urgent help! my while loop is not working

/**Counting the appearances of a given word in a text
We have seen how to read in and manipulate characters and character strings and how to use the classes String and StringTokenizer. Use these to read in a word and then other text from the keyboard. Count the occurrences of the word that you read in at the beginning. Your program should be case insensitive; this means that you should convert the original word to pure upper case OR lower case and compare each token that you separate to this same case using toUpperCase() or toLowerCase(). Your program should keep checking text until you type �The End� by itself on one line**/


import java.io.*;
import java.util.*;
//Inserts word into text and breaks the text into tokens
public class WordText{
String word = new String();
String text = new String();


//Allows user to enter input from the keyboard
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader keyb = new BufferedReader(isr);

//sets word

while(quit!="the end")

should be
while(!quit.equalsIgnoreCase("the end"))

[unyime inok]

the program doesn't drop out of the loop when a user enters "the end", even with equalsIgnoreCase().

[Michael Dunn]

It doesn't drop out of the inner loop if there are still occurrences of "xxx"
but it does quit OK when there are no more "xxx".

Your program doesn't seem to follow the specs at the top of your post,
here's a few lines, just add the 'count' method (if this is what you're
trying to do)

import java.io.*;
class WordText
{
  public WordText()
  {
    try
    {
      String searchWord = "";
      String searchText = "";
      int wordCount = 0;
      BufferedReader keyb = new BufferedReader(new InputStreamReader(System.in));
      System.out.print("Please enter the word to search for: ");
      searchWord = keyb.readLine();
      while(true)
      {
        System.out.println("Please enter some text, so that a search can be made for \""+
                                             searchWord+"\"\nor type 'the end' to quit");
        searchText = keyb.readLine();
        if(searchText.equalsIgnoreCase("the end"))
        {
          break;
        }
        //add method to count occurrences//<-----------------------------------------
      }
      System.out.println(searchWord+" was counted "+wordCount+" times");
    }
    catch(Exception e){e.printStackTrace();}
  }
  public static void main(String[] args){new WordText();}
}
