Java program to convert a binary number to Decimal [Shortcut Method]

 Java program to convert a binary number to Decimal [Shortcut Method]

I have used basic String functions and explicit type casting to achieve the goal.. Please find the code below:-

import java.util.*;

public class binarytodecimal

{

public static void main(String[] args)

{

    Scanner sc=new Scanner(System.in);

    System.out.println("Enter the binary number");

    int bin=sc.nextInt();

    int sum=0,i,j;

    String bina = Integer.toString(bin);

    int len=bina.length()-1;

    for(i=len,j=0;i>=0&&j<=len;i--,j++)

    {

        sum+=(Character.getNumericValue(bina.charAt(i)))*Math.pow(2,j);

    }

    System.out.println("The decimal number is:"+sum);

}

}
