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.

Rules: Corner cases. Throw the specified exception for the following corner cases: Throw an IllegalArgumentException if the client calls either addFirst() or addLast() with a null argument. Throw a java.util.NoSuchElementException if the client calls either removeFirst() or removeLast when the deque is empty. Throw a java.util.NoSuchElementException if the client calls the next() method in the iterator when there are no more items to return. Unit testing. Your main() method must call directly every public constructor and method to help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. Your implementation must achieve the following worst-case performance requirements: A deque containing n items must use at most 48n + 192 bytes of memory, not including the memory for the items themselves. Each deque operation (including construction) must take constant time. Each iterator operation (including construction) must take…
Java Exception method withdraw throws an exception if amount is greater than balance. For example: Test Result Account account = new Account("Acct-001","Juan dela Cruz", 5000.0); account.withdraw(5500.0); System.out.println("Balance: "+account.getBalance()); Insufficient: Insufficient funds. Balance: 5000.0 Account account = new Account("Acct-001","Juan dela Cruz", 5000.0); account.withdraw(500.0); System.out.println("Balance: "+account.getBalance()); Balance: 4500.0
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.
Create a flowchart and modify the code. INSTRUCTION: Create a new class called CalculatorWithMod. This class should be a sub class of the base class Calculator. This class should also have an additional method for calculating the modulo. The modulo method should only be seen at the sub class, and not the base class! Include exception handling for instances when dividing by 0 or calculating the modulo with 0. You would need to use throw, try, and catch. The modulo (or "modulus" or "mod") is the remainder after dividing one number by another.Example: 20 mod 3 equals 2Because 20/3 = 6 with a remainder of 2 CODE TO COPY: #include <iostream> using namespace std; class Calculator{public:Calculator(){printf("Welcome to my Calculator\n"); } int addition(int a, int b);int subtraction(int a, int b);int multiplication(int a, int b);float division(int a, int b);}; int Calculator::addition(int a, int b){return (a+b);} int Calculator::subtraction(int a, int b){return (a-b);} int…
99 question Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tells the ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not. If the ticket number is valid, save the number to a .txt file called “tickets.txt” and.
Question (1): Write a program that asks the user to enter an integer greater than zero and store it in a variable called “n". Then it calculates the final value that will be stored in a variable called “s" according to the following equation. 1х 2 2 x 3 3 x 4 4 x 5 Nx (N+ 1) .. ( + or - ) 2 3 4 5 N+1 And add an exception when the user enters any value other than integer shows the message “You entered non integer value, please try again.", and let the user to enter a new value. Enter an integer: 4 Example 1 S = -2.0 Enter an integer: a You entered non integer value, please try again. Ехample 2 Enter an integer: 4 S = -2.0
