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! Show how to test the method to be sure.

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" File times.txt: 00:00 12:00 12:01 11:59 23:59 24:00 10:65 3:23 1145 8&*68 File result.txt: # 24-hour 12-hour -------------------------------------------- 1 00:00 12:00 AM 2 12:00 12:00 PM 3 12:01 12:01 PM 4 11:59 11:59 AM 5 23:59 11:59 PM 6 24:00 Time Exception 7 10:65…
Solve In Python Provide Screenshots of Input and Ouput For this lab, you will modify your Lab 7 to make several improvements to the getter/settermethods. Instead of having them return True/False, modify each one to throw an exception ifinvalid data is passed.Modify these methods in the following way:• add_hours()o If the number of hours being added is less than 0, throw an exception• add_sales()o If the amount of sales being added is less than 0, throw an exception• set_employee_number()o The employee number must be an integer. If the given input is not an integer,throw an exception• set_office_number()o If the office number given is less than 100 or greater than 500, throw anexception.• set_name()o If the given name is empty, throw an exceptiono Any of the following characters should be removed from the name: ‘_’, ‘.’, ‘-‘ (Underscore, period, and dash)• set_birthdate()o If the given value for the month is less than 1 or greater than 12, throw anexceptiono If the given value for the…
Derive exception classes from the class you wrote in the previous exercise. Each new class should indicate a specific kind of error. For example, InvalidHourException could be used to indicate that the value entered for an hour was not an integer in the range of 1 to 12. (Also the previous answer was not preferd from the teacher cause its not simple and use def which we arent taken it)
Take two integers from the user, Write a program in Java to divide a number by another. Point to be NOTED: User may give "string or o“ as divider intentionally or by mistake. You must handle all types of exception, But the program should not stop if there is any kind of error or exception. Your program should provide as many chances as user need to complete the calculation. The program will immediately exit after successfully dividing the 1st number by 2nd number.
We are asked to add an exception to the game. Please see below. For this part of the assignment you can start by creating your own exception in a file named NumberGuesserIllegalStateException.java, with this code: public class NumberGuesserIllegalStateException extends Exception { public NumberGuesserIllegalStateException(String errorMessage) { super(errorMessage); } } Next modify your code so that the higher and lower methods of both the NumberGuesser and RandomNumberGuesser should throw the exception if there are no more remaining numbers to guess. You might be able to achieve this by adding the logic to your NumberGuesser and letting RandomNumberGuesser inherit the behavior. Or you might need to add the logic to both classes. It will depend on your implementation. Finally add a try-catch block to your number guessing game so that the user is notified if the user cheats.
Assume you are considering writing a method and are deciding what should happen when given input that is outside of perfect input. Which of the following is not a way to handle this? Group of answer choices 1. Use better JUnit testing 2. Throw an exception 3. Try to reasonably auto-correct 4. Prevent the error
Foundation in java Please provide a basic exception code. Do not use input, output. Please provide code and explain. Thank you. Write the Java code for the following: Write the InvalidGradeException class that will be used below. Write the Java program that reads an integer grade from a user and checks that it is valid (between 0 and 100). If it is invalid an InvalidGradeException will be thrown, stating what the invalid grade is. This will be caught in the main( ) method which will write a message about the invalid grade. If the grade is valid, it is written to the monitor..
Programme Leader of ITMB wants to check whether the student number and GSM number entered by the student for the programming contest is valid or not. Write a Java program to read the Student ID and GSM Number of a student. Use a method called ValidityDetails () for checking the validity of details entered. If the Student ID doesn’t start with the characters ST and contains more than 6 letters or if the Mobile Number does not contain exactly 8 digits, throw a user defined exception InvalidDetailsException. If the details entered are valid, display the message ‘”correct details are entered!!!” otherwise display “Entered invalid details!!!!”
Write a java program called AddressBook which allows the user to enter names, phone Numbers and email address and saves them into a text file called addresses.txt. Then have the user enter the last name and have the program read back that person's contact info. Exception handling should be used to display an error message if the program is unable to open the file or the person being searched for does not exist. You may use the code examples on pages 622-623 for a similar example to how your program should be written. For example: Welcome to Address Book! Enter last name, first name, phone number, and email address Enter EOF to end input Doe John 555-123-4567 jdoe@gmail.com Stevens John 845-688-6017 stevensj@gmail.edu > EOF Enter last name to search: Doe Record Found: John Doe 555-123-4567
in java Write a program that reads integers userNum and divNum as input, and output the quotient (userNum divided by divNum). Use a try block to perform the statements. Use a catch block to catch any ArithmeticException and output an exception message with the getMessage() method. Use another catch block to catch any InputMismatchException and output an exception message with the toString() method. Note: ArithmeticException is thrown when a division by zero happens. InputMismatchException is thrown when a user enters a value of different data type than what is defined in the program. Do not include code to throw any exception in the program. Ex: If the input of the program is: 15 3 the output of the program is: 5 Ex: If the input of the program is: 10 0 the output of the program is: Arithmetic Exception: / by zero Ex: If the input of the program is: 15.5 5 the output of the program is: Input Mismatch Exception: java.util.InputMismatchException LabProgram.java…
In Java when a method throws a checked Exception, what must we always do when calling that method? A. Make sure to declare the method as static. B. Put it inside a try/catch block. C. Set the permission level of the method to private. D. Check our input, and if it will be bad input we must throw an exception before calling the method.
What is exception propagation? Give an example of a class that contains at least two methods, in which one method calls another. Ensure that the subordinate method will call a predefined Java method that can throw a checked exception. The subordinate method should not catch the exception. Explain how exception propagation will occur in your example.
