it will return a string... the documentation says so. do this to conver teh string object to an int:
EDIT: based on bugzpodder recomendation.. which is the better way out.. |

parseInt is the way to go. if you look on the hand out you'll see. |

what packages do you need to import? That code does not look like any familiar code to me. based on the following i presumed it was javascript. you variables are not declared but directly defined. screen.write(""); is something i'm sure java does not have. anyways.. you might be using what is known as bsh or the bean shell. i don't know much of the bean shell syntax. but it's supposed to be the Java scripting language. Technically any valid java code is a valid beanshell code. but not the other way round. but if it is java that code won't compile. (as i said what packages do i need to import?) |

yeah... there should be a rule that when you post java code that implements non standart packages, please include all the "include..." lines so the rest of us wouldn't have to guess maybe rizzix should write it up, he knows Java better then I do |

yea i'd agree tony. there are far too many java-like scripting variants that look similar to java. it get's pretty confusing at times. I mean java code is 100% bean shell compatible yet not the other way round (i.e bsh code is not 100% java compatible). speaking of which do check out this awsome scripting language @ www.beanshell.org .. and don't be to hard on that dude, he probably got offended for some reason |
