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
            // RuleBasedCollator Object
            RuleBasedCollator col
                = new RuleBasedCollator("< a< b< c< d");

            // 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);
        }
