Java中的 CollationElementIterator primaryOrder() 方法及示例

Java.text.CollationElementIterator类的primaryOrder()方法用于提供 CollationElementIterator 对象的每个 Collision 元素的主要组件。

句法：

public static final int primaryOrder(int order)

参数：此方法将排序规则元素作为整数格式的参数，必须为其找到主要组件。

返回值：此方法返回特定碰撞元素的主要组件。

以下是说明primaryOrder()方法的示例：

示例 1：

Java

// 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);
        }
    }
}

输出：

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

示例 2：

Java

// 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);
        }
    }
}

输出：

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
