Java + How to find a carriage return in a string value

Question

How can I find a carriage return in a string value? I have implemented it following manner, but for long String values some times it may not works. Thanks.

String value = "carriage\n return\r\n in\n a\r\n string\n" 

for(String line : value.split("\n")) {
    if(line.contains("\r")) {
       System.out.println("Carriage return found");
    }
}

What exactly happens? Can you show an example of a long string with the unexpected result? — swinkler, May 28 '15 at 09:13

Following this post : Difference between \n and \r? I think you can do the split like that :

String value = "carriage\n return\r\n in\n a\r\n string\n";

    for (String line : value.split("\n|\r"))
        if (!line.trim().isEmpty())
            System.out.println("Carriage return found:" + line.trim());

Output :

Carriage return found:carriage
Carriage return found:return
Carriage return found:in
Carriage return found:a
Carriage return found:string
