#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…
17. Suppose that you had the following main program, what would the Customez Arraylist look like? - draw an abstract picture. 3 import java.util.Arraylist; 4 5 public class TestProgram { 6 78 public static void main(String[] args) { string names [] - ("Jessica", "Manuel", "Karen", "Robert", "Sasha"}; 18 11 ArrayList customers - new ArrayList(); 12 13 14 15 16 17 for (int i = 0; i< names.length; i++) { customers.add(new Customer(names [1], (int) (Math.random() * 10) + 1)); } 18 19 1 20

java program : Assume the following method is added to the ArrayStack class. What does this method do? public ArrayStack<E> Undefined() { int j = topOfStack; ArrayStack<E> st1= new ArrayStack<E>(topOfStack + 1); for(int i = 0; i < topOfStack + 1; i++) { st1.theData[j] = theData[i]; j-- ; } return st1; } The method will return a stack containing all the elements of “this” stack in the reverse order. The method will return a stack containing the alternative elements of “this” stack in the original order. The method will return a stack containing all the elements of “this” stack in the original order. The method will return a stack containing the alternative elements of “this” stack in the reverse order.
