Octal to Binary Conversion in Java for Beginners

Welcome to the intriguing world of programming, where numbers play just as essential a role as creativity! In this blog, we’re diving into the fascinating yet simple journey of Octal to Binary Conversion in Java. If you’ve just started your coding adventure, then this concept will be an exciting addition to your knowledge arsenal. Converting octal numbers to binary is not as complicated as it sounds. This guide will walk you through every step in plain, friendly language. So, ready to unlock more coding mysteries? Let’s dive in and make this topic as easy as your morning chai!

Code Example for Octal to Binary Conversion in Java

import java.util.Scanner;

public class OctalToBinary {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter an octal number: ");
        String octalInput = scanner.nextLine();

        int decimal = Integer.parseInt(octalInput, 8);
        String binary = Integer.toBinaryString(decimal);

        System.out.println("Binary equivalent: " + binary);
    }
}
  

Explanation of the Code

1. The program starts by importing the Scanner class. This is essential because it allows us to read user’s input. So, yeah, it’s the part where your interaction begins!
2. Next, the code creates a class named `OctalToBinary`. In Java, classes are like blueprints, containing everything about the program.
3. The `main` method kicks off the program. Here, input from the user is accepted as an octal number.
4. Now, the magic happens when we use `Integer.parseInt(octalInput, 8)`. This converts the octal number to decimal. Cool, right?
5. Finally, `Integer.toBinaryString(decimal)` is used to convert the decimal result into a binary string, which gets printed. By following these simple steps, you’ve just performed an Octal to Binary Conversion in Java!

Output

Enter an octal number: 
Binary equivalent: 1001001
