<0> i just need to know which is the popular
<1> I've used Hypersonic, MySQL, PostgreSQL, SQL Server, Oracle, and Access. My personal favorite is PostgreSQL.
<2> Your Queen is Back
<3> uhg. tomcat won't start
<3> this is getting frustrating
<4> Hey..can somebody please tell me why this is not working (I've explained in the paste): http://www.pastebin.ca/332128
<3> james_mil: what's it doing?
<4> It keeps returning the prices WITH the '.0' even when it shouldn't
<3> priceIntVal won't end with ".0" because it's an int
<3> so every time that runs, it'll run the else statement instead.. appendign the prices double
<4> sorry..
<4> hmm
<4> evulish.. do you mean I need to change the intValue() method to a doubleValue() method ?
<3> er
<3> i don't know what you're trying to accomplish, exactly
<4> did you read my comments in the paste?
<3> oh. then yes, use doubleValue i guess
<4> ok i changed that but I got NumberFormatException at this line: int pricesOne = Integer.parseInt(priceIntVal);
<3> what are you doing..
<3> why are you changing it to an int
<4> because i have a textfield, that allows the user to enter an Int or a Double, and when data is entered, it is added to the ArrayList as a double, so an Int would end in .0 and a Double would end in .1-9. So this if statement is checking if it is an Int or a Double, and I want to display it exactly as the user entered (as an Int or as a Double)
<4> hope you understand that
<3> what if they entered 20.0?
<4> then its an Int
<3> but they entered it as a double
<4> Yea, but they intended on entering it as 20 - as it is 20.0 - so my program will display 20
<4> hopefully
<3> and it won't display exactly as they entered it if they enter 20.0
<4> Yes in that case no it wont...but it will still display 20, which is what i want
<4> is my if statement structured wrong?
<3> if (d.doubleValue() == (int)d.doubleValue()) { /* int */ } else { /* double */ }
<3> i think that'd work
<5> I want to enter 2.0.0
<3> you would!
<5> Of course!
<5> I like to be difficult.
<3> Doubledouble!
<4> Thanks evulish :)
<6> hello
<4> How can i validate a JTextField so it only accepts an Int or Double ? Any methods/tutorials to use?
<6> int or Integer, double or Double
<4> erm...all of them probably...just NOT a String
<6> try { Double.parseDouble(myString)}{catch( NumberFormatException){}
<3> try { Double d = new Double(str); } catch (Exception ex) { try { Integer i = Integer.parseInt(str); } catch (Exception e) { return false; } }
<6> uh huh
<6> there is no need to do it also for the ints
<3> oh, good point
<4> right thanks
<4> so are you saying if NumberFormatException is thrown, then a String has been entered, and therefore an error? Correct? But how do i check if the exception has been thrown or not
<3> that's what the catch does
<4> oh ye lol
<4> :P
<4> thanks
<3> throw->catch
<3> pretty simple analogy there
<4> lol yep
<4> cheers again
