Java 中的排序器等于(字符串，字符串)方法，示例

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

java.text.Collator 类的 equals() 方法用于检查两个字符串是否相同。

语法:

public boolean equals(String source,
                      String target)

参数:该方法取两个字符串，在这两个字符串之间进行比较。

返回值:如果两个字符串相等，则返回真否则返回假。

以下是说明等于()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
// equals() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {

            // Creating and initializing
            // Collator Object
            Collator col = Collator.getInstance();

            // Creating an initializing
            // object for comparison
            String obj1 = "a";

            // Creating an initializing
            // Object for comparison
            String obj2 = "A";

            // compare both object
            // using equals() method
            boolean i = col.equals(obj1, obj2);

            // display result
            if (i)
                System.out.println(obj1
                                   + " is equal to "
                                   + obj2);
            else
                System.out.println(obj1
                                   + " is not equal to "
                                   + obj2);
        }

        catch (ClassCastException e) {

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

Output: 

a is not equal to A

例 2:

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
            // Collator Object
            Collator col = Collator.getInstance();

            // Creating an initializing
            // object for comparison
            String obj1 = "a";

            // Creating an initializing
            // Object for comparison
            String obj2 = "a";

            // compare both object
            // using equals() method
            boolean i = col.equals(obj1, obj2);

            // display result
            if (i)
                System.out.println(obj1
                                   + " is equal to "
                                   + obj2);
            else
                System.out.println(obj1
                                   + " is not equal to "
                                   + obj2);
        }

        catch (ClassCastException e) {

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

Output: 

a is equal to a
