2. (Optional) Improve the program to avoid the run-time error "ArithmeticException: / by zero". So when a user clicks the "Divide" button, the program should run a test to check whether the second number is zero or not. Then only if the second number is not zero, it will perform the division operation, and otherwise it should display the message "Divisor cannot be zero". KI Simple Calculator First Number 20 Second Number: 0 Result Divisor cannot be zero Add Subtract Multiply Divide 3. (Optional) Improve the program to avoid the run-time error "NumberFormatException: empty String". So when a user clicks any button, the program should run a test to check whether both numbers has been entered not. Then only if both numbers has been entered, it will perform the operation, and otherwise it should display the message "Enter a number".
