Java: An Introduction to Problem Solving and Programming (8th Edition)
- Challenge 2: InvalidNumbers.java Write a program InvalidNumbers that asks the user to enter a positive integer. The program will warn the user if a valid integer is not entered using the InputMismatchException and ask to enter again. The program should also throw an exception if the user enters negative numbers. Write the program and test it using negative numbers, doubles, and very large numbers.arrow_forwardC++ You did this way back in Unit 1! But now all of your RomanNumber code is wrapped up in a class, so the "main" program is short and sweet. As before, write a program that accepts entries from the user. If it's an integer, convert to Roman Number and display. If it's a Roman Number, convert to integer and display. If it's neither, thrown an exception and continue to process The action to take here will be to display an error message If the entry is 0 or O (The digit 0 (zero) or the letter O) exit and state how many conversions were done of each type (integer to Roman and Roman to integer) and how many exceptions were thrown. As I said, the main program will be short and sweet. Provide your .cpp code and a screen shot of your program in action. Enter twelve conversions - four integer to Roman, four Roman to integer, and two of each in which the input is invalid so that I can see the exceptions. The thirteenth and final entry will be 0 or O.arrow_forwardtrue or false. language is javaarrow_forward
- Write an application that throws and catches an ArithmeticException when you attempt to take the square root of a negative value. Prompt the user for an input value and try the Math.sqrt() method on it. The application either displays the square root or catches the thrown Exception and displays an appropriate message NB:ALSO SHOW OUTPUTarrow_forwardWrite an application that throws and catches an ArithmeticException when you attempt to take the square root of a negative value.

- Write a program that calculates an adult's fat-burning heart rate, which is 70% of 220 minus the person's age. Complete fat_burning_heart_rate() to calculate the fat burning heart rate. The adult's age must be between the ages of 18 and 75 inclusive. If the age entered is not in this range, raise a ValueError exception in get_age() with the message "Invalid age." Handle the exception in_main_ and print the ValueError message along with "Could not calculate heart rate info." Ex: If the input is: 35 the output is: Fat burning heart rate for a 35 year-old: 129.5 bpm If the input is: 17 the output is: Invalid age. Could not calculate heart rate info.arrow_forwardI need to know how to do this in python: Write a program that calculates an adult's fat-burning heart rate, which is 70% of 220 minus the person's age. Complete fat_burning_heart_rate() to calculate the fat burning heart rate. The adult's age must be between the ages of 18 and 75 inclusive. If the age entered is not in this range, raise a ValueError exception in get_age() with the message "Invalid age." Handle the exception in __main__ and print the ValueError message along with "Could not calculate heart rate info."

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('{:.2f}'.format(your_value)) Ex: If the input of the program is: 5345 the output of the program is: 2.67 Ex: If the input of the program is: -3850 the output of the program is: Exception: Negative step count entered.arrow_forwardIf an exception is thrown, how do you get out of break mode?arrow_forward
