// Decimal to Octal (Built-in)
import java.util.Scanner;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        // Step 1: Prompt user for a decimal number
        System.out.print("Enter a decimal number: ");
        int decimalNumber = scanner.nextInt();

        // Step 2: Use Integer.toOctalString()
        // This method directly converts the decimal integer to its octal string representation.
        String octalString = Integer.toOctalString(decimalNumber);

        // Step 3: Display the result
        System.out.println("Octal equivalent: " + octalString);

        scanner.close();
