Java BreakIterator current()用法及代码示例

java.text.BreakIterator类的current()方法用于获取单词行中最近文本边界的索引。它提供BreakIterator当前指向的文本的偏移量。

用法:

public abstract int current()

参数：此方法不接受任何参数。

返回值：此方法提供最近文本边界的索引。

下面是说明current()方法的示例：

示例1:

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

输出：

current position before calling next(): 0

current position after calling 1st next(): 4

current position after calling 2nd next(): 6

示例2:

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

输出：

current position before calling next(): 0

current position after calling 1st next(): 13

current position after calling 2nd next(): 13
