- Make an array called array with three elements in it, a hashmap /dict / associative array called hash with three elements in it, and a string variable called str with at least 15 characters where one of those characters is duplicated twice (i.e., in the string at least 3 times). hint: declare -a array #creates an index array & declare -A hash #creates an associative array Use echo to print both your arrays (both ‘array’ and ‘hash’) as strings on a single line. (Use loops) Save just a portion of your indexed array to a new array variable. Write a loop to print out each item of the new array on a line by itself. Remove the last element from your indexed array. Remove the first element from your index array. Use echo to print out your indexed array on a single line. Use an if statement to do this: If your array contains 2, print “true” otherwise print “false” Create a read-only string variable and demonstrate that it cannot be changed. Echo a substring of str which…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 = 3An array index starts with -1 1 0. 2.
- getListRowIndices Method public static java.util.ArrayList<java.lang.Integer> getListRowIndices(int[][] array, int rowLength) This method returns an ArrayList with the indices of rows of the two-dimensional having a length that corresponds to rowLength. You may only use one auxiliary method. The method should create an ArrayList that is passed to the auxiliary in order to place the indices (if any). If no indices are found, an empty (size of 0) ArrayList will be returned. You can assume the array parameter will not be null and every row of the two-dimensional array has an array with a size of at least 0. Your implementation must be recursive and you may not use any loop construct. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: array - rowLength - Returns: ArrayList<Integer>Write a function that is passed an array of numbers and returns a hash table containing the minimum, maximum and average value. @{min=????; max-???; average=???} Test by passing the function 3 different arrays of randomly generated numbers. If the array is empty set all 3 values to zero. (3)JAVA PROGRAMMING Write a generic printArray shown in the sample below. Array contains: <value> <value>.... <valueN>
- given an array of integer values , return true if 6 appears as either the first or last element in the array. firstLast6([1,2,36]) true firstLast([6,1,2,3]) true firstLast([13,6,1,2,3]) falseJavanetbeans Use a one-dimensional array to solve the following problem: Write an application that inputs five numbers each of which is between 10 and 100, inclusive. As each number is read, display it only if it is not a duplicate of a number already read. Provide the “worst case”, in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values input after the user inputs each new value Initialize the integer array numbers to hold five elements. This is the maximum number of values the program must store if all values are input. 2. Validate the input and display an error message if the user inputs invalid data. 3. If the number entered is not unique, display a message to the user; otherwise, store the number in the array and display the list of unique numbers entered so far.Java Given a 2 dimensional array, write a method to return the average of each row. The result must be returned as a one dimensional array. The array may be ragged. For example: int[][] my2DArray = { {2,5,5}, {2,6,8,4}, {6,5,2,3} } The result should be: int[] myArrayAverage = { 4, //Average of {2,5,5} 5, //Average of {2,6,8,4} 4 //Average of {6,5,2,3} } Note: You only need to write down the code inside the myMethod() code block public class CST1201Test3 { public static void main(String[] args) { int[][] my2DArray = { {2,5,5}, {2,6,8,4}, {6,5,2,3} }; int[] myArrayAverage = myMethod(my2DArray)); } static int[] myMethod(int[][] numbers) { // your answer } }
- In Java write an application to Find minimum and maximum in array.Write a Java program to defind a method that calculates and returns the sum of integers stored in an array. Array content: (10, 20, 30, 40, 50)JAVA 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 9
