- 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 minA bit new to methods and need a little bit of help. Swap Method Your task is to write a public static method named swap that takes a single parameter which is an array of doubles. This method should swap the first and last element in the array and then return the adjusted double array. You can assume that all arrays passed into the method are a length of 2 or more. For example, the test data provided when passed into the swap method should go from: {8.34, 7.221, 10.643, 93.2} toUsing 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.

- To send an entire array to a method, pass the array name only as the argument: int[] numbers = new int[10]; for (int i=0; i < numbers.length; i++) { numbers[i] = i * 10; } printArray(numbers); //Sends the starting address of the array to the method so it can access all the values To send an individual element of an array to a method, you must include ________. the index number of the item: numbers[2] the first element the last element only the name of the arrayDefine an array to be a 121 array if all elements are either 1 or 2 and it begins with one or more 1s followed by a one or more 2s and then ends with the same number of 1s that it begins with. Write a method named is121Array that returns 1 if its array argument is a 121 array, otherwise, it returns 0. There is one additional requirement. You should return 0 as soon as it is known that the array is not a 121 array; continuing to analyze the array would be a waste of CPU cycles. If you are programming in Java or C#, the function signature isint is121Array(int[ ] a) If you are programming in C or C++, the function signature isint is121Array(int a[ ], int len) where len is the number of elements in the array a. Examples a is then function returns reason {1, 2, 1} 1 because the same number of 1s are at the beginning and end of the array and there is at least one 2 in between them. {1, 1, 2, 2, 2, 1, 1} 1 because the same number of 1s are at the beginning and end of…(Java) question 4 Complete the following method to insert a value into an array: public static void insert(String array[], int numElements, int indexToInsert, String newValue) { if (array.length == numElements) { System.out.println("Array is full. No room to insert."); return; } //start at end and work backwards shifting names down for (int i = numElements; i > indexToInsert; i--) { //fill in the missing line here } array[indexToInsert] = newValue;} Group of answer choices array[i - 1] = array[i]; array[i] = array[indexToInsert]; array[indexToInsert] = array[i]; array[i] = array[i - 1]; array[i] = array[i + 1];
- Write the following method that returns the locationof the smallest element in a two-dimensional array.public static int[] locateSmallest(double[][] a)The return value is a one-dimensional array that contains two elements. Thesetwo elements indicate the row and column indices of the smallest element in thetwo-dimensional array. Write a test program that prompts the user to enter a twodimensionalarray and displays the location of the smallest element in the array.Here is a sample run: Enter the number of rows and columns of the array: 3 4↵EnterEnter the array:23.5 35 2 10↵Enter4.5 3 45 3.5↵Enter35 44 5.5 9.6↵EnterThe location of the smallest element is at (0, 2)**Please Use Java as programming language. Create a class whose main() holds an array containing 10 integers. Create two methods that accepts the array. The first method named lowest returns the lowest from the 10 numbers while the second method named highest returns the highest number from the list. Determine the highest and lowest number without sorting the numbers. Your output should contain the original list of numbers, the highest and the lowest number from the list. Supply the necessary values for the array.The two-dimensional arrays m1 and m2 are strictlyidentical if their corresponding elements are equal. Write a method that returnstrue if m1 and m2 are strictly identical, using the following header:public static boolean equals(int[][] m1, int[][] m2)Write a test program that prompts the user to enter two 3 x3 arrays of integersand displays whether the two are strictly identical.
