Java Programming

Hello,
I'd like to remove ends of line from the string. I've tried:

    static final Pattern END_LINE_PATTERN = Pattern.compile("$+");
    
    strBuf.append(input);
    Matcher m = END_LINE_PATTERN.matcher(input);
    int startIndex = -1;
    int endIndex;
    while (m.find()) {
	startIndex = m.start();
	endIndex = m.end();
	if (endIndex == strBuf.length() - 1) break;
    }
    if (startIndex > -1) {
	strBuf.setLength(startIndex);
    }

For strings "hello\n" and "hello\r" it works properly, but for string "hello\n\n" I get first occurrence at index 6 (at second \n), so as the result I get "hello\n". For the string "hello\r\n" I get first occurrence at index 5 (it's OK), but the end index is 5 as well, and the next occurrence I get at index 7, which doesn't give me any sense.

Hope somebody can help me.
