In this section, you will learn to convert decimal number into octal. 

The decimal format has 10 digits (that are 0,1,2,3,4,5,6,7,8,9) with base  10. The octal number has 8 digits (as: 0,1,2,3,4,5,6,7) with base 8.

Description of code:

This program takes a decimal number at console and converts it into a  octal number  using the toString() method. The given number is taken in string format so, it must be converted into an integer type data . The toString() method converts decimal number  into the octal number.

Integer.toString(value, 8):
This method returns a string object to represent a  specified integer. It converts the decimal number into octal. This method takes two parameters: value and 8.  And it converts the signed decimal representation into the octal format. It returns back the number as a  string.

Here is the code of this program:

import java.io.*;
import java.lang.*;

public class DecimalToOctal {
  public static void main(String[] argsthrows IOException{
  BufferedReader buff = new BufferedReader(new InputStreamReader(System.in));
  System.out.println("Enter the decimal number:");
  String deci = buff.readLine();
  int value = Integer.parseInt(deci);
  String str = Integer.toString(value,8);
  System.out.println("octal:=" + str);
  }
}
