Which of the following type of a variable is volatile?
This question is pretty weirdly formed so i will stop the poll and explain it more clearly.
Sometimes we use variables in loops and in parallel execution (so variable is accessed and changed by different threads). Compiler tends to do some optimizations on our variables and cache their value so they could be accessed faster. But in parallel execution, caching variables values is not smart thing to do, because one thread might not see changes done by some other thread. That' why we use volatile keyword, to tell the compiler that the value of a variable must never be cached as its value may change outside of the scope of the program itself (for example in embedded systems, some variables can be changed by external processes and our program need to be aware of change at any point of time).
I guess that's the reason why "mutable variable" is the right answer, but other answers could be ambiguous. I hope this explanation was clear enough. If you have any questions feel free to contact me.

Top 15 Data Structures and Algorithm Interview Questions Answers for Java Programmer
Data structures and algorithm questions are an important part of any programming job interview, be it a Java interview, a C++ interview, or any other programming language. Since data structures are core programming concepts, it's mandatory for all programmers, to know basic data structures like the stack, linked list, queue, array, tree, and graph. Though trees and graphs are on the tougher side, I still see programmers get familiar will all these. This is a combined list of questions from the various data structures e.g. array, linked list, stack, or queue. It includes some coding questions as well, which gel with data structures.
