this question has answer here: is java “pass-by-reference” or “pass-by-value”? 74 answers are arrays passed value or passed reference in java? [duplicate] 7 answers when passed array argument function, original array gets changed, array should not changed right? please correct me if wrong. below passed int x=10 argument change(int a) function. value of original int x got changed. so how same code affects array , int in different way? public class runy { public static void main(string [] args) { runy p = new runy(); p.start(); } void start() { long [] a1 = {3,4,5}; long [] a2 = fix(a1); int x=10; int y= change(x); system.out.println(y); system.out.println(x); system.out.print(a1[0] + a1[1] + a1[2] + " "); ...

i have example object: object foo { private def sayfoo = "foo!" } and want test private sayfoo method without following workarounds: 1. without defining package private 2. without defining protected , inheriting in test class i saw 1 possible solution extend privatemethodtester doesn't seem work objects classes. now, know some, if not many, not suppose test private methods rather public ones (api). nonetheless, still want test them. thx in advanced it cannot tested standard means. however, if need "cover" section of code, test methods use private method in implementation. indirect, granted, test code. for example, in class have method: def dontsaybar = { sayfoo() println("other processing...") } and "cover" code in private method if tested. p.s. rule of thumb if see code isn't showing in coverage run, don't need code.
