    Default I can't get useDelimiter to cooperate

    I am working on a Java project and I am trying to get useDelimiter to remove everything except the text in between "=" and ",". For example, on the first line of the file I would like to keep "ThermostatNight".

    This is what the text file looks like:

    Event=ThermostatNight,time=0

    Event=LightOn,time=2000


    I've been able to do the exact opposite using this code:

    s.useDelimiter("=(.*?),");

    Is there any way I can tweak this to do the opposite?

    Default Re: I can't get useDelimiter to cooperate

    Please provide more information on your project (preferably an SSCCE), as we can only guess what the useDelimiter method refers to. I'm in a guessing mood so I'll take a shot: you are referring to the Scanner method useDelimiter, in which case this is the delimiter. If you wish to capture groups and have more fine tuned parsing, I recommend reading Lesson: Regular Expressions (The Java™ Tutorials > Essential Classes). You could also use the methods of the String class to accomplish a same task
