    Default How to subtract from the total length of an array

    I have an array named shop which has a length of 10.

    char shop[][] = new char[10][10]
    so my shop.length is 10

    if (colshop == 9)
    In the above line, I have hard-coded the value to be 9, Instead, I want to subtract 1 from shop.length.

    If I do if (colshop == (shop.length - 1)) ,it is not working.Please be patient as I am new to java. How do I do it so that I get the value of 9 as i do not want to hard code the value 9

    It works for me. You must be having other problems. But you didn't really provide much information. Providing a few lines of code out of context does not help anyone understand the real issue.
