Write a Java method that takes an array of float values and determines if all the numbers are different from each other (that is, they are distinct).

Write a Java method that takes a two-dimensional ragged array as input and uses that array to print the following output: Two dimensional Ragged Array: ABCD EF G H I Then write a Java program to test your method.

Write a Java program to make two arrays containing random integer values (You can make these arrays with specific sizes using the below makeRandomArray method). The program should sum these two arrays and prints the resulted array (the array that contains the result of the two arrays summing). The program should also show the maximum element of the resulted array. Your program must define and call the following methods to perform the program as illustrated above: 1- A method int [] makeRandomArray(int size ,int a , int b) that makes and returns an array with specific size. The methods fills this array with random integers in a range [a..b] 2- A method public static int findmax(int x[ ]) that finds the maximum value of a number of x array passed to the method. 3- A method public static void printArray(int x[ ]) that prints the elements of the array x passed to the method. 4- A method public int[ ] sumTwoArrays(int x[ ], int y[ ]) that sums the elements of the two arrays(x and y...

Write the Java method averageOfDoubles that is passed an array of double values, and returns the average of the array values.You can assume the array length is a positive integer.

Write a Java program to take an array of ints, print the number of 9's in that array.

Write a java method called switchThem that accepts two integer arrays as parameters and switches the contents of the arrays. Take into account that the arrays may be of different sizes.

Write a complete java program that will store the weekly sales data for a small shop that sells candles into two dimensional array of type double, the shop has five candle scents as follow: week 1 sales week 2 sales week 3 sales week 4 sales Candle Scent 1 41.41 23.33 4.09 1.20 Candle Scent 2 33.86 22.30 27.85 17.35 Candle Scent 3 8.58 7.97 0.61 28.39 Candle Scent 4 10.23 32.62 22.21 21.91 Candle Scent 5 43.16 12.57 20.33 2.40 Your program should calculate and prints the followings: Total sa for week 1 Total sales for week 2 Total sales for week 3 Total sales for week 4 Maximum sales with the week number and candle scent number was found. Minimum sales with the week number and candle scent number was found. Sample run: Total Sales of Week 1 = 137.25 Total Sales of Week 2 = 98.80 Total Sales of Week 3 = 75.09 Total Sales of Week 4 = 71.26 Maximum Sales = 43.16 found week 1 for candle scent 5 Minimum Sales = 0.61 found in week 3 for candle scent 3

The programming language used is Java

java a. A method named contains exists that takes an array of Strings and a single String, in that order, as arguments and returns a boolean value that is true if the array contains the given String. Assume that an array of Strings named names is already declared and initialized. Call the method to see if the array contains the name "Fred", and save the result in a new variable named fredIsHere. b. Given a method named printMessage that takes a String argument and returns nothing, call the method to print out "I love Java!".

I need help with creating a Java program described below: Minesweeper.Write a program that reads three numbers, m, n, and p and produces an m-by-n Booleanarray where each element is occupied with probability p. In the minesweeper game, occupiedcells represent bombs and empty cells represent safe cells.Print out the array using an asterisk for bombs and a period for safe cells.Then, create an integer two-dimensional array with the number of neighboring bombs (above,below, left, right, or diagonal). * * . . . * * 1 0 0. . . . . 3 3 2 0 0 . * . . . 1 * 1 0 0Write your code so that you have as few special cases as possible to deal with, by using an(m+2)-by-(n+2) Boolean array.

Write a Java program (BasicStatistics.java) that prompts the user to enter 10 numbers as double values, computes the mean and standard deviation of those numbers, and prints the result. To earn full credit for this problem, you must use an array and separate methods for computing mean and standard deviation. Here is a sample run of a correct program (user input indicated by orange text):Enter 10 numbers: 1.9 2.5 3.7 2 1 6 3 4 5 2The mean is 3.11The standard deviation is 1.55738

Write a Java program that reads an integer N from the user and declares an integer array of size N. It then inputs N non-negative integers from the user into the array and do the following: 1. Finds and prints the minimum, maximum, sum, and average of the numbers. 2. Displays array data as a histogram – graphically by plotting each numeric value as a bar of asterisks (+) as shown in the example diagram. This is somehow similar to Lab11 Sample output Enter the size of array: 9 Enter 9 integer values: 10 19 5 14 Minimum = Maximum = 19 = 68 = 7.55 Sum Average ========== Histogram: ======= Element Ua lue 10 19 Histogran T T T Arial v T = ABC 3 (12pt) II Com

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....
