<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-GB" xml:lang="en-GB">

I am getting an error stating that 'word cannot be resolved to a variable' pointing to my return value. Why? Should I make a default String value for word before my while loop or something, like
String word = " ";
?
String getItRight(){//make sure the user enters the password correctly
Scanner input = new Scanner(System.in);
boolean repeating = true;
while(repeating){

I'm not sure why I'm getting these errors. They only begin to happen after the second if statement, and the subsequent if statements are formatted exactly the same.
The errors are marked by the comments in the code.
Java Code:
import java.util.*;
import java.io.*;
public class GazillionSongs {
public static void main(String[] args) throws FileNotFoundException {
System.out.println("Welcome to Java Song Collection!");
System.out
.println("This program sorts and filters large databases of popular songs.");

The error "cannot resolve to a variable". I get the error I just can't seem to fix the error.Presently I am working my way through the Oracle docs and that seems ok. Java for Dummies, Sams teach Yourself Java in 21 Days, plus my favorite Head First Java.

I am implementing a SSO using NTLM. The steps are:
Step1: Cliente ask for resource
Step2: Server ask for NTLM negotiation
Step 3: Client sends to the server NTLM type 1 message
Step4: Server sends back to the client NTLM type 2 message
Step5: Client sends type 3 message.
The problem I have is in Step 5, when the browser receives the type 2 message, it just stops displaying "IE cannot display the webpage" and sends nothing to the server.
I have checked that I am sending a correctly the type 2 message, using a sniffer I can see the NTLM type 2 message (challenge) and it is well formed (I have test also different flags configuration). I have test also with Firefox and the same behaviour. Server and client are in the same Domain.

I made a guess a number program but I am having issue figuring out a way that when a user enter's in nothing for the program to spit out a message saying "hey entering nothing doesn't work try again" then ask for input. I have done some research and from what I have found is to read the input in as a String rather than int, and use something like Integer.valueOf() to get the integer value but I am completely lost on how to apply that to my program here is my code
//import statements
import java.util.*; //for scanner class
// class beginning
public class Guess {
public static void main(String[] args ) {
//Declare variables area
int guess, secretNumber = (int) (Math.random() * 10 + 1), lowGuess,highGuess;

Basically I'm trying to code this program but I keep getting error can't be applied to given types. I know it has to do with my method trying to be called by an array, but I'm just kinda lost.
Write a program that prompts the user to input cash amounts and use a method to calculate the average amount for a week given 7 inputs of daily cash intake amounts for a cash register. Use an array to store the values. Recall that average is the sum of the values divided by the number of values. The method should take argument(s) of type double and return average weekly cash amount as a double.
Make sure you test your program using the test data given below and calls the averageCash() method defined above passing in the values. Verify that the input values are greater than or equal to 0. Negative numbers are not allowed. Output the values used and the averageCash value.
import java.util.*;
public class ArrayHandout {
public static void main(String args[]) {
int[] a=new int[6];
Scanner sc=new Scanner(System.in);
