    Why use a double for the loop control variable?

    Can you copy the contents of the console window that shows the problem and paste it here?

    To copy the contents of the command prompt window:
    Click on Icon in upper left corner
    Select Edit
    Select 'Select All' - The selection will show
    Click in upper left again
    Select Edit and click 'Copy'

    Paste here.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    That's the Scanner leaving a linenend character in its buffer after the call to nextDouble().
    Call nextLine() to clear the lineend character after the call to nextDouble().
