This Tutorial helps you to know the code for Java binary to a decimal number.

In this Tutorial we want to describe you a code that help you in understanding a how to get a 'Java binary to decimal'. For this we have a class BinarytoDecimal, Inside this class we have a main method that includes-

1)Buffered Reader   -  This is used to read a character stream from a file present in input stream reader.

The System.out .print  print  the binary specified  inside the braces.

2)readline ( )   - This is used to read the binary value entered by the user and store the value in a string variable s.

3)Integer.Parse ( )  -The integer class has a method parseInt( ) that returns you the integer value from  string passed as argument representation. 

Finally the System.out.println print the decimal value from the binary value. 

BinarytoDecimal.java

import java.io.BufferedReader;
import java.io.InputStreamReader;
public class BinarytoDecimal {

    public static void main(String[] args) throws Exception {
       BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter the binary value:");
         String s = br.readLine();
        System.out.println("Decimal value is : "+Integer.parseInt(s, 2));

    }
}

Output of the program

  Enter the binary value:
110111
Decimal value is : 55
