code:

if (inLine.indexOf(" ") < 0) singleWord = inLine; else {       String [] sp = inLine.split (" ");       singleWord = sp[0]; }

Note: Untested

errrr that's not what he wants.. you're reading the entire line, he wants to just read one token.

yeah but why cant we just read a line then break it down? Anyways, is it possible to read just 1 word?

You certainly can read a line and then split it on a given delimiter (like " "). You will want to research "regular expressions".

If you have the ability to use Java 1.5.0.x you will want to research the Scanner class.

i just want to read the first word then store it in an array then store the word after that in the same line so on and so forth and if you can how do you read characters from a data file

[Spastic]

string.substring(string.indexOf("a char"), string.indexOf("another char"));

or sumthin like that might work?

The best way to do this is what MysticVegeta said and use foo.split("\\s") and it stores each word in the array sepertally...

Personally, I would read the line, and than use a string tokenizer (using spaces as the seperator) and get that first word, save it into a variable, and do whatever you need to do with it. hope this helps
