    Default Without using reverse method

    how can I reverse a word "beautiful" without using Reverse() method?

    I need to know because I'm going to make it as a basis for VB and C. I'm going to make a comparison. It will be my report that's why I really need to understand it.

    I checked on some sites but they are using Reverse() Method.

    Thanks a lot.

    iterate over the string from the end to the beginning and use the charAt method and add these characters to the end of a new empty string / or use a stringbuilder

    ... or do it the recursive way:

    - if a String contains at most one character the String is its own reverse, otherwise:
    - append the first character of the String to the reverse of the rest of the Sitrng.

    kind regards,

    Here's what you want, isn't it?

    Java Code:
    String s = "some text";
    StringBuilder sb = new StringBuilder();
    for (int i = s.length() - 1; i >= 0; i--) {
        sb.append(s.charAt(i));
    }
    System.out.println(sb.toString());
