How to make an array without setting the size first?

[Ian Smith]

I want to create an array to store values from user input. The user input is in a while (choice=='y' || choice=='Y') loop. As long as the user keeps selecting Y/y at the end of the loop, they can enter more values and continue. I want to store the 2 values that are entered and a 3rd calculated value in an array. The user can stop after 1 value or keep going up to 100 iterations of the loop (if they so desire).

My original thought was to create 3 array variables but I am stuck trying to figure out the exact code needed to allow an array(s) to just grow, as needed. I do not want to preset the size of the array to any single value though. Any help in this manner would be appreciated.

You can use some collection frameworks for this.

What you're doing sounds a lot like an ArrayList or a Vector, both of which are collections.

I'd stick with the ArrayList, unless you require synchronization . But - I suspect that you aren't at the point of needing to know the difference in your training.

Work with what you've got, write a prototype, and if you have any questions about your code - ask them.
