Convert Decimal to Octal
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[] args) throws 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);
}
}
