Is there a equivalent of strncpy() in Java?

Perhaps you could use String.trim(). This returns a new String with all whitespace removed from both ends of the source String. Whitespace here is the same as defined by the Character.isSpace() method: horizontal tab, newline, form feed, carriage return, and, of course, space (' '). Remember that this returns a new String. Since String is an immutable object, you cannot change its contents.

    String s = <your string>
    s = s.trim();

If you want to just remove carriage return, you might consider something like:

    String s = <your string>
    int crIndex = s.indexOf("\r");
    s = s.substring(0, crIndex);

This will take a substring of the original String that contains everything from the beginning of the String up to but not including the index of the first carriage return character. Of course, everything after the carriage return is discarded as well.

If you really want to remove just carriage returns and leave everything else intact, you might consider this:

    String s = <your string>
    StringBuffer buf = new StringBuffer(s);
    for (int index = buf.length() - 1; index >= 0; --index) {
        if (buf.charAt(index) == '\r') {
            buf.deleteCharAt(index);
        }
    }
    s = buf.toString();

If you want to remove just the last occurrence of carriage return, break the loop after deleteCharAt().

There is also a rather inefficient way of doing it with StringTokenizer but I doubt that it would be necessary to go to that length.

I was typing my comment when imladris posted so I didn't see his answer. Keep in mind that the carriage return and newline pair are usually seen in that order. As a result the posted answer will remove the last character from the String which is most likely going to be newline, not carriage return.

Playing around a little more, the simplest solution with the least side effects is likely to be String.replace():

    String s = <your string>
    s = s.replace('\r', '');

This will return a new String with all carriage returns removed.

Imladris solution worked fine.

Jim, thankyou for such detailed description on strings. I tried your solutions and they worked too.

Theta.
