Java CollationElementIterator getOffset()用法及代码示例

java.text.CollationElementIterator类的getOffset()方法用于获取在CollationElementIterator当前指向的整理器上存在的项目的索引。

用法:

public int getOffset()

参数：此方法不接受任何参数。

返回值：此方法返回迭代器当前指向的元素的偏移量。

下面是说明getOffset()方法的示例：

范例1：

// Java program to demonstrate getOffset() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        // creating and initializing testString 
        String test = "Code Geeks 123"; 
  
        // creating and initializing 
        // RuleBasedCollator object 
        RuleBasedCollator rbc 
            = (RuleBasedCollator)(Collator.getInstance()); 
  
        // creating and initializing 
        // CollationElementIterator 
        CollationElementIterator cel 
            = rbc.getCollationElementIterator(test); 
  
        // setting offset to index 4 
        cel.setOffset(4); 
  
        // getting offset of cel 
        // using getOffset() method 
        int value = cel.getOffset(); 
  
        // display the result 
        System.out.println("current offset is "
                           + value); 
    } 
}

输出：

current offset is 4

范例2：

// Java program to demonstrate getOffset() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
  
        // creating and initializing testString 
        String test = "Code Geeks 123"; 
  
        // creating and initializing 
        // RuleBasedCollator object 
        RuleBasedCollator rbc 
            = (RuleBasedCollator)(Collator.getInstance()); 
  
        // creating and initializing 
        // CollationElementIterator 
        CollationElementIterator cel 
            = rbc.getCollationElementIterator(test); 
  
        // setting offset to index 4 
        cel.setOffset(4); 
  
        // calling next element 
        cel.next(); 
  
        // getting offset of cel 
        // using getOffset() method 
        int value = cel.getOffset(); 
  
        // display the result 
        System.out.println("current offset is "
                           + value); 
    } 
}

输出：

current offset is 5
