public abstract int next()

Parameter: This method does not accept any parameter.

Return Value: This method provides the index of next boundary following the current boundary.



Below are the examples to illustrate the next() method:

Example 1:




// Java program to demonstrate next() method
  
import java.text.*;
import java.util.*;
import java.io.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing with zero
        int current = 0, next = 0;
  
        // creating and initializing BreakIterator
        BreakIterator wb
            = BreakIterator.getWordInstance();
  
        // setting text for BreakIterator
        wb.setText("Code  Geeks");
  
        // getting the current text boundary
        current = wb.current();
  
        // display the result
        System.out.println(
            "current position before"
            + " calling next() : "
            + current);
  
        // calling next method
        next = wb.next();
  
        // display the result
        System.out.println(
            "\ncurrent position after"
            + " calling 1st next() : "
            + next);
  
        // calling next method
        next = wb.next();
  
        // display the result
        System.out.println(
            "\ncurrent position after"
            + " calling 2nd next() : "
            + next);
    }
}
Output:
current position before calling next() : 0

current position after calling 1st next() : 4

current position after calling 2nd next() : 6

Example 2:




// Java program to demonstrate next() method
  
import java.text.*;
import java.util.*;
import java.io.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing with zero
        int current = 0, next = 0;
  
        // creating and initializing BreakIterator
        BreakIterator wb
            = BreakIterator.getWordInstance();
  
        // setting text for BreakIterator
        wb.setText("GeeksForGeeks");
  
        // getting the current text boundary
        current = wb.current();
  
        // display the result
        System.out.println(
            "current position before"
            + " calling next() : "
            + current);
  
        // calling next method
        next = wb.next();
  
        // display the result
        System.out.println(
            "\ncurrent position after"
            + " calling 1st next() : "
            + next);
  
        // calling next method
        next = wb.next();
  
        // display the result
        System.out.println(
            "\ncurrent position after"
            + " calling 2nd next() : "
            + next);
    }
}
Output:
current position before calling next() : 0

current position after calling 1st next() : 13

current position after calling 2nd next() : -1
