(PLEASE USE JAVA AND JFRAME GUI) Game rules:The game consists of a two-dimensional field of size m × n (game field). Each element ofthe game field is a button with a number assigned to it.Initialization of the game:• The numbers on the buttons of the game field are set to a random digit between 0and 9• The target value is displayed above the game field• The current sum of the numbers displayed on the buttons of the game field is printedbelow the game field• The number of moves to completion is displayed in the upper right corner above thegame field.Playing:The first move is determined by the player by selecting any button (button A) on thegame field.1. The player is allowed to choose a second button (button B) located in the columnor row of the previously selected button (A).2. Upon selecting the second button (B), the value of button (A) is updated accordingto the following formula: A = (AoperationB)mod10.3. The operation for the basic game will be +.4. Decrement the number of moves…

You will build a program to manage a race car in this assessment. The code will consist of a for-loop method that will run a car around a race track and cause “wear and tear” on the car. The car will perform x number of laps and will have to make pitstops when it either runs out of gas or needs a tire replacement. The for loop will be simple def wear_tires(car): tire -=1 def use_gas(car): gas -=1 c = Car() # You need to make this part for i in range(100): if the car needs a pitstop: perform pitstop else: wear_tires(c) use_gas(c) # Display the current cars wear in a much better format print(c.tire) print(c.gas) print(“Current Lap is: “ , i) For this task, you will have to use this for loop and build out the two methods in the main Python program. To use the above code, you must build two pieces of information. An abstract Vehicle class A Car class A RaceCar class Each with its methods and variables. This programming will involve using inheritance and abstraction to make a race car…

public setUpTrip(double, double): void Car's state is set to hold the speed of travel and distance to travel at that speed Precondition: none Postcondition: Car's state holds information on distance to travel and speed to travel Parameters: Average Speed to be driven, Distance to drive Develop and use an algorithm that calculates the amount of fuel used and the actual distance driven in the drive() method. The algorithm must use a formula that gives proportionately poorer mileage when the Car is driven faster or slower than its optimal speed. When a new Car object is instantiated, it is initialized with an optimal speed variable. Your fuel usage algorithm should set limits on how poor of MPG your car will get. You may add other methods and fields as needed. When a new Car object is created, the car’s odometer is set to a random number between 0.0 and 5.99, the car’s trip odometer is set to 0.0, its best fuel economy (MPG) is set to a random number between 15.0 and 54.99, its…
X609: Magic Date A magic date is one when written in the following format, the month times the date equals the year e.g. 6/10/60. Write code that figures out if a user entered date is a magic date. The dates must be between 1 - 31, inclusive and the months between 1 - 12, inclusive. Let the user know whether they entered a magic date. If the input parameters are not valid, return false. Examples: magicDate(6, 10, 60) -> true magicDate(50, 12, 600) –> false
Exercise 5 - Number to Word Make a new class in the Lab2 project called Num2wordthat prompts the user enter a number between 0 and 9 and then displays the corresponding word (i.e. "zero"for 0, "one"for 1, etc.). Use a switchstatement to do this. Include a default case that lets the user know they entered a wrong number. The switch statement has the following syntax: switch (variable) { case value1: // Code that should execute when variable==value1 break; // this prevents it from automatically going to the next case case value2: // Code that should execute when variable==value2 break; // this prevents it from automatically going to the next case default: // Code that should execute when variable has a value that didn't match the above }

Can you make a GUI in java that : 1. (game field) randomizes 9 numbers (form 0 to 9) numbers. randomizes n (rows) and collumns(m) ((from 1 to 4)) The result should be a GUI with a n x m matrix of buttons, each button should be a random number form 1 to 9. The idea is after every compile i should get a random arrangement 2. random target value is displayed above game field(100-300) 3. The current sum of the numbers displayed on the buttons of the game field is printedbelow the game field 4.The number of moves to completion is displayed in the upper right corner above thegame field. 5.current mathematical operation - add a component to the right side of the gamefield that displays the current mathematical operation. The current mathematicaloperation starts at +, after the first move it should randomize. The current mathematical operation only applies for one move, and after the move a new mathematicaloperation is randomly selected that will be evaluated in the next move. Choose fromthe…
