- FOR JAVA Write a method that takes two integer arrays, and returns a new array by taking the intersection of the two arrays.in java wirte a method that given an integer array, computes and returns an integer x. the starting value of x is equal to the array length. for every odd element in the array, substract it from x, and for every even element in the array add it to x . Example: Array: [13,2,3,4,5] Result: x=5-13+2-3+4-5 x= -10You are given an array of n integers. Write a java method that splits the numbers of the array into two equal groups so that the GCD of all numbers in the first group is equal to one and the GCD of all numbers in the second group is not one. After splitting the numbers display the resulting groups as shown in the sample run below. Note: 1. The array has even size. 2. All elements of the array are less than 100. 3. You can define at most only one one-dimensional array. Sample run of the method: Input array: {6,7,9,4,3,2} Output Group one : {7,9,3} //Ignore Order of numbers. Order is not important Group two: {2,4,6} //Ignore Order of numbers. Order is not important
- FOR JAVA Write a method that takes a one dimensional integer array and an integer, and returns the index of the integer in the array. If the integer is not in the array, your program must return -1. If there are multiple occurrences of that number, your program must return the smallest index.Write a program in Java that reads integers, one per line, and displays their sum. Also, display all the numbers read, each with an annotation giving its percentage contribution to the sum. Use a method that takes the entire array as one argument and returns the sum of the numbers in the array. (Hint: Ask the user for the number of integers to be entered, create an array of that length, and then fill the array with the integers read.This is needed in java Given an array of doubles named heights, change the value at index 12 to 135.9.
- In Java: Ask the user to enter the size of an array. It must be greater than 0. Write a method, inputValidation, that returns the size of the array to the main.Needs to be written in java: Write a program with a main() method that asks the user to input an integer array of 10 elements.Next, create three methods described below. From inside your main() method, call each of thethree methods described below and print out the results of the methods 2, 3, which return values.1. printReverse() - a method that receives an array of integers, then reverses the elements ofthe array and prints out all the elements from inside the method. Print all in one lineseparated by commas (see sample output below).2. getLargest() – a method that receives an array of integers, then returns the largest integervalue in the array. (print result from main())3. computeTwice()- a method that receives the previously reversed array of integers, thenreturns an array of integers which doubles the value of each number in the array (see thesample output below). (print result from main())Sample output:Enter a number:22Enter a number:34Enter a number:21Enter a number:35Enter a…a Java method that will take in a double array as its sole parameter and return the difference between the highest and lowest values currently stored in the array. The header is: public static double getDiff ( double [ ] array )
- In JAVA Write the method below: Given a two-dimensional array containing integers, create a method called "matrixOperations" The method should do the following:1. Print out all the numbers in the array row by row (add empty line at the end of the row)2. For each row, print out the length of the row (each row is an array, remember)Needs to be written for Java and in one program: Write a program that asks the user to input two integers a and b. Pass the two input integers to method called “createArray”. Then create an array that has all integer from a to b. Return the array to main method and print the array from the main method Example 1: Input two numbers: 6 2 Array is [6, 5, 4, 3, 2] Example 2: Input two numbers: 4 8 Array is [4, 5, 6, 7, 8] 2. Pass the above array as a parameter to a method called average and return the average and print it out in the main method.Java programming language . Write a method to find the index of a value in an array of integer numbers and then test it. For example: int x = 20; int[] array = {12,5,46,20,98,75,49} => The output -> the index is = 3
