BreakIterator isBoundary() method in Java with Examples

The isBoundary() method of java.text.BreakIterator class is used to check if the passed offset is boundary or not.

Syntax:

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
