How exactly can one determine how successful an ArrayList really is?

public class PokerAnalysis implements PokerAnalyzer {   privateList<Card>cards; privateint[]rankCounts; privateint[]suitCounts;   /** * The constructor has been partially implemented for you. cards is the * ArrayList where you'll be adding all the cards you're given. In addition, * there are two arrays. You don't necessarily need to use them, but using them * will be extremely helpful. *  * The rankCounts array is of the same length as the number of Ranks. At * position i of the array, keep a count of the number of cards whose * rank.ordinal() equals i. Repeat the same with Suits for suitCounts. For * example, if your Cards are (Clubs 4, Clubs 10, Spades 2), your suitCounts * array would be {2, 0, 0, 1}. *  * @param cards *            the list of cards to be added */ publicPokerAnalysis(List<Card>cards){ this.cards=newArrayList<Card>(); this.rankCounts=newint[Rank.values().length]; this.suitCounts=newint[Suit.values().length];…

How can the performance of an ArrayList be evaluated?

How can you examine the current status of an ArrayList to determine how well it is working?

java Create a static method that: is called repeatAll returns ArrayList of Booleans takes in a single parameter - an ArrayList of Booleans This method should modify its ArrayList parameter by repeating its ArrayList values. For example, if the parameter is   (true, false, false) The modified ArrayList should be   (true, false, false, true, false, false)    public static void main(String[] args) {    Scanner in = new Scanner(System.in);    int size = in.nextInt();    ArrayList<Boolean> list = new ArrayList<>();    for(int i=0; i < size; i++) {      list.add(in.nextBoolean());    }     System.out.println(repeatAll(list));   }  }

4. Now examine the ArrayList methods in the above table, a) Which method retrieves elements from the ArrayList? b) Which method replaces the value of an element that already exists in the ArrayList? c) Which two methods initializes the value of an element? d) How do the two methods in (c) differ? Which method(s) would be appropriate in the above Java program (after we convert it to work with ArrayLists)?

Please give a detailed answer and code examples for all of the questions below.What is an array and linked list?What the difference between array and List?Difference between ArrayList and Arrays in Java?

java Create a method that: is called timesTwo returns an ArrayList of Integers takes in a single parameter - an ArrayList of Integers called nums This method should take the ArrayList parameter and multiply every value by two.   public static void main(String[] args) {    Scanner in = new Scanner(System.in);    int size = in.nextInt();    ArrayList<Integer> list = new ArrayList<>();    for(int i=0; i < size; i++) {      list.add(in.nextInt());    }     System.out.println(timesTwo(list));   }  }

Java ArrayLists can only be filled with reference type data, so you cannot fill them with primitive type data. How can you work around this with integers? (How can you have an ArrayList filled with integers?)

public class arrayOutput ( public static void main (String [] args) { final int NUM ELEMENTS = 3; int[] userVals = new int [NUM_ELEMENTS]; int i; } Type the program's output userVals [0] = 2; userVals [1] = 6; userVals [2] = 8; for (i = userVals.length - 1; i >= 0; −−1) { System.out.println(userVals [1]); } C.C. ? ? ??
