Java 中的排序器等于(对象)方法，示例

原文:https://www . geesforgeks . org/collator-equalsobject-method-in-Java-with-example/

java.text.Collator 类的 equals() 方法用于检查两个 Collator 对象是否相同。

语法:

public boolean equals(Object that)

参数:该方法取两个整理器对象，两者之间进行比较。 返回值:如果两个排序器对象彼此相等，则返回真，否则返回假。 以下是举例说明等于()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
// equals() 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_1
                = new RuleBasedCollator(simple);

            // Creating and initializing
            // Collator Object
            Collator col_2
                = Collator.getInstance(Locale.US);

            // compare both object
            // using equals() method
            boolean i = col_1.equals(col_2);

            // display result
            if (i)
                System.out.println(col_1
                                   + " is equal to "
                                   + col_2);
            else
                System.out.println(col_1
                                   + " is not equal to "
                                   + col_2);
        }

        catch (ClassCastException e) {

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

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

Output: 

java.text.RuleBasedCollator@5eb2e1c2 is not equal to java.text.RuleBasedCollator@289747d6
