Win Detection For Hangman Game Not Working?

I'm almost finished with a program to simulate a Hangman game, but I can't figure out why my method of Win Detection (Having a counter variable corLetters which is incremented every time a correct letter is printed, and then including the if-statement:

if(corLetters == word.length())

followed by the actions to notify the user of a win isn't working.

For reference, this occurs:

Followed yet again by "What letter do you guess?" and so on, with every guess from there out registering as incorrect. Here are my classes:

My Main Class:

import java.util.Scanner;
import java.util.Random;

public class Main 
{

    public static void main(String[] args) 
    {
        Hangman manHang = new Hangman();    
    }

}

My Hangman Class:

import java.util.Random;

    String[] Bank = {"consider","minute","accord","evident","practice","intend","concern","commit","issue","approach","establish","utter","conduct","engage","obtain","scarce","policy","straight","stock","apparent","property","fancy","concept","court","appoint","ambiguous","arbitrary","alliteration","arrogant","benevolent","belligerent","boycott","cynical","connotation","cessation","contemporary","craving","grandiose","gratuitous","guile","harbinger","impetuous","incandescent","indigent","inexorable","injunction","insipid","insurgent","languish","magnate","abjure","abrogate","abstemious", "acumen", "antebellum","auspicious","belie","bellicose","bowdlerize","chicanery","chromosome","churlish","circumlocution","circumnavigate","deciduous","deleterious","diffident","enervate","enfranchise","epiphany","equinox","evanescent","expurgate","facetious", "fallacious"};
    String word;//Stores the random word used
    int incGuessCount = 0;
    int corLetters = 0;
    boolean[] lettersFound;//Used to mark which letters have been found
    String guessedLetter=" ";//Used to store guesses
    boolean gameOver = false;


    public Hangman()
    {
        r = new Random();
        get = new GetData();
        word=Bank[r.nextInt(Bank.length)]; //Selects a random word and assigns word the value
        lettersFound = new boolean[word.length()]; //Creates a boolean array the length of the word


        do

Also, the GetData Class:

import java.util.Scanner;

public class GetData
{ 
  private Scanner input; 

  public GetData()//Produces a scanner to take in input
  { input = new Scanner(System.in); } 

  public String aWord()//Gets the input as a guess/string
  { return input.next(); } 

  public int aNumber()//Gets the input as a number
  { return input.nextInt(); }

}

Thanks :)
