Question

1. Use the wordList to provide data for the following program. Create three arrayLists named smallWords, medWords, and largeWords. Parse through the array, and place the words that are 4 letters or less in to the smallWords ArrayList. Words between 5 and 9 letters are placed into the medWords list. Words larger than 9 letters are placed into the largeWords list. Once the words are separated, print the size() of each arrayList

2. Create a class called Drywall that holds the length, width, and height for a room. Include a method in class Drywall that calculates the number of sheets needed to drywall this room. A 4x8 drywall sheet covers 32 sq feet. Round up the sheets to a whole number with no decimals . Create an array of 4 different rooms. Total up the total number of drywall sheets needed for the 4 rooms

Hi, I have answered Q1.

Please repost other in separate post.

Please let me know in case of any issue.

import java.util.ArrayList;

public class ArrayListTest {

   public static void main(String[] args) {

       // we have given wordList

       ArrayList<String> wordList = new ArrayList<>();

       // adding some words

       wordList.add("Ok");

       wordList.add("Pravesh");

       wordList.add("Apple");

       wordList.add("Ball");

       wordList.add("Cat");

       wordList.add("A");

       wordList.add("Lowest");

       wordList.add("Average");

       wordList.add("Grabage");

       wordList.add("Umberalla");

       wordList.add("September Month");

       wordList.add("yes");

       wordList.add("Love");

       wordList.add("I love you");

       // creating three ArrayList

       ArrayList<String> smallWords = new ArrayList<>();

       ArrayList<String> medWords = new ArrayList<>();

       ArrayList<String> largeWords = new ArrayList<>();

       for(String word : wordList){

           if(word.length() <= 4)

               smallWords.add(word);

           else if(word.length() <= 9)

               medWords.add(word);

           else

               largeWords.add(word);

       }

       System.out.println("Size of samll words: "+smallWords.size());

       System.out.println("Size of medium words: "+medWords.size());

       System.out.println("Size of large words: "+largeWords.size());

   }

}

/*

Sample run:

Size of samll words: 6

Size of medium words: 6

Size of large words: 2

*/
