JAVA LANGUAGE Create an ArrayList, Name it YourRegNoandName that can hold Integers, and fill each slot with a different random value from 1-50. Display those values on the screen, and then prompt the user for an integer to search through the ArrayList, and if the item is present, say “FOUND”. It is not necessary to display anything if the value was not found. If the item is in the ArrayList multiple times, it's okay if the program prints the message more than once.

Display those values on the screen, and then prompt the user for an integer to search through the ArrayList, and if the item is present, say so. It is not necessary to display anything if the value was not found. If the item is in the ArrayList multiple times, it's okay if the program prints the message more than onceJava question Use the Iterator Pattern: Create a class called Exercise, and then, in its main method, create an ArrayList called stringArrayList. Add the following five strings to stringArrayList: “one”, “two”, ”three”, ”four”, ”five”. Then, use a for loop and the index of stringArrayList to print all these five strings out to the console. 2. For stringArrayList above, can you use an iterator to traverse the five strings inside, without using the index? 3. If change stringArrayList into a TreeSet, how do you traverse the five strings use an iterator? Implement an Iterator: 4. Create a class called StringArray that is able to store a number of String objects. Create an instance variable, String[] values, (internal data storage) of StringArray to store all the strings. 5. Create a constructor for StringArray, which is able to build an object of StringArray using the parameter. public StringArray(String[] values) 6. Make the class StringArray implements…Write a Java Console application in which you initialize an arraylist with 10 String values. For example, 10 colour names, or fruit names, or veg names, or car names, etc. Display all the values in the list in a neat tabular format. Randomly select a value from the array. Now allow the user 3 chances to guess the value. After the first incorrect guess provide the user with a clue: the first letter of the randomly selected word. After the second incorrect guess provide the user with another clue: the number of letters in the word. Once the user correctly guesses the word, remove that word from the list. Display the number of items in the list. The user must have the option to play again.
- In this lab assignment you need to implement the method named middleValue, in a program named ArrayOps.java. The method accepts an array of integer values as a parameter, and returns the value in the middle of the array. For instance, if an array contains five elements, then the third element would be the middle element to be returned. However, if the array contains six elements, both the third and fourth values could be considered to be the middle elements. In this case, only return the first middle value, namely, the third element of the array. Complete the method middleValue, and test the correctness of your method in main(). Particularly, you should create two arrays (arbitrary values), one array with odd length, and the other with even length, and print out the middle values of these two arrays.You will be given an ArrayList of Integers. This ArrayList will have at least 2 items. Starting with the second string in the list, remove it if the string before it comes first alphabetically. Then print the ArrayList. You cannot change the method header! public ArrayList<String> removeStrings(ArrayList<String> arrList) { return null; // Return the ArrayList as well as printing it. }For this code in java, I'm stuck on an error im getting on line 21 and need help delcaring the name in an array named PlayerName.

- Write a program that do the following: Ask the user to input his/her first name and store it in a String variable. Create an ArrayList with the type String. Each letter of the inputted name should be stored in a separate element of the ArrayList. Print the ArrayLists. Note: Your answer should have the code as text, as well as a screenshot of the code with the output. The inputted name should be your first name. Name : RababgetListRowIndices 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>Array lists are objects that, like arrays, provide you the ability to store items sequentially and recall items by index. Working with array lists involves invoking ArrayList methods, so we will need to develop some basic skills. Let’s start with the code below: import java.util.ArrayList;public class ArrayListRunner{ public static void main(String[] args) { ArrayList<String> names = new ArrayList<String>(); System.out.println(names); }} The main method imports java.util.ArrayList and creates an ArrayList that can hold strings. It also prints out the ArrayList and, when it does, we see that the list is empty: [ ].Complete the following tasks by adding code to this skeleton program. If you are asked to print a value, provide a suitable label to identify it when it is printed.a) Invoke add() to enter the following names in sequence: Alice, Bob, Connie, David, Edward, Fran, Gomez, Harry. Print the ArrayList again.b) Use get() to retrieve and print the first…
