Java BreakIterator next(int)用法及代碼示例

java.text.BreakIterator類的next()方法用於從當前邊界(通過調用current()方法檢索的邊界)獲取第n個下一個邊界的索引。它提供了由BreakIterator指向的當前邊界之後或之前的邊界第一個字符的偏移量。

用法:

public abstract int next(int n)

參數：它使用n(要跳過的邊界數)作為參數。如果n為正，它將向前跳過邊界，否則向後跳過。

返回值：此方法提供當前邊界的第n個下一個邊界的索引。

下麵是說明next()方法的示例：

示例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(2); 
  
        // display the result 
        System.out.println( 
            "\ncurrent position after"
            + " calling 1st next() : "
            + next); 
  
        // calling next method 
        next = wb.next(-1); 
  
        // display the result 
        System.out.println( 
            "\ncurrent position after"
            + " calling 2nd next() : "
            + next); 
    } 
}

輸出：

current position before calling next() : 0

current position after calling 1st next() : 6

current position after calling 2nd next() : 4

示例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("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(1); 
  
        // display the result 
        System.out.println( 
            "\ncurrent position after"
            + " calling 1st next() : "
            + next); 
  
        // calling next method 
        next = wb.next(2); 
  
        // display the result 
        System.out.println( 
            "\ncurrent position after"
            + " calling 2nd next() : "
            + next); 
    } 
}

輸出：

current position before calling next() : 0

current position after calling 1st next() : 4

current position after calling 2nd next() : 11
