Question

creating a roulette wheel. The pockets are numbered from 0 to 36. The colors of the pockets are as follows: Pocket 0 is green. For pockets 1 through 10, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 11 through 18, the odd-numbered pockets are black and the even-numbered pockets are red. For pockets 19 through 28, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 29 through 36, the odd-numbered pockets are black and the even-numbered pockets are red. Create a class named RoulettePocket. The class's constructor should accept a pocket number. The class should have a method named getPocketColor that returns the pocket's color, as a string. Demonstrate the class in a program that asks the user to enter a pocket number, and displays whether the pocket is green, red, or black. The program should display an error message if the user enters a number that is outside the range of 0 through 36.

The goal of Snake is to create a snake as long as possible. This is achieved by guiding the snake to an apple on the game board. The snake cannot stop moving, and dies whenever it hits something (excluding apples). Because the snake is growing longer and longer as the game progresses, it gets increasingly difficult to avoid collisions with the snake itself. The player can change the direction of the head of the snake by using the arrow keys. At step in the game, there is always an apple somewhere on the board. If the snake eats an apple, the snake becomes one cell longer. A new apple is placed on a random location, excluding all places covered by the snake. When the snake reaches a side of the game board, it re-emerges at the opposite end.
