Question

public class Client public static void main(String[] args) //create an object a representing 111001 in binary //display object a //display the decimal value of object a //display base-6 value of object a //create object b with parameter ""1a.23069" //in base 8 and challenging set to false //display object b I/display decimal value of object b //create object d in base-7 holding decimal value 255 //display object d //display the comparison of d with b //display the comparison of a with b //IMPORTANT!!! use print for the last output,NOT pritn

Explanation / Answer

Client .java

public class Client {

   public static void main(String[] args) {
       // String Object a in Binary
       String a = "111001";
       // String Object b in Base 8
       String b = "10.23069";
       String d = "555";
       // Print a
       System.out.println("Binary Value of a is = " + a);
       // get Decimal using Standard method
       System.out.println("Decimal Value of a = " + getDecimal(a, 2));

// get Base 6 using Standard method
System.out.println("Base 6 Value of a = " + getDecimal(a, 6));

// Print b
System.out.println("Value of b is = " + b);

System.out.println("Decimal Value of b = " + getDecimal(b, 8));

       // Print c
       System.out.println("Value of d is = " + d);
       System.out.println("Decimal Value of d = " + getDecimal(d, 7));

System.out.println("Comparison of b and d");

       if (compare(d, b) > 0) {
           System.out.print("D is gretaer than B");
       } else {
           System.out.print("B is gretaer than D");
       }
       // In same way a and b can be compare
   }

   // This method will convert from Base to Decimal
   public static double getDecimal(String value, int base) {
       if (value.contains(".")) {
           String[] arr = value.split("\."); // split fraction part
           return integerPart(arr[0], base) + fractionalPart(arr[1], base);
       } else {
           return integerPart(value, base);
       }
   }

   // conversion of integer part to some other base
   public static double integerPart(String value, int base) {
       double sum = 0;
       int l = value.length();
       for (int i = 0; i < value.length(); i++) {
           int num = Integer.parseInt(String.valueOf(value.charAt(l - 1)));
           sum += num * Math.pow(base, i);
           l--;
       }
       return sum;
   }

   // conversion of decimal part to some other base
   public static double fractionalPart(String value, int base) {
       double sum = 0;
       for (int i = 0; i < value.length(); i++) {
           int power = -i - 1;
           int num = Integer.parseInt(String.valueOf(value.charAt(i)));
           sum += num * Math.pow(base, power);
       }
       return sum;
   }

   // compare d with b
   public static int compare(String d, String b) {
       return (int) (getDecimal(d, 7) - getDecimal(b, 8));
   }

}

Output:

Binary Value of a is = 111001
Decimal Value of a = 57.0
Base 6 Value of a = 9289.0
Value of b is = 10.23069
Decimal Value of b = 8.298614501953125
Value of d is = 555
Decimal Value of d = 285.0
Comparison of b and d
D is gretaer than B
