Hi I really need help with the methods for this lab for a computer science class. Thanks
Main (WordTester - the application)
-
is complete and only requires uncommenting to test the Word and Words classes as they are completed. The needed imports, class headings, method headings, and block comments are provided for the remaining classes. Javadocs are also provided for the Word and Words classes.
Word
-
The Word class represents a single word. It is immutable. You have been provided a skeleton for this class. Complete the Word class using the block comments, Javadocs, and the following instructions.
1. A String instance variable named word which will contain the word is declared and initialized in the constructor method for you.
2. The one parameter constructor to initialize the word instance variable is also completed.
3. Complete the getLength method to return the number of characters in the word.
4. Complete the getNumVowels method to return the number of vowels in the word. It should use the VOWELS class constant and String’s length, substring, and indexOf methods.
Do not use any String methods that are not in the AP Subset.
5. Complete the getReverse method to return a Word with the letters of this reversed.
6. Complete the toString method to return the String word.
7. Uncomment the Word test code in WordTester and make sure that Word works correctly.
Extra Credit
● Word – add the following methods to Word:
o public boolean equals(Object other) - This method will compare two Word
objects for equality.
o public Word getSortedUpperCaseWord() - This method will return a new Word with its letters changed to upper case and then sorted. You should create an array of Strings representing the uppercase of each of the letters. Then use either selection sort or insertion sort code to order the array. Then you will have to create a string from the array and then create the Word to return.
● Words – add the following method to Words:
o public void printAnagrams() - This method will print the pairs of anagrams in this. Two words w1 and w2 are anagrams if
w1.getSortedUpperCaseWord().equals(w2.getSortedUpperCaseWord()) is true. This method should only print each pair once.

Homework Answers
Hi Student,
I have completed few of the methods but few of the methods are to be written by you yourself. If you face any issue in that later, let me know, I will provide you the answers in comments.
Below is the code for the same and the output-
import java.util.Arrays;
public class Main

public static void main(String[] args)

// Test Word
Word one = new Word("chicken");
System.out.println("Word one: " + one);

System.out.println("Number of vowels: " + one.getNumVowels());
System.out.println("Reverse: " + one.getReverse());
System.out.println("\n\n");
// Test Words
Words test1 = new Words(new String[] {
"one", "two", "three", "four", "five", "six", "seven",
"alligator"});
System.out.println("Words test1: " + test1);
/* System.out.println("Number of words with 2 vowels: " +
