Ejemplo 1: Java convierte binario a decimal

import java.util.Scanner;
public class BinaryToDecimalDemo 
{
   public static void main(String[] args) 
   {
      int number, decimal = 0, a = 0;
      Scanner sc = new Scanner(System.in);
      System.out.println("Please enter binary number: ");
      String strBinary = sc.nextLine();
      number = Integer.parseInt(strBinary);
      while(number != 0){
         decimal += (number % 10) * Math.pow(2, a);
         number = number / 10;
         a++;
      }
      System.out.println("Decimal number: " + decimal);
      sc.close();
   }
}

Ejemplo 2: binario a decimal en un programa java

public class Details {
 
  public int BinaryToDecimal(int binaryNumber){
 
    int decimal = 0;
    int p = 0;
    while(true){
      if(binaryNumber == 0){
        break;
      } else {
          int temp = binaryNumber%10;
          decimal += temp*Math.pow(2, p);
          binaryNumber = binaryNumber/10;
          p++;
       }
    }
    return decimal;
  }
 
  public static void main(String args[]){
    Details obj = new Details();
    System.out.println("110 --> "+obj.BinaryToDecimal(110));
    System.out.println("1101 --> "+obj.BinaryToDecimal(1101));
    System.out.println("100 --> "+obj.BinaryToDecimal(100));
    System.out.println("110111 --> "+obj.BinaryToDecimal(110111));
  }
}
