Java code for string comparison using Collator and String classes

// importing Collator and Locale classes
import java.text.Collator;
import java.util.Locale;

public class Main {
    //function to print strings (comparing & printing)
    public static void printString(int diff, String str1, String str2) {
        if (diff < 0) {
            System.out.println(str1 + " comes before " + str2);
        } else if (diff > 0) {
            System.out.println(str1 + " comes after " + str2);
        } else {
            System.out.println(str1 + " and " + str2 + " are the same strings.");
        }
    }

    public static void main(String[] args) {
        // Creating a Locale object for US english 
        Locale USL = new Locale("en", "US");

        // Getting collator instance for USL (Locale) 
        Collator col = Collator.getInstance(USL);
        String str1 = "Apple";
        String str2 = "Banana";

        // comparing strings and getting the difference
        int diff = col.compare(str1, str2);

        System.out.print("Comparing strings (using Collator class): ");
        printString(diff, str1, str2);

        System.out.print("Comparing strings (using String class): ");
        diff = str1.compareTo(str2);
        printString(diff, str1, str2);
    }
}

Output

Comparing strings (using Collator class): Apple comes before Banana
Comparing strings (using String class): Apple comes before Banana
