write a method called insert that inserts an element into an integer array. It should take 3 parameters: an int array, the number to be inserted and the index it should be inserted at. It should return a new array that has the element inserted at the index (the new array should have a length 1 longer than the original array).

3. write a method called insert that inserts an element into an integer array. It should take 3 parameters: an int array, the number to be inserted and the index it should be inserted at. It should return a new array that has the element inserted at the index (the new array should have a length 1 longer than the original array). Sample code int [] a = {1,2,3,4, 5}; int[] inserted = insert (a,9,0); printArray (inserted); int[] a = int[] inserted = insert(a,9,3); printArray (inserted); int[] a = {1,2,3,4,5}; int [] inserted = insert (a,9,5); printArray(inserted); Sample output 9123 4 5 {1,2,3,4,5}; 123945 1234 59

Write a program that creates a 2-D array initialized with test data . Use any primitive type of data EXCEPT int (Integer). The program should have all methods in the problem. getTotal - This method should accept a two-dimensional array as its argument and return the total of all the values in the array. getAverage - This method should accept a two-dimensional array as its argument and return the average of all the values in the array. getRowTotal. - This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. getColumnTotal - This method should accept a two-dimensional array as its First argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the total of the values in the specified column.…
TableAA.java Write a program that will store a multiplication table in a 2-D array. The user will enter how many lines (rows) it will have. The table will be printed to the screen. (Make it look nice – consider using printf.) This program will contain a static method. This method will take in an integer (the user’s number) and it will return a 2-D array. The code inside of the method will create the array, fill it with all the appropriate values that one would expect in a multiplication table, and then return that filled array. In the main method, you will ask the user how many lines they want to see and then you will use your static method to get the array. Once you have the array back from the static method, use nested for loops to print it in table form. See samples on the following pages. Program only needs to run once. Add try/catches so the user can only enter positive integers (1 and higher).
2. Rotate Left k cells Use Python Consider an array named source. Write a method/function named rotateLeft( source, k) that rotates all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] rotateLeft(source,3) After calling rotateLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]
Write a method with header static void DisplayIntArray(int[] numbers). The first argument is an array of ints. There is no return value. This method displays all the elements of the argument on a single line. Each item will occupy three columns.Call this method from main with a suitable argument. Write a method with header static int[] GenerateRandomIntArray(int numberOfItems, int largestValue). The first argument is an int indicating the number of elements that will be present in the return array. The second argument is an int representing the largest item in the array. The returned value is an array of integers. This method does the following: Declare and initialized a variable of type Random (Random generator = new Random();) Declare an array of type int (you may call it result) Allocate storage for the correct number of items Using your favorite looping statement, assign a random integer to each element of the array (result[i] = generator.Next(largestValue);) In your…
1. Write a program that calls a method that takes a character array as a parameter (you can initialize an array in the main method) and returns the number of vowels in the array. Partial program is given below. public class CountVowels{ public static void main(String[] args){ char[] arr= System.out.print("There are "+vowels(arr)+" vowels in the array");
A 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} to
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)**
Define 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…
Program71.java Write a program that creates a 32-element array of random integers all from 1 to 100, inclusive. Then execute a custom method with the array as its only argument. The method should begin by using a loop to print the array elements in 4 rows and 8 columns, with all columns being five characters wide. Duplicates are okay. This same loop should determine how many integers in the array are odd numbers. After this loop ends, use this figure to declare a new array of integers named odds. Process the array again in the method, but this time with a foreach loop, and add the odd integers to the odds array. Return the odds array back to main. In main, report the size of the array and sort it ascending. Finally use a while loop to print the odd integers all on one line separated by spaces. Program73.java In main: Declare an array capable of holding five first names. Populate the array in a for loop by entering five first names all on one line separated by spaces. sort the array…
