    Hello ,
    I am having trouble with my code I am a beginner and I know I probably made a mistake somewhere but can't figure out where .
    -I want to only have 7 letters to output but I can't figure out what is wrong , Every time i type less than 7 letters I get an error
    - I want to have an hyphen between the 3 and fourth number but don;t know how to make it work .
    -How can I replace a space between an input words by nothing every time I have a space between a word It give me a zero

    In your code, replace Number1.length with Number.length() in the for loop. Then it works.

    With String[] Number1 = new String [7], you are making collection of 7 strings. Is this what you want? It is easier to make one string with 7 characters.
