#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 nameList = new ArrayList();        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 arraylist and use for loop                  //                 System.out.print("Elements of Array: ");         for (int i = 0 ; i < output.length ; i++){             System.out.print(output[i] + "  ");         }     } }

1) What is one main disadvantage of an ArrayList? 2) Write a Java statement to create an ArrayList called list to hold 25 integers. 3) What is the type of the ArrayList defined in question number 2? 4) Write a for loop to initialize the objects in the ArrayList created in question number 2 above to -1.

Create in Java (1) Create an array of String objects and populate it with the days of the week (7 days)(i.e., Monday - Sunday)(2) Create an array parallel to the one created in (1) to store the entrées. However, you do not have this information, soyou will need to write a loop that prompts the user to enter the entrée served on that day. This prompt shouldinclude the day for which you are asking for the information (e.g., "What entrée is being served on Monday?")(3) Create another parallel array that stores the prices. You will also need to collect this information from the user. Thistime, your prompt should include the name of the entrée for which you are asking for the price(4) Prompt the user to choose an entrée from a list that you display numbered 1 through 7 (have them input a number1 to 7) and search the array and output the day on which the entrée will be served(5) Search through the array for the highest price entrée and output the name of this entrée for the user including…

Java code  8. Given an existing ArrayList named friendList, find the first index of a friend named Sasha and store it in a new variable named index. 9. Given that an ArrayList of Integers named numberList has already been created and several values have already been inserted, write the statement necessary to insert the value 25 at the end of the list. 10. Declare an integer array named evens and fill it with even numbers from 2 through 10 in one statement. 11. Given an existing array named pets, find the size of the array and store it in a new variable named numPets. 12. Given an existing ArrayList named contactList, find the number of contacts in the ArrayList and store it in the existing variable named numContacts.

mergeAndRemove(int[], int[]) This is a public static function that takes a int[] and int[] for the parameters and returns an int[]. Given two arrays of integers. Your job is to combine them into a single array and remove any duplicates, finally return the merged array.

For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20,30, 1 #include 2 3 int main(void) { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; 4 6 7 8 scanf("%d", &keysList[0]); scanf ("%d", &keysList[1]); scanf("%d", &keysList[2]); scanf("%d", &keysList[3]); 10 11 12 13 scanf ("%d", &itemsList[0]); scanf ("%d", &itemsList[1]); scanf("%d", &itemsList[2]); scanf ("%d", &itemsList[3]); 14 15 16 17 18 19 /* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24 }

vWhat happens when an object such as an array is no longer referenced by a variable?

Method Details getCountInRange public static int getCountInRange​(int[] array, int lower, int upper) Returns the number of values in the range defined by lower (inclusive) and upper (inclusive) Parameters: array - integer array lower - lower limit upper - upper limit Returns: Number of values found  Throws: java.lang.IllegalArgumentException - if array is null or lower is greater than upper Any error message is fine (e.g., "Invalid parameters(s)")
