators are: +, -, /, and *). Assume the user enters spaces between the operands and the operator. Read the numbers using the Scanners nextDouble method, and the operator using the next method.

Hints: Use a while loop that will keep prompting the user for input as long as it is invalid. Use a try-catch statement to check for the numbers validity. Use a selection statement (e.g., if, switch, etc.) to check for the operators validity.
