Check this code for this assignment: It runs successfully on Netbeans IDE but there is no output.// Create a Scanner object to read user input Scanner input = new Scanner(System.in); // Prompt the user to enter the street number System.out.print("Enter street number: "); int streetNumber = input.nextInt(); input.nextLine(); // Prompt the user to enter the street name System.out.print("Enter street name: "); String streetName = input.nextLine(); // Prompt the user to enter the number of rooms in the house System.out.print("Enter number of rooms: "); int numRooms = input.nextInt(); input.nextLine(); // Create an array to store the room types String[] roomTypes = { "living", "dining", "bedroom1", "bedroom2", "kitchen", "bathroom" }; // Create an array to store the area of each room int[] roomAreas = new int[6]; // Prompt the user to enter the area of each room…

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…
