Serendipity Booksellers has a book club that awards points to its customers based on the number of books purchased each month. The points are awarded as follows:
• If a customer purchases 0 books, he or she earns 0 points.
• If a customer purchases 1 book, he or she earns 5 points.
• If a customer purchases 2 books, he or she earns 15 points.
• If a customer purchases 3 books, he or she earns 30 points.
• If a customer purchases 4 or more books, he or she earns 60 points.
Write a program that asks the user to enter the number of books that he or she has purchased this month and then displays the number of points awarded.
Write an application that reads an integer and determines and prints whether it’s odd or even. [Hint: Use the remainder operator. An even number is a multiple of 2. Any multiple of 2 leaves a remainder of 0 when divided by 2.]

- Problem specification: There is a grid of NXN squares. We can easily determines how many different rectangles (squares are excluded) there are in the grid. For example, in a 3X3 grid, you can find 22 different rectangles, marked as the green rectangles. You can see that we did not count the red ones as they are squares. In this assignment, you will write a Java program that takes the value of N as input and determines the total area of all the rectangles in the grid. Assume that the smallest squares in the grid have length 1. So a 3X2 rectangle will have an area of 6. For example, the total area of all the rectangles in the 3X3 grid is 66.…arrow_forwardPart 2 - OddOrEven ClassIn bluej. Write a program that prompts the user to enter an integer.

- 2. Write an application that plays the game of Fermi. Generate three distinctrandom digits between 0 and 9. These digits are assigned to positions 1, 2,and 3. The goal of the game is for the player to guess the digits in threepositions correctly in the least number of tries. For each guess, the playerprovides three digits for positions 1, 2, and 3. The program replies with ahint consisting of Fermi, Pico, or Nano. If the digit guessed for a givenposition is correct, then the reply is Fermi. If the digit guessed for a givenposition is in a different position, the reply is Pico. If the digit guessed for agiven position does not match any of the three digits, then the reply is Nano.Here are sample replies for the three secret digits 6, 5, and 8 at positions 1,2, and 3, respectively:Guess Hint Explanation1 2 5 Nano Nano Pico The value 5 matches butat the wrong position.8 5 3 Pico Fermi Nano The value 5 matches atthe correct position.

When played between two people, each personpicks one of three options (usually shown by a hand gesture) atthe same time, and a winner is determined. In the game, Rockbeats Scissors, Scissors beats Paper, and Paper beats Rock. The program should randomly choose one of the three options (with-out revealing it), then prompt for the user's selection. At that point, the program reveals both choices and prints a statementindicating if the user won, the computer won, or if it was a tie.Continue playing until the user chooses to stop, then print thenumber of user wins, losses, and ties.arrow_forwardAnalyze the following code: int x = 0;int y = ((x < 100) && (x > 0)) ? 1: -1; The code has syntax error. y becomes 1 after the code is executed. y becomes -1 after the code is executed.
