Answer 1

class convertBinarytoDecimal{
     public static void main (String args[])
     throws Exception {
          System.out.println("Enter the Binary Number");
          BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
          String str = br.readLine().trim();
          int [] myArray = new int [str.length()];
          for(int i=0;i<myArray.length;i++){
               myArray[i] = Integer.parseInt(str.charAt(i)+"");
          convertBinarytoDecimal(myArray);
     static void convertBinarytoDecimal(int [] myArray){
          int decimal = 0;
          for (int i =0;i<myArray.length;i++){
               decimal += myArray[i] * Math.pow(2,myArray.length-(i+1));
          System.out.println(decimal);
}
