Thread: Primitive text editor

Hi, I need to code a primitive text editor for school that can edit text files with the following methods:

1. String spellCheck () // finds the first occurrence of spelling error and returns the misspelled word. If no word is misspelled returns "Spell Check Passed".
2. void spellCheckAll() // find all misspelled words and output them to the screen.

These methods are supposed to use a text file of some 10,000 words as their "dictionary." The methods will need to be applied to long text files (300+ page books). I was planning on representing the text files as huge Strings, but I'm not sure how I would search through them word by word to compare to my dictionary list. I could change the way that I represent the files in memory, but Strings seem to be the most convenient data structure for the other methods I need for the editor. Can anyone help?

Thanks for your help

I know how to read and write files line by line, just not word by word. I guess I could search for blank spaces and create strings from whatever's in between. It just seems like there must be an easy way to scan a string word by word.

Use Java swing as desktop application
Use Java + GWT plugin as web text editor application

File inputFile = new File(commandFile);
RandomAccessFile raf = new RandomAccessFile(inputFile, "r");
String theLine = raf.readLine();

while (theLine!= null)
{
//whitespace before and after the string is removed.
theLine = theLine.trim();
//split the current line. Put each token into array.
String [] tokens = theLine.split("\\s+");
