Example: StringComparison in Java

// StringComparison
public class Main {
    public static void main(String[] args) {
        // Step 1: Initialize strings for comparison
        String str1 = "hello";
        String str2 = "hello";
        String str3 = "world";
        String str4 = "Hello"; // Different case

        // Step 2: Compare using equals() method (case-sensitive)
        boolean isEqual1 = str1.equals(str2); // true
        boolean isEqual2 = str1.equals(str3); // false
        boolean isEqual3 = str1.equals(str4); // false (case-sensitive)

        // Step 3: Compare using equalsIgnoreCase() method (case-insensitive)
        boolean isEqualCaseInsensitive = str1.equalsIgnoreCase(str4); // true

        // Step 4: Demonstrate incorrect comparison using == (compares object references)
        String newStr1 = new String("test");
        String newStr2 = new String("test");
        boolean isEqualReference = (newStr1 == newStr2); // false, as they are different objects

        // Step 5: Print comparison results
        System.out.println("str1 (\"" + str1 + "\") equals str2 (\"" + str2 + "\"): " + isEqual1);
        System.out.println("str1 (\"" + str1 + "\") equals str3 (\"" + str3 + "\"): " + isEqual2);
        System.out.println("str1 (\"" + str1 + "\") equals str4 (\"" + str4 + "\"): " + isEqual3);
        System.out.println("str1 (\"" + str1 + "\") equalsIgnoreCase str4 (\"" + str4 + "\"): " + isEqualCaseInsensitive);
        System.out.println("newStr1 (\"" + newStr1 + "\") == newStr2 (\"" + newStr2 + "\"): " + isEqualReference + " (Incorrect for content comparison)");
    }
