import java.text.*;
import java.util.*;
import java.io.*;
 
public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing BreakIterator
        BreakIterator wb
            = BreakIterator.getWordInstance();
 
        // setting text for BreakIterator
        // using setText() method
        wb.setText("Code Geeks");
 
        // getting the text being scanned by
        // using getText() method
        StringCharacterIterator text
            = (StringCharacterIterator)wb.getText();
 
        // display the result
        System.out.print("Retrieved text is : "
                         + text.first());
        for (int i = text.getBeginIndex() - 1;
             i < text.getEndIndex() - 2;
             i++)
            System.out.print(text.next());
    }
}

输出
