Detect a new paragraph with one word

Question

I need to detect a new paragraph with one word from variable which was initialized be reading a text from a web site. For instance, a variable contains (it is printing this way):

hello

Are you sure about...

The resulting string must be

Are you sure about...

I do

String arr[] = message.split("\r");
StringBuilder sb = new StringBuilder();
for (String el: arr) {
    String[] temp = el.split(" ");
    if(temp.length > 1){
        sb.append(el).append("\r");
    } else {
        continue;
    }
}

But for some reason in production it does not do the job so the first word is still present in resultin string. What is the reason?

Perhaps your production system isn't using `"\r"` for its line breaks? — azurefrog, Aug 29 '16 at 18:16
Carriage return isn't newline. Carriage return simply goes back to the start of the line - the same line — smac89, Aug 29 '16 at 18:16
Perhaps a review of this related question would help - http://stackoverflow.com/questions/247059/is-there-a-newline-constant-defined-in-java-like-environment-newline-in-c — CodeMonkey1313, Aug 29 '16 at 18:19
Are you perhaps developing on Windows and your production on Linux or Mac? Windows uses CRLF for line endings (`\r\n`) and Linux/Mac use simply LF (`\n`). Like CodeMonkey1313 suggested try looking at this, [`System#lineSeparator()`](http://docs.oracle.com/javase/7/docs/api/java/lang/System.html#lineSeparator%28%29) — Captain Man, Aug 29 '16 at 18:26

New line character should be used instead of carriage. A simplified version of your code:

String arr[] = message.split("\n");
StringBuilder sb = new StringBuilder();
for (String el : arr) {
    if (el.trim().split(" ").length > 1) {
        sb.append(el).append("\n");
    }
}
System.out.println(sb.toString());
