To change the clock from a 24-hour clock to a 12-hour clock Program Plan: Â Â Modify a program in BlueJ using Java and achieve the 12-hour clock. The clock should display the midnight and afternoon time as 12:30 and not as 00:30. The minute should be displaying values from 0 to 59 and the hour should be displaying values from 1 to 12.

Question

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.

PLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS. Write a class RangeInput that allows users to enter a value within a range of values that is provided in the constructor. An example would be a temperature control switch in a car that allows inputs between 60 and 80 degrees Fahrenheit. The input control has “up” and “down” buttons. Provide up and down methods to change the current value. The initial value is the midpoint between the limits. As with the preceding exercises, use Math.min and Math.max to limit the value. Write a sample program that simulates clicks on controls for the passenger and driver seats.

Rearrange the code below to provide two additional CashRegister methods: an enterPayment method that reduces the total price by the given payment, and a giveChange method that returns the change due and resets the total price and item count. Not all lines are useful.
