Hi I am almost done with this lab with for my class but I keep getting an error message when I try and call the getReverse method on the getPalindrome method. Any help would really be appreciated.
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.
/**
* Word.java
* A Word object represents a word.
*/
public class Word
{
/** The 5 vowels to use for the getNumVowels() method */
private static final String VOWELS = "AEIOUaeiou";
/** The word instance variable */
private String word;
/**
* Constructs a Word object. No change needed.
* @param w the string used to initialize the word.
*/
public Word(String w)
{
word = w;
}
public String getReverse()
{
String reverse = "";
for (int i = word.length() - 1; i >= 0; i--)
{
reverse += word.substring(i, i + 1);
}
return reverse;
}
/**
* Determines if word is palindrome. Same word forward and backward
* @return true if word is palindrome, false otherwise
*/
public boolean isPalindrome()
{
boolean palindrome = true;
if(word.getReverse().equals(word)){
palindrome = true;
}
else{
palindrome = false;
}
return palindrome;
