public boolean isBoundary(int offset)

Parameter: This method takes offset as a parameter for checking if it is a boundary or not.

Return Value: This method provides true if the passed offset is boundary otherwise false.



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

Example 1:




// Java program to demonstrate isBoundary() method
  
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
        wb.setText("Code  Geeks");
  
        // checking for the boundary
        // by using isBoundary() method
        boolean status = wb.isBoundary(0);
  
        // display the result
        if (status)
            System.out.println("offset is a boundary");
        else
            System.out.println("offset is not a boundary");
    }
}
Output:
offset is a boundary

Example 2:




// Java program to demonstrate isBoundary() method
  
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
        wb.setText("Code  Geeks");
  
        // checking for the boundary
        // by using isBoundary() method
        boolean status = wb.isBoundary(2);
  
        // display the result
        if (status)
            System.out.println("offset is a boundary");
        else
            System.out.println("offset is not a boundary");
    }
}
Output:
offset is not a boundary
