Help with String

[Felissa]

I have written a program that asks the user to input a five-letter word and then will return all valid three letter words from the original word. My problem is that I am getting nothing to print, I don't know if I am doing the comparison properly.

Code:

import java.io.FileNotFoundException;
import java.io.FileReader;
import java.util.Scanner;

public class ThreesFromFive 
{

	public static void rearrangeAndOuput() throws FileNotFoundException
	{
		String word = new String();
		String threeLetterWord = new String();
		StringBuffer wordBuffer = new StringBuffer();
		Scanner input = new Scanner(System.in);
		Scanner inFile = null;
		
		//0pens file to be read
		try
		{
			inFile = new Scanner(new FileReader("../JavaHomework/chapt29_18/threeletterwords.txt"));
		}//end try 
		
		catch (FileNotFoundException e) 
		{
			System.err.println("File not found.");
			System.exit(1);
		}//end catch
		
		System.out.print("Enter a five letter word:");
		word = input.next();
		if (word.length() != 5)
		{
			System.out.print("Please enter a five letter word:");
			word = input.next();
		}
		
		System.out.print("The three letter words that can be made from\n");
		System.out.print("the word you typed in is:\n");
		
		//create three letter words
		for (int i = 0; i < 5; i++)
		{
			
			for (int j = 0; j < 5; j++)
			{
				
				for (int k = 0; k < 5; k++)
				{
					//create new three letter word
					wordBuffer.append(word.charAt(i));
					wordBuffer.append(word.charAt(j));
					wordBuffer.append(word.charAt(k));
					threeLetterWord = wordBuffer.toString().toLowerCase();
					
					while (inFile.hasNext())
					{
					
						//check to see if word is valid three letter word
						if (threeLetterWord.equals(inFile.next()))
							System.out.printf("%s\n", threeLetterWord);
						
					}
					
					//re-initialize wordBuffer to create new word
					wordBuffer = new StringBuffer();
					
				}//end for
				
			}//end for
			
		}//end for
		
	}//end rearrangeAndOutput
	
	
	public static void main(String[] args) throws FileNotFoundException 
	{
		rearrangeAndOuput();
	}

}

Thanks

Instead of constructing all the permutations of 3 letter words instead can you not scan every word of the file containing 3 letter words and simply check if the 5 letter input contains all the characters in the 3 letter word.

Code:

 for each 3 letter word : word3
   for each character in word3 : ch
     check if input5 contains ch
   if all the characters of word3 are present in input5 print it

Thank you for the suggestion, it didn't work though. I think it has something to do with the way I'm reading in the file or the way I'm comparing the strings.
