Re: How to terminate if string is repeated

Insert all the Strings that the user enters in to the args[] string array, since this array is being passed to each successive call of main, So you will have a list of all entered keywords in this array.

In order to check for repetitions just check if the entered word is present in the args[] array.

But instead of calling the main recursively I recommend you delegate this responsibility to some other method and let that method call itself recursively.

I agree.
