Its very crude but will still work if you call processAccount() from another class with a main method |

Call me crazy but I think your code would look a lot cleaner if: 1) Instead of "if x == 1" you used switch/case statements  2) You ran your options in a while loop, reading the input and redirecting to a switch or outputting an error if the input isn't text or they pressed say, 5 for "exit". the way you have it now, and I haven't compiled your code (neither do I intend to  ), it seems all I will see is "press 1". Then after I am done with "1", you tell me to press "2" which isn't how a real-life software would probably work. Right now, it looks very linear. |

yea. There is even no exception handling so if i entered a string the whole program is gonna crash because of this " int x=input.nextInt(); " |

To show his mad java "skills" He probably just read an ebook off of google and/or just learned this in class so he decides to put fingers to keyboard and come up with a class without compiling it for himself to see if it makes the slightest of sense. Sorry to be harsh but the code sucks. I was actually only trying to be nice at first. Java is an OO language. The way he has it there, it looks more like paschal. In fact, this is the kind of code I call JINO (Java In Name Only) |

OK so my funny code caused quite a stir,well the code was written months ago and happened to be in my flash as at the time so i posted it,well i agree with ur views cos(1) the lack of: try( ) { System.out.print, int num=oui.nextInt(); } catch(inputmismatchexception mismatchexception) { System.err.print( "TRY ANOTHER VALID VALUE" ) int num, } the lack of the exception handling feature was a flaw(i was not used to it as at the time the code was written)'also switch statements tend to make ur code neater and more readable,agreed.as for my brother that did not know what the code was for it was meant to be an ATM demo with acc. opening features.YEWATIDE ur views ar agreed wit but next time exhibit more matured relations wit ur fellow programmers. |

@donkoleone I think you may have missed the point of the criticism being levelled at you. It appears you have made the same mistake many aspiring programmers make in concentrating on the language rather than first having a clear understanding of the principles of programming. What I mean is that in my opinion you would do well to fully understand the principles of Object Oriented Programming (OOP) first and then learn how to apply those principles in Java. Had you done so, I suspect your code would not have been so linear as you would have made more use of classes and also you probably would have included exception handling etc. |

donkoleone, Can you define maturity? If yes, could you look in the mirror and see how it applies to you? |

i still don't see the point of the code, other than using cases, or exception handling, there r tons of things wrong with it, The program is basically spitting back to the user what they enter, It only demonstrates the use of I/O in java, |

Hi you guys, should learn to be objective when you need to criticise someone. I believe the aim is to learn and not mess ourselves up. If I may add my comment. This code is a tutorial code, the type we wrote in those days of Basic and Wbasic. It is procedural of course to demonstrate the if else statement and probably introduction to the Scanner and printf classes (Java 5 new features.). Hope am right. If not, please donkoleone clarify. |
