How to divide a sentence contains comma in middle into part Java?

Question

How can I divide a sentence like "He and his brother, are playing football." into few part like "He" , "He and", "and his", "his brother", "brother, ",", are", "brother playing" , "playing football", "football." and ".". Is it possible to do that by using Java?

String[] words = "He and his brother , are playing football .".split("\\s+");
System.out.println(words[0]);
    for (int i = 0, l = words.length; i + 1 < l; i++){
    System.out.println(words[i] + " " + words[i + 1]);  
}
String s = words[words.length-1];       
System.out.println(s.charAt(s.length() - 1));

This is the code I have done problem is "," inside the sentence must be separate with the word like "brother," must put as this "brother ," only will work. Any solution?

your split is pretty inconsistent, first you have `"brother, "` where you don't treat comma as a word and then you have `", are" where you do. Although it can be done, you might have to have edge cases for commas and full stops — Mateusz Kowalczyk, Jun 23 '12 at 05:39
So the only thing wrong with your code is that it gives you `brother ,` instead of `brother,`? — cklab, Jun 23 '12 at 05:59
The String in the sentence is `"He and his brother, are playing football."` then it will not get the result I want. If the string is `"He and his brother , are playing football ."` only will get the result. Any clue? — cchua, Jun 23 '12 at 06:07

Change this:

String[] words = "He and his brother , are playing football .".split("\\s+");

to:

String[] words = "He and his brother , are playing football .".split("[\\s+,]");

This will take care of the , , that is, you won't get brother,, instead you will only get brother. It will split on the occurence of a comma too.

You probably want to preserve the delimiters. Have a look at this : http://stackoverflow.com/questions/275768/is-there-a-way-to-split-strings-with-string-split-and-include-the-delimiters – Kazekage Gaara Jun 23 '12 at 08:31
`String[] words = "He and his brother, are playing football.".split("(?!^)\\b"); System.out.println(words[0]); for (int i = 0, l = words.length; i + 1 < l; i++){ System.out.println(words[i] + " " + words[i + 1]);} String s = words[words.length-1]; System.out.println(s.charAt(s.length() - 1));}` I cant get the result I want to? any problem with my code – cchua Jun 23 '12 at 08:46
