Question 01 - Exceptions Write a Java program that reads a list of integers from the user, and then calculates the average of the positive integers in the list. If there are no positive integers in the list, the program should throw a custom exception called "NoPositiveIntegersException". The program should be implemented as follows: I. II. III. IV. V. Create a custom exception class called "NoPositiveIntegersException" that printout the error message "There are no positive integers in the list" if there are no positive integers in the user entered list. Create another class called "AveragePositiveIntegers" to get the user inputs through the main method. The program should prompt the user to enter a list of integers, one integer per line. The user should indicate the end of the list by entering a negative integer (Ex: -2) Store the user entered positive integers in an ArrayList. Calculate the average of the positive integers and print it to the console, rounded to two decimal places. If there are no positive integers in the list, the program should throw a custom exception called "NoPositive IntegersException". Sample Output 1: Enter a list of integers, one integer per line. Enter a negative integer to end the list. -2 There are no positive integers in the list.

Java Exceptions: Your parents gave you an emergency cash card that has 2 restrictions:  it can't be used to purchase alcohol, and the purchase price must be less than $100.  Write a program segment in main() that will read 2 inputs from the user describing a purchase you are trying to make using the cash card:  the item purchased (eg runners) and the purchase price (eg 79.99).  Your code must check for the 2 restrictions mentioned above and generate exceptions if either one of them occurs (InvalidItemException or InvalidPurchasePriceException.  Assume that these have already been coded so you don't need to write them).  Your code must also deal with each exception by writing out an appropriate (specific) message stating what the problem is.  If there is no problem your code should generate a "Payment accepted" message.

A throw statement - throw new Exception() - is used to throw an exception.     True     False

The while loop reads values from input until an integer is read. Complete the exception handler in the while loop to catch an InputMismatchException exception and: Output "Removed unacceptable input for number of cents". End with a newline. Discard the invalid input. Ex: If the input is 20 60, then the output is: 20 cents = 4 nickels Processed one valid input value Ex: If the input is Aya Tia 20 60, then the output is: New JAVA code can only be added after code given:     Removed unacceptable input for number of cents Removed unacceptable input for number of cents 20 cents = 4 nickels Processed one valid input value Note: Each value read from input is on one line.       /*******************************************************************************************************                                New Java Code here: test input:   Aya Tia 20 60 *******************************************************************************************************/

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.

Develop an exception class named InvalidMonthException that extends the Exception class.   Instances of the class will be thrown based on the following conditions: The value for a month number is not between 1 and 12 The value for a month name is not January, February, March, … December Develop a class named Month.  The class should define an integer field named monthNumber that holds the number of a month.  For example, January would be 1, February would be 2, and so forth.  In addition, provide the following methods: A no-argument constructor that sets the monthNumberto 1. An overloaded constructor that accepts the number of the month as an argument.  The constructor should set the monthNumberfield to the parameter value if the parameter contains the value 1 – 12.  Otherwise, throw an InvalidMonthException exception back to the caller.  The exception should note that the month number was incorrect. An overloaded constructor that accepts a string containing the name of the month,…

A thrown exception may contain more information about what caused the exception. True or False

X1155: Throwing an Exception The method below takes in a String parameter representing a username. It should throw an Exception if the username is less than 3 characters long.
