A Memory Matching Game in java code with a 4x4 grid of Squares that when you click on a square it shows a number. It would have to be 2 of each number 1-8 and if the two squares that are clicked match then the squares stay on the grid. If they do not match after picking 2 squares they flip back over

Using quicksort to sort an array of car objects by various criteria. Define a class Car as follows: class Car { public String make; public String model; public int mpg; // Miles per gallon } a) Implement a comparator called CompareCarsByMakeThenModel that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByMakeThenModel should return a value that will cause quicksort to sort an array of cars in ascending order (from smallest to largest) by make and, when two cars have the same make, in ascending order by model. b) Implement a comparator called CompareCarsByDescendingMPG that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByDescendingMPG should return a value that will cause quicksort to sort an array of cars in descending order (from largest to smallest) by mpg. c)…
In geometry, polygons are defined as plane (two-dimensional) and closed shapes that are formedby three or more straight lines joined with each other. Write a java program to develop an OOPsolution presenting a regular polygon object. A regular polygon has a name, n number of sideswith the same length. The perimeter of a regular polygon can be found by computing the totallength of all n sides. A polygon can be a triangle that also has a height value.Create the following classes and interface:A. Interface Geometry includes a single method called perimeter() that returns a doublevalue presenting the perimeter of a shape.B. Implement class Polygon as follows: Include the required instance variables as described above, and a constructor method witharguments. Add two get methods to return number of sides and value of side length. Implement the method perimeter() from the Geometry interface as the perimetervalue of a polygon. Implement area() method that returns value 0.0; Override…

4.2.3: Method definition: Volume of a pyramid. Define a method pyramidVolume with double parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. Relevant geometry equations: Volume = base area x height x 1/3Base area = base length x base width.(Watch out for integer division). import java.util.Scanner; public class CalcPyramidVolume { //answer goes here// public static void main (String [] args) { Scanner scnr = new Scanner(System.in); double userLength; double userWidth; double userHeight; userLength = scnr.nextDouble(); userWidth = scnr.nextDouble(); userHeight = scnr.nextDouble(); System.out.println("Volume: " + pyramidVolume(userLength, userWidth, userHeight)); }}
IN VISUAL BASIC, solve Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.
A popular word game involves finding words from a grid of randomly generatedletters. Words must be at least three letters long and formed from adjoining letters.Letters may not be reused and it is valid to move across diagonals. As an example,consider the following 4 * 4 grid of letters: A B C DE F G HI J K LM N O P The word “FAB” is valid (letters in the upper left corner) and the word “KNIFE”is valid. The word “BABE” is not valid because the “B” may not be reused. Theword “MINE” is not valid because the “E” is not adjacent to the “N”. Write a program that uses a 4 * 4 two-dimensional array to represent the gameboard. The program should randomly select letters for the board. You may wishto select vowels with a higher probability than consonants. You may also wish toalways place a “U” next to a “Q” or to treat “QU” as a single letter. The programshould read the words from the text file words.txt (included on the website withthis book) and then use a recursive algorithm to…
Scylla or Charybdis? def scylla_or_charybdis(moves, n): This problem was inspired by the article "A Magical Answer to the 80-Year-Old Puzzle" in Quanta Magazine. Thanks to your recent cunning stunts, your nemesis in life is trapped inside a devious game where, for a refreshing change from the usual way of things, you get to be the Final Boss. (Everyone is the hero in their own story until they become a villain in somebody else's, after all.) This final level is a one-dimensional video game platform that reaches n-1 steps from its center to both directions. At each end of this platform exactly n steps away from the center, your two lethal friends Scylla and Charybdis are licking their lips in anticipation of a tasty morsel. Your nemesis starts at the center of this platform. To start this deadly combat of wits, she must immediately commit to her entire sequence of future moves, given to this function as a string of characters '+' (“� just a step to the ri-i-i-i-ight � ”) and '-' (move…
