Binary to Decimal and Decimal to Binary Conversions in Java

Write program that does binary to decimal and decimal to binary conversions.

Program:

package bi_de;

import java.util.Scanner;
public class Bi_De {
    public static void main(String[] args) {
        Scanner sc=new Scanner(System.in);
        System.out.print("Enter Binary number=");
        int d=sc.nextInt();
        System.out.print("Number is Convert into decimal: ");
        decimal(d);
        System.out.println();
        System.out.println();
        System.out.print("Enter Decimal number=");
        int b=sc.nextInt();
        System.out.print("Number is Convert into binary:");
        binary(b);
        System.out.println("\n");
  }

  static void binary(int b){
     if(b>0)
binary(b/2);
System.out.print(b%2);
   }
 
   static void decimal(int d){
int num=0;
double sum=0,rem;
while(d!=0)
{
rem=d%10;
d=d/10;
sum=sum+rem*(Math.pow(2,num));
num++;
}
System.out.print(sum);
    }
}
