    Default Java word unscrambler

    I just can't figure out whats wrong with this code. It compiles but just outputs no answer! The desired function is for a user to enter nicegroan for example, and for the java program to run through dictionary.txt and find the longest word it can make from the user input which in this case would be ignorance. Any help would be appriciated.

     
         import java.util.Scanner;
     
    public class countdowntwo
    {
     
    public static void main(String[] args){
     
            //instantiate an instance of FileIO    
            FileIO reader = new FileIO();
     
            //the code below shows how to load a file
            String[] contents = reader.load("C:\\dictionary.txt");
     
            //now you can process the contents of the file as a String array
     
            Scanner in = new Scanner(System.in);
     
            System.out.println("Insert your letters");
            String input = in.nextLine();
            char[] inputArray = input.toCharArray();
     
            for(int i = 0; i < contents.length; i++)//loop through dictionary array
            {
            	for(int j = 0; j < contents[i].length()-1; j++)//loop through contents of that array
    			{
            		char[] word = contents[i].toCharArray();//create a character array for each word in file
     
            		for(int k = 0; k < word.length-1; k++)//loop through character array
    				{
            			while(k<inputArray.length)//while its less then user input
    					{
            			   if(word[k]==inputArray[k])//if letters in word is equal to user input
    					    {
            				  word[j]=' ';
            				    for(int l = 0; l < word.length-1; l++)
    						   {
            					if(word[l]!= ' ')
    							{
            						break;
            					}
            					else
    							{
            						System.out.println("The word is "+contents[i]);
            						break;
            					}
     
     
            				}
            			}
            			}
     
            		}
            	}
     
     
            }
     
     
     
        }
    }

    outputs no answer!
    Try debugging the code by adding some println methods that print out the values of the variables used to control the logic and execution flow so you can see what the computer sees when it executes the code. The printout should show you where the logic is going wrong.


    The posted code does not compile because of missing class definitions.
    If you don't understand my answer, don't ignore it, ask a question.

    Then you will be able to:
