String manipulation is one of the easiest process in Java, yet confusing sometimes. There are many build-in methods available with String class itself. Manipulating words in a String can be done by using java.text.BreakIterator. BreakIterator can be used to find the location of boundaries in text. The below example shows how to break a String into words.

import java.text.BreakIterator;

BreakIterator wordBreaker = BreakIterator.getWordInstance();
String str = "life is good";
wordBreaker.setText(str);
int end = 0;

for(int start = wordBreaker.first();
(end= wordBreaker.next()) != BreakIterator.DONE; start=end){
String word = str.substring(start, end)
//System.out.println(word);
}

The code above becomes useful, when we need to get a list of words in a String, to capitalize first letter in each word, to get first letter of each word etc.


Hope this helps!
