Few questions on over riding.

I am interiting a method openRead from another class, the method is to be overridden so that the scanner class uses the provided delimiter pattern, which is referenced. I need to make use of the scanner class useDelmiter method

method from another class

[code] public boolean openRead() throws FileNotFoundException { sc = new Scanner(new File(fileName));

if (fileName != null)
{
     return true;
}
else
{
    return false;
}

} [/code]

delimiter

[code] protected final String DELIMITERS = "[\s[^'a-zA-Z]]"; [/code]

I'm at a loss to how i over ride this using the constant delimiter.
