    Re: Code for Plotting 2D graphs

    You can connect Java via USB / serial, but you might need to give up any hope of "Write Once Run Anywhere". I wrote a little helper in Java for a bad oscilloscope I bought once here:

  2. Re: Wondering if there's a way to make this more efficient.

    Remember if your function argument is int or smaller and your function return value is int or smaller, that there's *by definition* a static alternative on reasonably common hardware. Your "boolean...
  3. Re: How to update the status of a java application from outside mail

    You mean a link like a "Please click here to confirm your registration"? That would usually be a http URL, so "m/c A" (no weird abbreviations next time, please) would have to run an HTTP server on a...

    Re: edit .conf file in /etc linux (java SE)

    You may need to read the response for the request to be sent. I'm fairly sure it's a 'lazy' process. Read the API docs for HttpUrlConnection - I think reading a response header or the response body...
  5. Re: Main method/ class problem. I can't run any script!

    Your Test.java source file contains a class called "Hello" - that's wrong, it should be a class called "Test". If you want its full class name to be test.Test, you should have a package declaration...
  6. Re: Question about obtaining information from a pulse oximeter for program

    Oh! That was a useful post - I just happen to be working on something a bit like cosm and wasn't aware of the site :-L

    I'd hesitate to recommend going down the Arduino route, unless you're...
  7. Re: Question about obtaining information from a pulse oximeter for program

    I've used USB-plugged devices from Java in the distant past - it does work. The problem you'll face is how well documented the USB interface is for whatever device you use - reverse engineering an...

    Re: String question

    I've never used Scanner, but a quick glance at the API doc for the class makes me think that 'hasNext' and 'nextLine' is not a good combination. 'hasNext' and 'next' seem better matched but not...

    Welcome to the forum

    With Java? I think Java's great, but it wouldn't be my first choice for "building a website" if I was "new to programming in any language". Are you sure you're not thinking of...

    Re: java.lang.outOfMemory heap space

    How about providing some more information? What exactly are you doing? A copy-pasted stack trace is always more useful than "i got the error like". You could let us know what platform you're using...

    [SOLVED] Re: Help with password generation

    You just need to re-read the API documentation for Random. The constructor you're using doesn't do what you think it does. Nor does Random.nextInt(). The fix is to select the correct constructor and...

    Re: Java socket corruption

    The way the data starts out 'bad' but ends up ok makes me think your problem is at source - and probably something to do with some bit-serial code somewhere. If you're using a Java Socket as your...

    Re: Java socket corruption

    Like I've already said more than once: I don't think there's anything wrong (that would cause the problems you report) with your Java code.

    Re: Java socket corruption

    That's not what I meant - what I mean is "what is offering port 7000" on your PC? I see in one of your programs that you open a ServerSocket on port 7000, but I don't understand why you'd read...
