Swaped the first and last elements in array.
Replace all even elements with 0.
Shift all elements by one to the right and move the last element into the first position. For example, 1 4 9 16 25 would be turned i into 25 1 4 9 16.
Replace each element except first and last the larger of its two neighbors.

- For this exercise, you need to shift all the elements in the array one space to the right (increase the index of the element by 1). The last element will wrap around and become the new first element. For example, given: moveUp({"first", "second", "third", "fourth"}); You would return: {"fourth", "first", "second", "third"} in javaJAVA complete a method that swaps the first and second half of an array of integers. For example, if the array contains the values 1 4 9 16 25 36then after calling the method, it should contain the values16 25 36 1 4 9If the array contains an odd number of elements, leave the middle element in place. For example, 1 4 9 16 25 36 45becomes25 36 45 16 1 4 9Write a Java program to implement the following by using class Arrays: Read 5 student marks and keep them in array marks Print the elements of array marks Copy the content of array marks to another array copyMarks Sort the array marks in ascending order and print the sorted array Compare whether the two arrays marks and copyMarks are equal Search for the mark 88.0 in the array markse and print appropriate message Hint: use toString() for print, arraycopy() for copy, sort() for sort, equals() for comparison, and binarySearch() for search
- Write in java code Create an array myArr of 10 integer elements and initialize/fill it with numbers (not sorted) between 0 and 20; for example myArr = [ 12, 3, 19, 5, 7, 11,….etc.]. (a) print the array. (b) Use method sort() of class Arrays to sort myArr and print it after sorting. (c) Use the arraycopy() method of class System to copy myArr to another array called my2ndArr, then print both arrays. (d) use method equals() of class Arrays between the two arrays and print the results. (e) use method fill() to fill my2ndArr with 99 in all elements and then use method equals()and print the result whether the two arrays are equal or not. (f) use the method binarySearch() to search myArr for the value 15 and print the resultin java Declare and initialize an array with 8 integer elements. Use therandom method of the Math class to initialize the values with randomintegers between 1 and 50 (exclude 50) and print each of them onConsole.in java Create two arrays with same length n: - Array A with integer numbers that user will insert- Array B with random numbers from 0 to 100.- Find sum of both arrays,- Find maximum values of both array and compare them: .if maximum of 1 st is lower then maximum of 2nd array: print sums of both arrays.if maximum of 1st is greater then maximum of 2nd array print 2nd array (use println)otherwise print first array in reverse.
- JAVA PROGRAMMING Two words (spelt in uppercase) are similar if and only if all letters in the 1st word are in the 2nd word and all letters in the 2nd word are in the 1st word; including the same number of duplications. For example, ABBA and BABA are similar; however, BABA and BAAA are not similar. To check two words which are similar, we can use two integer arrays, each has 26 elements (as we have 26 letters), you can assume that 1st array element stores the number of letter ‘A’, 2nd array element stores the number of letter ‘B’, and so on. What you need to do now is to check whether the two integer arrays are equal to decide whether the two words are similar. We propose following UML for this question: The class TwoWords has two String instance variables. In this class, other than the constructors, accessor and mutator methods; we have two important methods: the countInfo method receives a String parameter (a word, for example) counts and stores the letters’ info in an integer…Write a Java 7 program with proper whole code and Explatation too,,. & Dont use JAVA8... Shil got an array of N integers as a present on his birthday. But he didn't liked it. Shil wants to make this array beautiful. Shil considers an array A1,A2,A3 . . . AN beautiful if A1 > AN. Inorder to make it beautiful Shil can swap any two numbers in the array. Also Shil can perform this operation any number of times on any adjacent pairs of integers in the array A.Find the number of ways in which Shil can make this array beautiful.Two ways are considered same if resulting array after making all the swaps have same A1 and AN. Input First line of input contains an integer N denoting the number of elements in an array A. Next line of input contains N space separated integers denoting A1,A2,A3 . . . AN respectively. Output Number of ways in which you can make given array beautiful. Constraints 1 ≤ N ≤ 1061 ≤ Ai ≤ 106 SAMPLE INPUT 5 1 4 3 2 5 SAMPLE OUTPUT 10 Explanation…The rotateLeft method takes an array of integers, and an integer number of places, and returns a new copy of the array that contains a "rotated" version of the input array. Rotation means that elements have been shifted leftwards by that number of places, moving elements off one end of the array and onto the other end. For example, [11, 12, 13, 14, 15] rotated left by 2 places results in [13, 14, 15, 11, 12].
- JAVA: Below is a method intended to modify the input array by doubling each element and a main method that calls it. What does this code print out? If the method does not do what is intended, what needs to be modified?A prime integer is any integer that is evenly divisible only byitself and 1. The Sieve of Eratosthenes is a method of finding prime numbers. It operates as follows:a) Create an array with all elements initialized to 1 (true). Array elements with prime subscriptswill remain 1. All other array elements will eventually be set to zero. You’ll ignoreelements 0 and 1 in this exercise.b) Starting with array subscript 2, every time an array element is found whose value is 1,loop through the remainder of the array and set to zero every element whose subscriptis a multiple of the subscript for the element with value 1. For array subscript 2, all elementsbeyond 2 in the array that are multiples of 2 will be set to zero (subscripts 4, 6,8, 10, etc.); for array subscript 3, all elements beyond 3 in the array that are multiplesof 3 will be set to zero (subscripts 6, 9, 12, 15, etc.); and so on.When this process is complete, the array elements that are still set to one indicate that the subscriptis a…Write java program to create one dimensional array (MyList) of size 10, initialize its first two elements by reading them from the keyboard. Use for loop to fill its other eight elements such that each element is the sum of the previous two elements (i.e. the third element is the sum of first element and second element, and so on). b) Write two methods, the first one to calculate and print the sum of even numbers in the above (MyList) array. The second is to calculate and print the count of odd elements in (MyList) array. c) Answer the following questions: a. Print all elements of the array (MyList) such that each line has only three elements (two elements with its sum). b. Create a java program that enable you to check if an integer number is divisible by 7 and 9, and also if it’s divisible by 7 or 9 but not both.
