2. write two method called findIndex and findLastlndex that search for a number in anarray. they should take an int array and an int as parameters. findIndex should return theindex of the first instance of the number in the array. findLastIndex should return theindex of the last instance of the number in the array. They both should return -1 if thenumber is not found. Do not use any library methods.Sample codeSample outputint al] = {10,50,30,40,50};1%3Dint x = findlndex(a,50);System.out.println(x);int al] = {10,50,30,40,50};4%3Dint x = findLastIndex(a,50);System.out.println(x);int al] = {10,50,30,40,50};-1%3Dint x = findIndex(a,70);System.out.println(x); Homework 11. Use method overriding to write two methods called printArray. On should take an intarray and the other should take a double array. Both should print the array they are givenas an argument.Sample codeSample outputint] x = {9, 3, 5, 1, 5, 10};9 3515 10int] y = {26.12, 72.1, 10, 4.20};26.12 72.1 10.0 4.2%3D

Note:- solved first question. Please repost second question . Logic:- use loop from 0 to lastIndex…

/*In this program you need to implement four methods with the following signatures:printArr(int[] a)add(int[] a, int[] b)subtract(int[] a, int[] b)negate(int[] a) 1. Method printArr(a) should print out all elements of a given int array in one line. 2. Method add(a, b) should take two int arrays (assume they have the same length) and return a new array each element of which will be the sum of the corresponding elements in a and b 3. Method subtract(a, b) is similar to add(), except it returns (a - b) array 4. Method negate(a)takes an int array and returns a new array in which every element is multiplied by -1. */ public class ArrayOperations{ public static void main(String[] args){ //The main only has the testing code. //You don't have to change it. int [] a = { 1, 2, 3, 4, 5}; int [] b = {10, 1, 3, 5, 7}; System.out.print("a = "); printArr(a);//Should print each element of a (in one line) System.out.print("b = ");…
Write a class ArrayClass, where the main method asks the user to enter the four numbers. Create a method printArray that prints the array whenever required (use Array.toString method). Make the program run as shown in the Sample Run below. Use Array.sort, Arrach.bianrySearch, Array.equals Sample RunList1, Enter four numbers: 2 3 3 2List2, Enter four numbers: 6 2 5 4List3, Enter four numbers: 5 2 4 6Your original List1: [2, 3, 3, 2]Your original List2: [6, 2, 5, 4]Your original List3: [5, 2, 4, 6]Sorted List1 is: [2, 2, 3, 3]Enter a number from the sorted List1 to search for: 3Value 3 is in index 2 (or position 3)List that are the same when sorted: [2, 4, 5, 6
The Utilities class contains three independent static methods and contains no fields (none should be added).The Utilities class contains the following 3 static methods that you must implement:1. QWERTY – If the argument is null, the length is anything other than 6, or if the element values are outside the inclusive boundof 1 to 7 throw the IllegalArgumentException with the message "Invalid parameter". Otherwise return a char array that hasinput[0] instances of 'Q', followed by input[1] instance of 'W', ....followed by input[5] instances of 'Y'. The length ofthe returned array should be the exact size needed to accommodate all the letters (no smaller or larger).2. turnTo1D – You can assume that the parameter array has at least 1 row and all rows are int array (might be an empty int array)and the parameter delta is a positive integer. The method returns a 1D array (possibly empty array) with all the values inarray that are in the range of the inclusive bound [value – delta to value +…
Write a method that returns a new array by eliminating theduplicate values in the array using the following method header:public static int[] eliminateDuplicates(int[] list)Write a test program that reads in 10 integers, invokes the method, and displaysthe distinct numbers separated by exactly one space. Here is a sample run of theprogram: Enter 10 numbers: 1 2 3 2 1 6 3 4 5 2 ↵EnterThe distinct numbers are: 1 2 3 6 4 5
Write a program that declares an array of 15 integers and reads the values from the user. Make sure that the user doesn’t enter a value greater than 10 (if the user enters a value not in the allowed range, discard that value and read another to put into the array). Now tell the number that occur maximum number of times in the array. For example for the following 7 has maximum occurrence. 4,7,3,3,2,7,1,5,7,9,9,9,7,8,10 Use both linear and binary search.
Please use java. Write array methods that carry out the following tasks for an array of integers by creating and completing the “WorkingWithArrays” class below. Add documentation comments for each method. Provide a test program called ‘Lab5_yourID.java” that tests methods of WorkingWithArrays class. In your test program, use random class to generate array values.public class WorkingWithArrays{private int[ ] values; //declare instant variables//constructorpublic WorkingWithArrays (int[ ] initialValues) {values = initialValues;}public void MoveOddElements( ) { … }public boolean containDuplicate( ) {…}}• Method MoveOddElements: moves all odd elements values to the front (if any exist), otherwise preserve the order of the elements.• Method containDuplicate: returns true if the array contains duplicate elements (not necessary to be adjacent)
1)Write a method that takes an array of ints and returns the sum of all numbers that are even. For example, given an array {3, 4, 6}, you would return 10. 2)For this exercise, you are given an array of integers. Return true if every element in the array is an odd number, otherwise return false. 3) Given an array of strings, return the array in reverse order. For example, given: reverse({"one", "two", "three"}); You would return: {"three", "two", "one"} 4) 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"}
An element in the array is a peak (max or min) if the elements before and after that element are greater than the element itself (min) or the elements before and after that element are less than the element (max). Write a method in your program called displayPeaks that will take a single-dimensional array as parameter and display all peak elements of that array (line by line) together with their index and whether they are max or min. For example, calling the method displayPeaks from main method will display: 83 at position 0 is a max 48 at position 1 is a min 89 at position 2 is a max 40 at position 4 is a min 94 at position 5 is a max 12 at position 8 is a min 87 at position 11 is a max 10 at position 12 is a min 78 at position 14 is a max 2 at position 15 is a min 52 at position 18 is a max 46 at position 19 is a min
Write a java application which initializes an array with ten random integers between 1 and 6. Write two methods: 1. arraySwap: this method should accept an integer array and swap the first and the last item. 2. findMinimum: this method should accept the array and return the minimum value of that array You should comment and follow javaDoc for both methods. Your main method should test each of these methods.
java In this task, you need to write 2 overloaded methods findMax() that will find a maximum number in the array. First version should work with array of integers (int[]) and return int, and second method should work with an array of doubles (double[]) and return double as a result. Methods must have the same name and different parameters.
Using Java Eclipse IDE (Average an array) Write two overloaded methods that return the average of an array with the following headers: public static int average(int [] array) public static double average(double [] array) Write a test program that prompts the user to enter 10 double values, invokes this method, then displays the average value.
Write a method that finds the largest element in an array of double values using the following header: public static double max(double[] array) Write a test program that prompts the user to enter ten numbers, invokes this method to return the maximum value, and displays the maximum value.
