    Default Pattern matching via regular expression

    I have to match all lines having the words 'Current configuration' anywhere in the line(beginning/end/middle)

    Then in Pattern.matches(regExp, line), what must be the regExp?
    regExp = "^Current configuration" is not working.

    Thanks in advance,
    Kakoli

    the Pattern.matches(...) must match the entire String. I'm not sure why you have the carrot, ^, in your regex. Consider adding some wild cards on both sides of your String though.

    Sorry, a correction.
    I have to match all lines having the words 'Current configuration' only at the beginning of the line.

    Then in Pattern.matches(regExp, line), what must be the regExp?
    regExp = "^Current configuration" is not working.

    If the line only has Current configuration, then your text should work, but if there's text afterward, it needs to be included.

    regExp = "^Current configuration.*";
    or some such.
