Where are all the symbols!? Poor Java can't find them... :(
Hello! For my computer science class, I have to convert a program with global variables to a program with all instantiated variables. I tried... and, well, the program works. Java gets it! But, I do have 24 errors.
Here is my new code:
//Note: You need to change the input file to the one on your computer! import java.io.*; import java.util.StringTokenizer; import java.util.HashSet; public class VowlezRUs { //method variables private static FileInputStream inFile; private static InputStreamReader inReader; private static BufferedReader reader; public static void main (String args[]) throws IOException { //Methods initFile(); doStuff(); inFile.close(); } public static void initFile() throws IOException { //Data Input inFile = new FileInputStream ("D:\\My Documents...\\blooby.txt"); inReader = new InputStreamReader (inFile); reader = new BufferedReader (inReader); } public static void doStuff() throws IOException { int leftmostIndex; //Line can't be null for loop to execute String line = "start"; while (line != null) { //Data conversion into strings line = reader.readLine(); if (line == null) { break; } StringTokenizer strTkn; strTkn = new StringTokenizer(line); String word = strTkn.nextToken(); String suffix = strTkn.nextToken(); //TEST //System.out.print(word); //add vowels to set for comparing HashSet vowels = null; vowels = new HashSet(); vowels.add("A"); vowels.add("C"); vowels.add("S"); vowels.add("L"); //TEST //System.out.println(word); //Set output variables...

So you can see the string variables and such that I tried to incorporate into the new code, but I can't figure out what else I can do to get rid of the errors. Here is my error list, should you also require that to assist me:

Also, here is what consists of the text file I'm using for the input stream:
XQAC ZVM PDAE AV SNIC SY AAAB BB
Essentially, I am given a fictional word, and need to add a fictional suffix to the end. My main problem with the program, as you can see, is that I am having trouble declaring variables properly. If you would like the assignment prompt, please say so, as I would be happy to offer any documents that would help you help me!
Thank you in advance!
