A double is just like a float but with higher precision. Its certainly not a String or (char)acter and so cant hold the character you entered, so you have to use a different datatype there.

so at the last line i have to change it to
Char ch = input.nextChar();

Still i need to figure out how to replace 2nd and 4th in num and replace it with integer d.
As well display the precedent and the letter that comes after ch before&after the number.
