Car Instrument Simulator
For this assignment, you will design a set of classes that work together to simulate a car’s fuel gauge and odometer. The classes you will design are the following:
- The Fuel Gauge Class: This class will simulate a fuel gauge. Its responsibilities are as follows:
- To know the car’s current amount of fuel, in gallons.
- To report the car’s current amount of fuel, in gallons.
- To be able to increment the amount of fuel by 1 gallon. This simulates putting fuel in the car. (The car can hold a maximum of 15 gallons.)
- To be able to decrement the amount of fuel by 1 gallon, if the amount of fuel is greater than 0 gallons. This simulates burning fuel as the car runs.
- The Odometer Class: This class will simulate the car’s odometer. Its responsibilities are as follows:
- To know the car’s current mileage.
- To report the car’s current mileage.
- To be able to increment the current mileage by 1 mile. The maximum mileage the odometer can store is 999,999 miles. When this amount is exceeded, the odometer resets the current mileage to 0.
- To be able to work with a FuelGauge object. It should decrease the FuelGauge object’s current amount of fuel by 1 gallon for every 24 miles traveled. (The car’s fuel economy is 24 miles per gallon.)
Demonstrate the classes by creating instances of each. Simulate filling the car up with fuel, and then run a loop that increments the odometer until the car runs out of fuel. During each loop iteration, print the car’s current mileage and amount of fuel.

(Date Class) Create a class called Date that includes three pieces of information as datamembers—a month (type int), a day (type int) and a year (type int). Your class should have a constructor with three parameters that uses the parameters to initialize the three data members. For thepurpose of this exercise, assume that the values provided for the year and day are correct, but ensurethat the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a set and a get function for each data member. Provide a member function displayDate that displays the month, dayand year separated by forward slashes (/). Write a test program that demonstrates class Date’s capabilities.
Dice Rolling Class
In this problem, you will need to create a program that simulates rolling dice. To start this project, you will first need to define the properties and behaviors of a single die that can be reused multiple times in your future code. This will be done by creating a Dice class.
Create a Dice class that contains the following members:
Two private integer variables to store the minimum and maximum roll possible.
Two constructors that initialize the data members that store the min/max possible values of rolls.
a constructor with default min/max values.
a constructor that takes 2 input arguments corresponding to the min and max roll values
Create a roll() function that returns a random number that is uniformly distributed between the minimum and maximum possible roll values.
Create a small test program that asks the user to give a minValue and maxValue for a die, construct a single object of the Dice class with the constructor that initializes the min and max…
In the board game Scrabble, each tile contains a letter, which is used to spell words in rows and columns, and a score, which is used to determine the value of words. The point of this exercise is to practice the mechanical part of creating a new class definition:
Write a definition for a class named Tile that represents Scrabble tiles. The instance variables should be a character named "letter" and an integer named "value".
Write a constructor that takes parameters named letter and value, and initializes the instance variables.
Create getters for both of the attributes. (No setters, so that a Tile is immutable.)
Implement the .toString() and .equals methods for a Tile.
Your completed Tile class should work with this Main program (Links to an external site.) so that it produces sample output like shown at the end of the program. You can Fork the program to make your own version in Replit, where you can add your Tile.java, or you can copy the program to your own Java development…

This means that a customer who rents equipment for 41 or more minutes past an hour pays more than a customer who waits until the next hour to return the equipment.
