Main difference between an array and an ArrayList is that an ArrayList can store more data types an ArrayList can store more elements an ArrayList executes faster for retrieval and insertion an ArrayList takes care of the memory management automatically an ArrayList uses positions and an array uses indices

query the user for the size of an array of integers build an array of integers and fill it with random integer values. The values will range between 0 and 100 display the array clone the array display the cloned array sort the cloned array display the original array and the sorted cloned array create another array that is double the size of the cloned array and copy the data from the cloned array into the new array. Then fill the remaining cells in the new array with random values. These will also range between 0 and 100.Note: int[] newArray = new int[clone.lenght*2] Write program in jva

Return the First Element in an Array JavaScript Create a function that takes an array containing only numbers and return the first element. Examples getFirstValue ([1, 2, 3]) → 1 getFirstValue ([80, 5, 100])→ 80 getFirstValue ([-500, 0, 50])-500

A single dimensional array might be treated as a 2-dimensional array.

#Steps: Create a Main class. Declare an ArrayList in the main() method and store the given values in it. Create an array called output of the size of the ArrayList. Iterate through for-loop to get each element from the array List and load it into the array using the get() method of the list. Print the array to see the loaded elements.     import java.util.ArrayList; import java.util.List; public class Main {     public static void main(String[] args) {                 List<String> nameList = new ArrayList<String>();        nameList.add("Robert");        nameList.add("Samson");        nameList.add("Alex");        nameList.add("William");                    System.out.println("Elements of List: " + nameList);                 // Create an array of the same size as nameList Hint: use size() method                   // Fetch the elements from the nameList and insert into newly created array                  // Hint: Use get() method to fetch the elements from…

Example in Java Create an array, access, update and process its elements
