Make a copy of an ArrayList with an explicit loop. Complete the following code. ArrayListCopy.java 1 import java.util.ArrayList; 2 import java.util.Scanner; 3 4 public class ArrayListCopy 5 { public static void main(String[] args) { ArrayList words = new ArrayList(); Scanner in = new Scanner(System.in); while (in.hasNext()) words.add(in.next()); 7 8 10 11 12 13 ArrayList copy0fWords = new ArrayList(); // Use a for loop to copy the contents of words for (int i = 0; i < copy0fWords.size(); i++) { words = 14 15 16 17 copy0fWords.get (i); 18 19 20 } words.remove(0); // Shouldn't affect the copy System.out.println(words); System.out.println(copy0fWords); } 21 22 23 }

Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print:7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1. Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades[4]). Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. #include <iostream>using namespace std; int main() {   const int NUM_VALS = 4;   int courseGrades[NUM_VALS];   int i;    for (i = 0; i < NUM_VALS; ++i) {      cin >> courseGrades[i];   }    /* Your solution goes…

How can I evaluate an ArrayList's efficiency?

How can | iterate over the ArrayList made up of integers using the while loops in the java programming language?

Define a collection “ArrayList” to store the students' names. Use a loop to take 5 students’ names from the user and store them in the collection. Add two student names to the collection and remove the last name in the list. Insert a student name in third place in the collection. Sort the names alphabetically. Ask the user to enter a student name and search for it in the collection and prints the result as “Found” or “Not Found”. Print the whole collection using the enhanced for loop.   (java)

public static void reverse(ArrayList<Integer> alist){}public static ArrayList<Integer> reverseList(ArrayList<Integer> alist){}   How to use these two headers method and a main method to create the output of  [1,2,3] [3,2,1]

To declare an array of String called myStrings, we would code: ArrayList<Blank 1> myStrings = Blank 2 ArrayList<String>();

Javascript Use a for/of loop to iterate over the array of students. For each student, use a template literal to print out their name, age, and major in a formatted string. (e.g. John is 18 years old and is studying Computer Science.) Within the template literal, use object dot notation to access the name, age, and major properties of the student object. Use a console.log() to print out the formatted string for each student. Test the code by running it and verifying that it prints out the details of each student in a formatted string.============================================================================== const students = [   { name: "John", age: 18, major: "Computer Science" },   { name: "Newton", age: 19, major: "Mathematics" },   { name: "Barry", age: 20, major: "Physics" }, ]; // Iterate through the array of objects students using for/of     // Print a message to the console that includes the student's name, age, and major     // Example: John is 18 years old and…
