Java CollationElementIterator primaryOrder()用法及代碼示例

java.text.CollationElementIterator類的primaryOrder()方法用於提供CollationElementIterator對象的每個Collison元素的主要組件。

用法:

public static final int primaryOrder(int order)

參數：此方法將排序規則元素作為整數格式的參數，必須為其找到主要成分。

返回值：此方法返回特定Collison元素的主要成分。

下麵是說明primaryOrder()方法的示例：

範例1：

// Java program to demonstrate 
// primaryOrder() 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 = "GeeksForGeeks"; 
  
        // creating and initializing 
        // RuleBasedCollator object 
        RuleBasedCollator rbc 
            = (RuleBasedCollator)(Collator.getInstance()); 
  
        // creating and initializing 
        // CollationElementIterator 
        CollationElementIterator cel 
            = rbc.getCollationElementIterator(test); 
  
        // for iteration 
        for (int i = 1; i <= test.length(); i++) { 
  
            // getting primary component of every elmenet 
            // using primaryOrder() method 
            int value 
                = CollationElementIterator 
                      .primaryOrder(cel.next()); 
  
            // display the reslut 
            System.out.println("primary order "
                               + "for order "
                               + i + " is "
                               + value); 
        } 
    } 
}

輸出：

primary order for order 1 is 89
primary order for order 2 is 87
primary order for order 3 is 87
primary order for order 4 is 93
primary order for order 5 is 101
primary order for order 6 is 88
primary order for order 7 is 97
primary order for order 8 is 100
primary order for order 9 is 89
primary order for order 10 is 87
primary order for order 11 is 87
primary order for order 12 is 93
primary order for order 13 is 101

範例2：

// Java program to demonstrate 
// primaryOrder() 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); 
  
        // for iteration 
        for (int i = 1; i <= test.length(); i++) { 
  
            // getting primary component of every elmenet 
            // using primaryOrder() method 
            int value 
                = CollationElementIterator 
                      .primaryOrder(cel.next()); 
  
            // display the reslut 
            System.out.println("primary order "
                               + "for order "
                               + i + " is "
                               + value); 
        } 
    } 
}

輸出：

primary order for order 1 is 84
primary order for order 2 is 97
primary order for order 3 is 85
primary order for order 4 is 87
primary order for order 5 is 0
primary order for order 6 is 89
primary order for order 7 is 87
primary order for order 8 is 87
primary order for order 9 is 93
primary order for order 10 is 101
primary order for order 11 is 0
primary order for order 12 is 70
primary order for order 13 is 71
primary order for order 14 is 72
