Java 中的排序器 primaryOrder()方法，带示例

原文:https://www . geeksforgeeks . org/collectionelementiterator-primaryorder-method-in-Java-with-examples/

类的 primaryOrder() 方法用于提供 CollationElementIterator 对象的每个碰撞元素的主要组件。

语法:

public static final int primaryOrder(int order)

参数:该方法以整数格式的排序元素作为参数，必须找到其主成分。

返回值:该方法返回特定碰撞元素的主分量。

以下是说明 primaryOrder() 方法的示例:

例 1:

Java 语言(一种计算机语言，尤用于创建网站)

// 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);
        }
    }
}

Output: 

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

例 2:

Java 语言(一种计算机语言，尤用于创建网站)

// 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);
        }
    }
}

Output: 

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
