Write a method markLength4 that takes an ArrayList of Strings as a parameter and that places a String of four asterisks ("****") in front of every String of length 4. For example, suppose that an ArrayList called "list" contains the following values: (this, is, lots, of, fun, for, every, Java, programmer) And you make the following call: markLength4(list); Then list should store the following values after the call: (****, this, is, ****, lots, of, fun, for, every, ****, Java, programmer) Notice that you leave the original Strings in the list (this, lots, Java) but include the four-asterisk String in front of each to mark it. You may assume that the ArrayList contains only String values, but it might be empty.
Write a Program in Java programming: Support you have an ArrayList containing random integers. These integers can be any number, and each integer can appear more than once. For example, [2, 19, 21, 19, 21, 1, 3, 3, 6, 21, .....] Your job is to write a method called findEvenFrequentNumbers(ArrayList<Integer> list) that returns an ArrayList which has all the numbers appears in even frequency and in increasing order. e.g. list = [2, 19, 21, 19, 21, 1, 3, 3, 6, 21], should return [3, 19] list = [3, 3, 3, 1, 2, 2, 2, 2, 2], should return [] list = [1, 1, 1, 1, 1], should return [1] Note that you need to provide a class with the main function and also the imports.
Write a static method called "flip4" that takes an ArrayList of integer values as a parameter and that rewrites successive sequences of four values in the list. For each sequence of four values, the method will swap the first element and the fourth element and then swap the second element with the third element. For example, suppose that a variable called list stores the following sequence of values: [3, 8, 19, 42, 7, 26, 19, -8, 193, 204, 6, -4] and we make the following call: flip4(list); Afterwards the list should store the following sequence of values: [42, 19, 8, 3, -8, 19, 26, 7, -4, 6, 204, 193] Each sequence of three elements will be rotated so that the 3rd value becomes the 1st value and the other two are moved to the next higher index; ie. the 1st becomes the 2nd and the 2nd becomes the 3rd. If the list has extra values that are not part of a sequence of three, those values are unchanged. For example, if the list had instead stored: [3, 8, 19, 42, 7, 26, 19,…
Write a method quicksort that takes in an ArrayList of integers and returns them in ascending order, using a quicksort style of sorting. Remember that this style relies on choosing a pivot integer and breaking the set into values less than the pivot and more than the pivot, then repeating this process on each half until only single values are left, which are then put back together. public ArrayList<Integer> quickSort(ArrayList<Integer> list) { *code here*}
Write a method manyStrings that takes an ArrayList of Strings and an integer n as parameters and that replaces every String in the original list with n of that String. For example, suppose that an ArrayList called "list" contains the following values: ("squid", "octopus") And you make the following call: manyStrings(list, 2); Then list should store the following values after the call: ("squid", "squid", "octopus", "octopus") As another example, suppose that list contains the following: ("a", "a", "b", "c") and you make the following call: manyStrings(list, 3); Then list should store the following values after the call: ("a", "a", "a", "a", "a", "a", "b", "b", "b", "c", "c", "c") You may assume that the ArrayList you are passed contains only Strings and that the integer n is greater than 0.

Write the method filterBySize().* * Given an ArrayList of String, return a new list where only * strings of the given length are retained.* * Examples:* filterBySize(["a", "bb", "b", "ccc"], 1) returns ["a", "b"]* filterBySize(["a", "bb", "b", "ccc"], 3) returns ["ccc"]* filterBySize(["a", "bb", "b", "ccc"], 4) returns []
Given an arraylist of positive integers, write a java method to return the number of rotations to the right inorder to obtain the largest sequence of odd integers. Hint: the largest sequence of odd integers may be obtained after 0<= numRotations <= n-1. where n is the number of elements in the arraylist. Note: Rotating to the right means moving all elements one position to the right, i.e. element at position 0 will move to position 1 and element at position 1 will move to position 2 ... element at position n-1 will move to position 0.
Write a method that removes the duplicate elements froman array list of integers using the following header:public static void removeDuplicate(ArrayList<Integer> list)Write a test program that prompts the user to enter 10 integers to a list and displaysthe distinct integers in their input order and separated by exactly one space.Here is a sample run: Enter 10 integers: 34 5 3 5 6 4 33 2 2 4 ↵EnterThe distinct integers are 34 5 3 6 4 33 2
FOR JAVA Write a method that takes a one dimensional integer array, an integer (as index) and another integer (as number). Your program must insert the number into the given index, shift the rest of the elements to the right, and return the new array. For instance, if we want to insert the number 0 into position 3 of {1, 2, 3, 4, 5}, your method must return {1, 2, 3, 0, 4, 5}.
Implement unique method that takes an ArrayList as input and returns an ArrayList withexactly a single occurrence of each element from the input list. For example, if the input listcontains 5, 6, 7, 6, 3, 5, 5, 4 then the output list should have 5, 6, 7, 3, 4.Note: (1) You may assume that the ArrayList has a specific type of elements in it. In the class, we assumedit to have String type values. (2) You may only work with ArrayList(s).
