- In java Implement a public static double[] ageMetrics(Patient[] patients) method that returns an array of length 3 with the following three values (starting at index 0): The age of the youngest patient The age of the oldest patient The mean age of all patientsWrite a Java program that would resemble a payroll system. An input window which will accept the employee number and the number of days of rendered work. A 2d-arraylist that contains the employee number and the rate per day is to be searched and used to compute for the gross salary. Gross salary is computed by multiplying the number of days of rendered work by rate per day of the particular employee. If the gross salary computed is greater than 100,000 the tax is 20% of the gross salary, otherwise, the tax is 10%. Deduct the tax from the gross salary to get the net pay. Display the employee number, gross salary, tax deduction, and the net pay in an output window. Design your own input/output windows. ( USE OOP CONCEPT AND JOPTION)We were given the following code to solve a Pentomino puzzle, several methods might need to be added or editted to solve the problem. The program should take in an input of 3 4 5 6 for 3x20 4x15 5x12 6x10 grids.

- Implement the vacuum cleaning agent function in Python/Java for the scenario described below: Consider two-dimensional Boolean array of size m x n (m and n can each be equal to 4) where m is the number of rows, and n is the number of columns. Obtain numerical positive integer values for m and n as inputs from the user. Generate random numbers and scale them down to either a “0” or a “1” according to whether they represent “Clean” or “Dirty”, respectively. After filling the array with 0s or 1s, start at some random array position indicating the initial position of the vacuum cleaner. First check if at that current position, there is the presence of a “Dirt” or not determined by whether 0 or 1 is filled in at that initial position of the vacuum cleaner. If there is a “Dirt”, clean it, and if there is no “Dirt” do a No-operation. After this is done, generate random numbers modulo 4 to obtain random numbers 0, 1, 2, 3 indicating whether to take a left, right, up or down correspondingly. If…Write a Java program that would resemble a power utility billing system. There will be an input window that would enter or input the meter number (5 numeric digits) and the present meter reading in kilowatt-hours, the maximum would be 9999 kilowatts. A search from a 2d-ArrayList would be made in order to get the previous meter reading of a particular meter number. The 2d- ArrayList consists of meter number (5 numeric digits) and the previous meter reading in kilowatt-hours (4 numeric digits with 9999 as a maximum value). Provide at least 5 sample data or 5 rows with meter numbers and previous meter reading for each row for the 2d-ArrayList. When an input of meter number and present meter reading is made, search the 2d-ArrayList for the equivalent meter number. If a match is found, get the kilowatt-hour used (KWH) by subtracting the previous meter reading from the present meter reading. Note that if the present meter reading is less than the previous meter reading, add 10000 first to…a Java method that takes an array of primitive integers as its only parameter and returns the centered average of that list as a primitive double. The centere average is defined for this question as the average of all the values in the array except for the largest and smallest values. If smallest or largest value occurs more than once, disregard only one copy of each as appropriate. the length of the array is at least 3 and every location in the array has been assigned a value
- Write a Java program that expands a given binomial (x + y)^n, where integer n is user input. To do the work of the binomial expression, first create a method that accepts n as a parameter and then returns an array holding the coefficients needed for the binomial expansion using the Pascal’s Triangle method. Create a 2nd method which takes the array holding the coefficients as a parameter and prints the appropriate binomial expansion. For example, if n = 5 is entered by the user, the method calculating the coefficients should return {1,5,10,10,5,1} and the method that prints the expansion should print the following: (x + y)^5 = x^5 + 5x^4y + 10x^3y^2 + 10x^2y^3 + 5xy^4 + y^5 Your main method should use an appropriate loop for repeated inputs and automatically call the methods to calculate the coefficients and print the binomial expansion. There isn’t a need for a menu although you should ask the user if they want to quit or continue after their binomial expansion is printed each time.…Write a JAVA program that handles a 2-dimensional array representing a 3x3 tic-tac-toe board. In the game, players take turns writing an X or an O and trying to get three in a row. Write three methods, one to solve for a horizontal win, one to solve for a vertical win, and one to solve for a diagonal win. A win occurs when three symbols for a player are in a line (horizontal, vertical, or diagonal). Create four 2-d (3x3) arrays, one with a horizontal win for O, one with a vertical win for X, one with a diagonal win for O, and the last being a cat game (no player wins). It is tempting to populate the arrays with a ‘X’ and ‘O’ characters but consider representing these values with int values instead which makes calculating a win much easier. Consider a zero value as an empty cell. You do not have to write code to input the values, just define the four arrays using initializer lists (see example below). For example: an array with { {1, 0, -1}, {1, -1, 0}, {1, -1, 0} } has a vertical…In java, Write a method checks if a given matrix is a unit matrix. An N x N unit matrix is a matrix of N rows and N columns where all the diagonal elements are ‘1’s and all the remaining elements are ‘0’s. The method should take a 2D array of integers as argument and return a Boolean which is true/false depending on whether the matrix corresponding to the 2D array is a unit matrix or not. Test the method in the ‘main’ method. For problems asking for 'methods', you need to write the method, and the 'main' method which is used as a 'driver' to test the given method.
- Write a library of static methods that performs various geometric transforms on polygons. Mathematically, a polygon is defined by its sequence of vertices (x0, y 0), (x 1, y 1), (x 2, y 2), …. In Java, we will represent a polygon by storing the x– and y-coordinates of the vertices in two parallel arrays x[] and y[]. Three useful geometric transforms are scale, translate and rotate. Scale the coordinates of each vertex (x i, y i) by a factor α. x‘i = α xi y‘i = α yi Translate each vertex (x i, y i) by a given offset (dx, dy). x‘i = xi + dx y‘i = yi + dy Rotate each vertex (x i, y i) by θ degrees counterclockwise, around the origin. x‘i = xi cos θ – yi sin θ y‘i = yi cos θ + xi sin θ Write a two-dimensional transformation library by implementing the following API: public class PolygonTransform { // Returns a new array object that is an exact copy of the given array. // The given array is not mutated. public static double[] copy(double[] array) // Scales the polygon by the factor…FOR JAVA Write a Java method that takes two 2 dimensional int arrays (a and b) and a 2 dimensional boolean array (c) where all three arrays have the same size. Your method should return an array (result) such that, if a partic- ular element in c is true, then the corresponding (same indexed) element in result must be the multiplication of the the corresponding elements of a and b. If the element in c is false, then the the corresponding element in result must be the negative of multiplication of the the corresponding element in a and b. For example ifa = {{1,2,3},{4,5}},b = {{1,2,1},{0,2}} andc = {{true,false,true},{false,true}}, then the result should be result={{1, -4, 3}{0, 10}}.Write a program in java in which we had an array and you have to find Whether this array is monotonic or not
