    Default compare two strings to see if they end with the same sub-string

    Hi,

    I need to write some java code that will compare two strings and if they both end with the same sub-string.

    eg.

    String NAME
    String TEST

    if (the last 7 characters of the string are equal) {

    do something

    }


    any help appreciated!

    thanks

    Default Re: compare two strings to see if they end with the same sub-string

    Search the API for THE string function String.endsWith() and compare them(Edith THE equals)
    If you juist want to compare you dan compare substrings like this:
    stringa.substring(stringa.length()-1-7, stringa.length()).equals(stringa.substring(stringa.length()-1-7, stringb.length()))
    Dont droget to check first if the strings arent shorter then 7

    Or you can do:
    int len = stringB.length();
    if (len >= 7 &&  stringA.endsWith(stringB.substring(len-7, len)) {
    ....
    }
