public class Solution {

    private static String UNEXPECTED_TYPE = "I didn't expect this type of number!";

    public static void main(String[] args) {
        System.out.println(toCustomString((byte) 12));
        System.out.println(toCustomString(12));

       if (number instanceof Byte) {
       newByte = (byte) (number / 2);
       String finalByte = newByte.toString() + "b" ;
       return finalByte; }

       else if (number instanceof Integer) {
       newInt = (int) number / 3 ;
       String finalInt = Integer.toString(newInt);
       return finalInt; }

       else if (number instanceof Double) {
       newDouble = (double) number / 20;
       String finalDouble = newDouble.toString();
       return finalDouble; }

       else return finalCondition;

Implement the toCustomString method so that it converts a Number to a String according to a specific type-dependent rule:

if the argument is a Byte object, then divide it by 2 and convert it to a string, adding the letter "b" at the end;
if the argument is an Integer object, then divide it by 3 and convert it to a string;
if the argument is a Double object, then multiply it by 20 and convert it to a string;
if the argument is not one of the above types, then return the string "I didn't expect this type of number!"

The Number class is the parent of the Byte, Double, Float, Integer, Long, and Short classes.
Use the instanceof operator to determine the type.

Requirements:

The toCustomString method must divide the input parameter by 2 and add the letter b at the end, if the input parameter is a Byte object.
The toCustomString method must divide the input parameter by 3 if the input parameter is an Integer object.
The toCustomString method must multiply the input parameter by 20 if the input parameter is a Double object.
The toCustomString method should return the string "I didn't expect this type of number!", if the input parameter is not a Byte, Integer, or Double.
To determine the type, you need to use the instanceof operator.
