* Program Name : Compare Two Strings

* File Name : 080-Compare-Two-Strings.java

* Class Name : CompareTwoStrings

* Description:

* This program accepts two Strings from the user and compares them

* using equals(), equalsIgnoreCase(), and compareTo() methods.

* Objective:

* - Understand different ways to compare Strings in Java.

* - Learn the use of equals(), equalsIgnoreCase(), and compareTo().

* - Display comparison results.

import java.util.Scanner;

public class CompareTwoStrings {

// The main() method is the entry point of every Java application.

public static void main(String[] args) {

// Create a Scanner object to read input from the keyboard.

Scanner scanner = new Scanner(System.in);

// Ask the user to enter the first string.

System.out.print("Enter the First String: ");

// Read the first string.

String firstString = scanner.nextLine();

// Ask the user to enter the second string.

System.out.print("Enter the Second String: ");

// Read the second string.

String secondString = scanner.nextLine();

// Compare the strings using equals() method.

boolean equalsResult = firstString.equals(secondString);

// Compare the strings using equalsIgnoreCase() method.

boolean ignoreCaseResult = firstString.equalsIgnoreCase(secondString);

// Compare the strings using compareTo() method.

int compareToResult = firstString.compareTo(secondString);

// Display the result of equals().

System.out.println("Using equals(): " + equalsResult);

// Display the result of equalsIgnoreCase().

System.out.println("Using equalsIgnoreCase(): " + ignoreCaseResult);

// Display the result of compareTo().

System.out.println("Using compareTo(): " + compareToResult);

// Explain the compareTo() result.

if (compareToResult == 0) {

// Both strings are equal.

System.out.println("Both Strings are Equal.");

} else if (compareToResult > 0) {

// The first string is greater.

System.out.println("First String is Greater than Second String.");

} else {

// The second string is greater.

System.out.println("First String is Less than Second String.");

}

// Example Output:

// Enter the First String: Java

// Enter the Second String: java

// Using equals(): false

// Using equalsIgnoreCase(): true

// Using compareTo(): -32

// First String is Less than Second String.

// Close the Scanner object to release system resources.

scanner.close();
