An array has faster access to its elements than a list does. Oc An ArrayList can grow or shrink as needed, while an array is always the same size O d. You can store objects in an ArrayList, but not in an array.

public class ArrayCommonOperations{ public static void main(String [] args) { //*** Task #1: Define and instantiate an array of integer numbers, with 10 elements //*** Task #2: Fill in the array with integer numbers from 1 to 100 //*** Task #3: define another array, named temp, and copy the initial array in it. //* This allows to preserve the original array //*** Task #4: Define the variables you need to calculate the following values, //* and initialize them with appropriate values. //*** Task #5: Print the original array //*** Task #6: Calculate the sum of all values //*** Task #7: Count the number of even values //*** Task #8: Calculate the minimum value in the array //*** Task #9: Calculate the maximum value in the array //*** Task #10: Replace the elements that are divisible by 3, with their value plus 2 //*** Task #11:...

X42: frontPiece Given an int array of any length, return a new array of its first 2 elements. If the array is smaller than length 2, use whatever elements are present. Examples: frontPiece ({1, 2, 3}) -> {1, 2} frontPiece ({1, 2}) -> {1, 2} Your Answer: Feedback Your feedback will appear here when you check 1 public int[] frontPiece(int[] nums) 2 { your answer. 3 4 }

JAVASCRIPT Write the function divideArray() in script.js that has a single numbers parameter containing an array of integers. The function should divide numbers into two arrays, evenNums for even numbers and oddNums for odd numbers. Then the function should sort the two arrays and output the array values to the console.

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...

Lab9C: 2D or not 2D For this exercise you will also be writing a program that will be building upon Lab9A. So please make new class file, copy, and rename the code you have already written for Lab9A. Please also rememb to rename the file and (and in the case of Java and C# students) class name to Lab9C. For this exercise, please take the array that was filled up with values and flatten it i.e., convert the 2-0 array to a 1-D array that contains the same values. Please do not just print the 2-D array to look li a 1-D array Hint: You will have to take the 2-D array's total amount of cells and make a 1-D array of the same siz Please refer to the sample output below for visualization and match its style. As always: Remember, the class name should be Lab9C. The user input is indicated in bold. Sample Output #1: Please enter the number of rows: 4 Please enter the number of columns: 4 I have 4 rows and 4 columns. I need to fill-up 16 spaces. The 4x4 array: 1|2|3|4| 5|6|7|8| 9|10|11|12|...

1. Array splitting in Java Create an integer array with 10 integer numbers, initialize the array arbitrarily but make sure there are both positive and negative integers. Then generate two arrays out of the original array, one array with all natural numbers (positive numbers or zeros) and another one with all negative numbers. Print out the number of elements and the detailed elements in each array.
