- java Write a program to do the following: Create an ArrayList of Student. Add 7 elements to the ArrayList. Use for each loop to print all the elements of an ArrayList. Remove an element from an ArrayList using the index number. Remove the element from an ArrayList using the content (element name).Compare and contrast the array and arrayList. Give at least one example that describe when to use arrayList compared to an array.Given an ArrayList of integers, return an ArrayList where all the odds are before the evens in the order that they occur. public ArrayList<Integer> solution(ArrayList<Integer> nums) {ArrayList<Integer> finalList = new ArrayList<>();int index = 0;for (int i = 0; i < nums.size(); i++) {if (nums.get(i) % 2 == 1) {finalList.add(index, nums.get(i));index++;} elsefinalList.add(nums.get(i));}return finalList;} This is my failing code. for [1.-3.3] where [1,3,-3] is being returned
- Write a Java program to create a new array list, add the following data {PHP, Java, C++, Python} and print out the collection.a) Print out all elements using foreach.b) Insert an element (JavaScript) into the array list at the first position.c) Remove the third element from the array list.d) Search an element (C++) in the array list.e) Remove all elements from the ArrayList.Using Java create an array, Arraylist, and a vector.Create an arraylist in Java of 10 students. Use the following methods: add, remove, insert, size, capacity, contains ,and clear
- Write a program in java that randomly fills in 0s and 1s into an n-by-n matrix, prints the matrix, and finds the rows and columns with the most 1s. (Hint: Use two ArrayLists to store the row and column indices with the most 1s.)If N represents the number of elements in the collection, then the contains method of the ArrayCollection class is O(1). True or False If N represents the number of elements in the list, then the index-based add method of the ABList class is O(N). True or FalseUsing JAVA, write a method that modifies an ArrayList<String>, moving all strings starting with an uppercase letter to the front, without otherwise changing the order of the elements. Write a test program to demonstrate the correct operation of the method.
- in java language import java.util.ArrayList;import java.util.Arrays; Write the method named mesh.* * Start with two ArrayLists of String, A and B, each with * its elements in alphabetical order and without any duplicates. * Return a new list containing the first N elements from the two * lists. The result list should be in alphabetical order and without * duplicates. A and B will both have a size which is N or more. * Your solution should make a single pass over A and B, taking * advantage of the fact that they are in alphabetical order, * copying elements directly to the new list.* * Remember, to see if one String is "greater than" or "less than" * another, you need to use the compareTo() method, not the < or > * operators. * * Examples:* mesh(["a","c","z"], ["b","f","z"], 3) returns ["a","b","c"]* mesh(["a","c","z"], ["c","f","z"], 3) returns ["a","c","f"]* mesh(["f","g","z"], ["c","f","g"], 3) returns ["c","f","g"]* * @param a an ArrayList of String in alphabetical order.*…What is the time complexity associated with accessing a single value in an array?
