We make a class with two methods one for input and other for conversion and access this by object of this class. We first take the input as Octal from user. We define a method as convert() to convert the user’s input to Binary.
Here is the source code of the Java Program to Convert Octal to Binary. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.
System.out.println("Octal to Binary");
scan = new Scanner(System.in);
System.out.println("\nEnter the number :");
num = Integer.parseInt(scan.nextLine(), 8);
String binary = Integer.toBinaryString(num);
System.out.println("Binary Value is : " + binary);
public static void main(String args)
Octal_Binary obj = new Octal_Binary();
$ javac MainClass.java $ java MainClass Octal to Binary Enter the number : 10 Binary Value is : 1000
