we have application displays kind of map. swing application draw set of java.awt.shape s java.awt.graphics2d#draw(shape) , fine. and now, have extend app allow our users editing (moving shapes on) map. there no translate or move methods on java.awt.shape s. can't change position ( java.awt.point ) of shape. i have tried override java.awt.shape#getpathiterator in order apply translation matches shape position. it's tricky because method accept transformation have merge , because correct pathiterator should start @ (0, 0) because relative shape position. and anyway, won't work because seems graphics2d don't use method draw java.awt.shape . so now, i'm feeling bit lost. solution let shapes drawn themselves, have rewrite part of application. that's not problem have know best solution : find trick move java.awt.shape seems best solution can't figure how that. change app have self drawing shapes nice have compute myslef contains , other

this question has answer here: leading 0 in javascript 3 answers var value = 05000; var addvalue = 1; if calculate value + addvalue , it's calculating wrong value var result = value + addvalue;// it's return value 20481 see below image quick watch result but if give value 5000( without 0 before value), it's calculate correct . why? putting 0 before number makes octal number literal. interpreted in base 8. for reason - not put leading zeros before numbers. doesn't intend . if ran code in strict mode , you'd have gotten error instead: uncaught syntaxerror: octal literals not allowed in strict mode.
