Well, the piece of code in my class : 

  String sentence = "1. John," +
            "2. Mark," +
            "3. Sam";

And is logical that I have this output : 

1. John
2. Mark
3. Sam

, so I need to replace all commas to line breaks ( \n ) ;

Unless I have missed something, this is as simple as using replace to change the command toa newline character (\n):

String sentence = "1. John," +
                  "2. Mark," +
                  "3. Sam";
String newSentence = sentence.replace(",", "\n");

Depending upon environment, you may want to use a carriage-return\line-feed which would be "\r\n".

Here's a link to a few examples of using it.

You literally just replace , with \n:

String sentence = "1. John\n" +
        "2. Mark\n" +
        "3. Sam";
