Given a user defined exception called InvalidAgeException, change the method ageCheck to throw this an InvalidAgeException if the person's age is less than 18. Then change the main method so that it catches the InvalidAgeException thrown by ageCheck and prints the "Age should be 18+" if it is thrown. class InvalidAgeException extends Exception { public InvalidAgeException (String s) // Call constructor of parent Exceptiọn super (s); public class Person { public void ageCheck(int age) { System.out.println("Acceptable age."); public static void main (String args[]) { Person obj obj.ageCheck (12); new Person (};

Suppose the exception class TestException is defined as follows:public class TestException extends Exception{public TestException(){super("Test Exception thrown!");System.out.println("Test exception thrown!!");}public TestException(String message){super(message);System.out.println("Test exception thrown with an argument!");}public void testMethod(){System.out.println("Message is " + getMessage());}}What output would be produced by the following code (which is just anexercise and not likely to occur in a program)?TestException exceptionObject = new TestException();System.out.println(exceptionObject.getMessage());exceptionObject.testMethod();The class TestException is on the website that comes with this text.
Suppose the exception class CrazyException is defined as follows: public class CrazyException extends Exception { public CrazyException() { super("Crazy exception thrown!"); System.out.println("Wow, Crazy exception thrown!"); } public CrazyException(String message) { super(message); System.out.println("Wow, crazy exception thrown with "+ "an argument!"); } public void crazyMethod() { System.out.println("Message is " + getMessage()); } } What output would be produced by the following unlikely code?

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.
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)
Please do this in Java! 3. RetailItem Exceptions Programming Challenge 4 of Chapter 6 required you to write a RetailItem class that holds data pertaining to a retail item. Write an exception class that can be instantiated and thrown when a negative number is given for the price. Write another exception class that can be instantiated and thrown when a negative number is given for the units on hand. Demonstrate the exception classes in a program. /** *Description: This program will displays a string without any user interaction *Class: Fall - COSC 1437.81002 *Assignment1: Hello World *Date: 08/15/2011 *@author Zoltan Szabo *@version 0.0.0 */ For each method, you will also be required to create docstring as follows: /** * @param String as args * @return Termination code as int, 0 for normal, anything else is error condition * @throws Nothing is implemented */ Flowcharts/UML and Pseudo code All assignment questions must show design flowchart/UML and/or pseudo code unless otherwise…
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…
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. **This is the output i am having trouble with. on line 20 The print string shows the print(ve, 'could not calculate heart rate info.') And i know that the extra space i see at the begining of that second line of output is due to the comma but I cannot figure out how to make the same line print but with out the space from the comma after…

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.
A pedometer treats walking 2,000 steps as walking 1 mile. Write a stepsToMiles() method that takes the number of steps as an integer parameter and returns the miles walked as a double. The stepsToMiles() method throws an Exception object with the message "Exception: Negative step count entered." when the number of steps is negative. Complete the main() method that reads the number of steps from a user, calls the stepsToMiles() method, and outputs the returned value from the stepsToMiles() method. Use a try-catch block to catch any Exception object thrown by the stepsToMiles() method and output the exception message. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("%.2f", yourValue);
