Example: Get String Length using charAt() and try-catch in Java

// Get String Length using charAt() and try-catch
    import java.util.Scanner;

    // Main class containing the entry point of the program
    public class Main {
        public static void main(String[] args) {
            // Step 1: Initialize a string and a counter
            String str = "Hello Java";
            int lengthCounter = 0;

            // Step 2: Use a try-catch block to iterate and detect end
            try {
                while (true) {
                    str.charAt(lengthCounter); // Attempt to access character
                    lengthCounter++; // Increment counter if successful
                }
            } catch (StringIndexOutOfBoundsException e) {
                // Step 3: The exception is caught when lengthCounter exceeds string bounds
                // The value of lengthCounter at this point is the string's length
                System.out.println("String: \"" + str + "\"");
                System.out.println("Length (using charAt and try-catch): " + lengthCounter);
            }
        }
    }
