Question

What java program would you write to solve the following problems and why does it work? Please also comment on other students’ code at least three times. 1) Implement MyArrayList and MyLinkedList using MyList interface and MyAbstractList as defined in Java Collection Framework. 2) For the following problem use your own created MyArrayList or MyLinkedList if needed. Given an array of words and a width maxWidth, format the text such that each line has exactly maxWidth characters and is fully (left and right) justified. You should pack your words in a greedy approach; that is, pack as many words as you can in each line. Pad extra spaces ' ' when necessary so that each line has exactly maxWidth characters. Extra spaces between words should be distributed as evenly as possible. If the number of spaces on a line do not divide evenly between words, the empty slots on the left will be assigned more spaces than the slots on the right. For the last line of text, it should be left justified and no extra space is inserted between words.

import java.io.*;

import java.util.*;

class GFG {

    public static void main(String[] args)

    {

        // Size of the LinkedList

        int n = 5;

        List<Integer> ll = new LinkedList<Integer>();

        for (int i = 1; i <= n; i++)

            ll.add(i);

        System.out.println(ll);

        ll.remove(3);

        System.out.println(ll);

        for (int i = 0; i < ll.size(); i++)

            System.out.print(ll.get(i) + " ");

    }
