Exercise: Handling Exceptions

Problem statement

In the below handleInput function, different kinds of user inputs can lead to exceptions that might break our program execution. Your task is to catch all possible exceptions and display appropriate messages to the user.

• If the user input for a number is not a correct number, then toInt throws NumberFormatException. In such a case, you should print “Invalid input:” and an error message.

• If the user input is a number, but the second number is zero, then ArithmeticException is thrown. In such a case, you should print a “Division by zero” message.

• If the user input is an operator that is not supported by the calculator, then IllegalOperatorException is thrown. In such a case, you should print “Illegal operator:” and the operator that was entered by the user.

Instructions

In the provided code, the handleInput function manages user input. Your task is to implement exception handling within the handleInput function to address the specified cases. Additionally, wrap the function call with a try-catch block in the main function to ensure proper handling of any potential exceptions.

The actual output when running the provided code should be as follows:
