Example: String Reversal using toCharArray() and StringBuilder in Java

// String Reversal using toCharArray() and StringBuilder
public class Main {
    public static void main(String[] args) {
        String originalString = "development";
        
        // Step 1: Convert the string to a character array
        char[] charArray = originalString.toCharArray();
        
        // Step 2: Use StringBuilder for efficient appending
        StringBuilder reversedBuilder = new StringBuilder();

        // Step 3: Iterate through the char array from end to beginning
        for (int i = charArray.length - 1; i >= 0; i--) {
            // Step 4: Append each character to the StringBuilder
            reversedBuilder.append(charArray[i]);
        }
        
        // Step 5: Convert StringBuilder back to a String
        String reversedString = reversedBuilder.toString();

        System.out.println("Original String: " + originalString);
        System.out.println("Reversed String: " + reversedString);
    }
