When I am using Console method in Eclipse its showing error - Exception in thread "main" java.lang.NullPointerException

Yes, if you run a Console application outside of the Eclipse environment it'll throw that. Google it - there's a way round this. I'll see if I can find a post I wrote about this exact behaviour in these Forum pages.

Here - that gives you some options.

There is a way of doing this inside the IDE but it is escaping me right now as it's 23:30 here and I've had a long day! Scanner gives a useful way of running the code without (as in outside; with-out; not unrequiring-of) the IDE, but you can use Console as long as you run within the scope of the Console. Google something like that and Stack Overflow will give you something to work with.

as i came across your question , i discover something useful to answer it, just follow this link https://teamtreehouse.com/community/why-doesnt-consoleprintf-or-consolereadline-work-in-the-eclipse-ide-i-get-a-null-pointer-exception, to get the right answer, that tells in IDEs like eclipse they use System.in and System.out object to give and receive info from users, so i hope you will discover the right method to use it in yout test. thanks a lot.
