Java BreakIterator isBoundary()用法及代码示例

java.text.BreakIterator类的isBoundary()方法用于检查传递的偏移量是否为边界。

用法:

public boolean isBoundary(int offset)

参数：此方法将offset作为参数检查其是否为边界。

返回值：如果传递的偏移量是边界，则此方法提供true，否则提供false。

下面是说明isBoundary()方法的示例：

示例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"); 
    } 
}

输出：

offset is a boundary

示例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"); 
    } 
}

输出：

offset is not a boundary
