Question

Using eclipse, I have a file titled bad_words.txt in my project folder titled HackGSU. I want locate the file and read the contents of the file. I saw this answer how to read te

Answer 1

You probably should use backslash instead of slash:

p.concat("\HackGSU\bad_words.txt");

You can also try to type double backslash:

p.concat("\\HackGSU\\bad_words.txt");

Answer 2

If your resource is already in the classpath, you don't need to make use of relative paths with the File class. You can easily obtain it from the classpath like:

java.net.URL url = getClass().getResource("bad_words.txt");
File file = new File(url.getPath());

or even directly to an inputstream:

InputStream in = getClass().getResourceAsStream("bad_words.txt");

Since you have a static method use:

InputStream in = YourClass.class.getResourceAsStream("bad_words.txt");

Furthermore, as I mentioned it already in my comment:

p.concat("/HackGSU/bad_words.txt");

does not concat to p but returns a new concatenated String, because Strings are immutable. Simply use: p+="/HackGSU/bad_words.txt" instead

Answer 3

Looking at the error it doesn't look like you are getting the full path. Instead of

p.concat("/HackGSU/bad_words.txt");

Try

p = p.concat("/HackGSU/bad_words.txt");
