Java Program to Convert Binary to Octal

This is a Java Program to Convert Binary to Octal.

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 Binary from user. We define a method as convert() to convert the user’s input to Octal.

Here is the source code of the Java Program to Convert Binary to Octal. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

  1. import java.util.Scanner;
  2.  class Binary_Octal
  3.  {
  4.                  Scanner scan;
  5. 	int num;
  6. 	void getVal() 
  7. 	{
  8.                      System.out.println("Binary to Octal");
  9. 	    scan = new Scanner(System.in);
  10.  	    System.out.println("\nEnter the number :");
  11. 	    num = Integer.parseInt(scan.nextLine(), 2);
  12. 	}
  13. 	void convert() 
  14. 	{
  15. 	        String octal = Integer.toOctalString(num);
  16. 	       System.out.println("Octal Value is : " + octal);
  17. 	}
  18.  }
  19. class Main_Class
  20. {
  21.   public static void main(String... d) 
  22.     {
  23.         Binary_Octal obj = new Binary_Octal();
  24.         obj.getVal();
  25.         obj.convert();
  26.    }
  27. }

Output:

$ javac Main_Class.java
$ java Main_Class
 
Binary to Octal
 
Enter the number :
1010
Octal Value is : 12
