Write a program that converts a time from 24-hour notation to 12-hour notation. To make the solution easier, a requirement is imposed on the input: It must be in xx:xx format, i.e. it must have two digits, a colon, and then another two digits. Define an exception class called TimeException. If the user enters an illegal time, like 10:65, or even gibberish, like 8&*68, your program should throw and handle a TimeException. Test your program with the file "times.txt" as input and store the result in the file "result.txt"

Write a program that prompts the user to enter a length in feet and then enter a length in inches and outputs the equivalent length in centimeters. If the user enters a negative number or a non-digit number, throw and handle an appropriate exception and prompt the user to enter another set of numbers.
Your error message should read A non positive number is entered and allow the user to try again.
Format your output with setprecision(2) to ensure the proper number of decimals for testing!
Write a class TimeOfDay that uses the exception classes defined in the previous exercise. Give it a method setTimeTo(timeString) that changes the time if timeString corresponds to a valid time of day. If not, it should throw an exception of the appropriate type. [Java]

- Write a method that will take in a time in 24 hour format (1430) and return the time in 12 hour format (2:30pm). This method should have appropriate exception handling. If an incorrect time is sent as an argument (something out of bounds or 23(#4k in other words garbage), then your method should throw a TimeFormatException which you define. In no case should your method throw an unhandled exception!

Use another except block to catch any ValueError caused by invalid input as a variable and output "Input Exception: " followed by the exception message from the variable.

A. They do the same thing. B. @Test(expected = ...) is the proper way to unit test in java, and try/catch should only be used when unit testing in Python. C. @Test(expected = ...) will give a passing test as soon as one exception of the proper type is thrown and then stop the test, but using try/catch will allow you to test many examples in the same test and will only stop after running all examples or reaching a fail() or an assert statement that fails. D. We should never use try/catch when unit testing, otherwise we will catch the exception and then won't know if it is actually thrown.arrow_forward
