Convert Octal to Decimal

In this section, you will learn to convert an octal number to decimal. The following program helps you converts number octal to decimal.

Description of code:

This program takes an octal number at console converts it into decimal number using parseInt() method. This method parses the string value as a signed integer in the radix specified by the second argument as 8. And you get the decimal number.

Integer.parseInt(oct, 8): This method takes an int value in a string format and it returns an Integer object. It converts an octal number into decimal and takes two parameters. First argument passed is a specified String which is parsed using the radix given through the second argument. The first parameter interprets as representing a signed integer in the radix specified by the second parameter.

Use Keyboard as :S- This is a string to be parsed.
Radix (as a use integer value):- The radix represents an integer value to be parsed in the interpreting string.

Here is the code of this program:


import java.io.*;

import java.lang.*;



public class  OctalToDecimal{

  public static void main(String[] args)throws IOException{

    BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

    System.out.println("Enter the octal number:");

    String oct = reader.readLine();

    int i= Integer.parseInt(oct,8);

    System.out.println("Decimal:=" + i);

  }

}

C:\corejava>java OctalToDecimal
