原文:https://www . geesforgeks . org/rulesbasedcollator-getcollationkey-method-in-Java-with-example/

Java . text . rulesbasedcollator 类的 getCollationKey() 方法用于获取从传入的字符串转换而来的位序列。 语法:

public CollationKey getCollationKey(String source)

参数:该方法接受字符串对象作为参数。 返回值:该方法返回从传递给它的字符串转换而来的一系列位。 以下是举例说明 getCollationKey() 方法: 例 1:

Java 语言(一种计算机语言，尤用于创建网站)

// Java program to demonstrate
// getCollationKey() 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);

            // getting sereis of bits
            // using getCollationKey() method
            CollationKey key
                = col.getCollationKey("Geek");

            // display result
            System.out.println(
                "Series of bits are :- "
                + key.getSourceString());
        }

        catch (ClassCastException e) {

            System.out.println("Exception thrown : " + e);
        }
        catch (ParseException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output: 

Series of bits are :- Geek

例 2:

Java 语言(一种计算机语言，尤用于创建网站)

// Java program to demonstrate
// getCollationKey() 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);

            // getting sereis of bits
            // using getCollationKey() method
            CollationKey key
                = col.getCollationKey("G_f_G");

            // display result
            System.out.println(
                "Series of bits are :- "
                + key.getSourceString());
        }

        catch (ClassCastException e) {

            System.out.println("Exception thrown : " + e);
        }
        catch (ParseException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output: 

Series of bits are :- G_f_G
