Thread: Please Help I'm stuck

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
Please I am stuck if someone can help me.

Thank you so much

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.

ILan can you please tell me how I can do that
