    Default how to delete first letter of string

    Here is my code:

     public static String[] guillotine( String[] inArray ) 
     
    {
     for (int i = 0; i < a.length - 1; i++){
             System.out.print(a[i].substring(1)); 
     }
    }
      String[] a = {   }; 
      String[] b = guillotine( a ); 
     
      System.out.println( b[  ] );

    Thanks.

    Firstly, these forums are not meant for us to plainly write out solutions for you, they are here to guide you.

    Second, you are using an array of Strings, which I don't think is the data type you are looking for since this would contain multiple strings, not characters. Without more information it's hard to know.

    Thirdly, your code won't compile which suggests you might be missing some basic fundamental parts of the Java language.

    If you have questions, go ahead and ask, but again we are not here to just give you a solution.

    Unless they plan on the array containing one character long Strings.
    String[] word = {"h", "e", "l", "l", "o"};
    But it would be nice if OP provided better/more information. It can be achieved with a single call to substring but it seems there is a recursion requirement to the assignment.

    Originally, I didn't have anything within the brackets. I'm supposed to put something in there. I think though, that since I'm filling in the blank, do I have to put in another "public static?" I mean, what sort of thing do I put in the brackets exactly? Is it a for-loop, if-statement, array...? I think the whole thing involves an array. Basially, if a = {"meat", "flat", "flukes"}, then it should be a = {"eat", "lat", "lukes"}.

    So yes, I'm using strings. I tried "substring()" but I couldn't get to the bottom of how to use it. Do I need to use "substring()" here? That's the conclusion I come to, but I don't think I'm doing it right.

    My idea (which I don't know how to implement) is, for each string in the array, to find the first letter of each string imputed and delete it automatically. Then it would print it.

    Which fundamentals am I missing?



    Hope that helps.

    Thanks, ghostheadx

    "substring()" but I couldn't get to the bottom of how to use it.
    Take a look at the API doc for the String class. Remember that Strings can't be changed. methods that operate on the contents return a new String with the changes
    Then write a short simple program that uses it.
    Print out the results.
    If you don't understand my answer, don't ignore it, ask a question.
