How to create a method to return 1 or 0 without using conditions?

Question

I was asked a question in an interview to return 1 if provided 0 and return 0 if provided 1 without using conditions i.e if, ternary etc Just to give you and idea below code without if's: public int testMethod(int value){ if(value==0) return 1; if(value==1) return 0; return 0; } [`Java Fiddle`](http://www.tutorialspoint.com/compile_java8_online.php?PID=0Bw_CjBb95KQMbFJMXzlmZi1KZUk) **UPDATE:** Though @Usagi's Answer may seem the best fit with respect to the code I wrote .. but re-considering the question I re-analyzed the answers .. and @Sergio's answer seems the simplest and best fit ..

Answer 1

Depending on the OS and compiler, you might get away with something like "return !value". This technically returns TRUE or FALSE, but for some languages such as C the default numeric value of true is 1 and false is 0.
