Java RuleBasedCollator getCollationElementIterator(CharacterIterator)用法及代碼示例

java.text.RuleBasedCollator類的getCollationElementIterator()方法用於獲取給定字符迭代器對象的歸類元素迭代器的對象。

用法:

public CollationElementIterator getCollationElementIterator(CharacterIterator source)

參數：此方法接受字符迭代器對象作為參數。

返回值：此方法返回給定字符串的歸類元素迭代器的對象。

下麵是說明getCollationElementIterator()方法的示例：

範例1：

// Java program to demonstrate 
// getCollationElementIterator() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initializing 
            // new simple rule 
            String simple 
                = "< a < b < c < d"; 
  
            // Creating and initializing 
            // new RuleBasedCollator Object 
            RuleBasedCollator col 
                = new RuleBasedCollator(simple); 
  
            // Creating and initializing 
            // StringCharacterIterator Object 
            StringCharacterIterator obj 
                = new StringCharacterIterator("Geeks"); 
  
            // getting CollationElementIterator Object 
            // for the given String 
            // using getCollationElementIterator() method 
            CollationElementIterator key 
                = col.getCollationElementIterator(obj); 
  
            // display result 
            System.out.println( 
                "CollationElementIterator is:"
                + key); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
        catch (ParseException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

輸出：

CollationElementIterator is:java.text.CollationElementIterator@7d4991ad

範例2：

// Java program to demonstrate 
// getCollationElementIterator() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initializing 
            // new simple rule 
            String simple 
                = "< a < b & a < c"; 
  
            // Creating and initializing 
            // new RuleBasedCollator Object 
            RuleBasedCollator col 
                = new RuleBasedCollator(simple); 
  
            // Creating and initializing 
            // StringCharacterIterator Object 
            StringCharacterIterator obj 
                = new StringCharacterIterator("ABCDEF"); 
  
            // getting CollationElementIterator Object 
            // for the given StringCharacterIterator Object 
            // using getCollationElementIterator() method 
            CollationElementIterator key 
                = col.getCollationElementIterator(obj); 
  
            // display result 
            System.out.println( 
                "CollationElementIterator is:"
                + key); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
        catch (ParseException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

輸出：

CollationElementIterator is:java.text.CollationElementIterator@7d4991ad
