Read the javadoc for java.lang.Character. Your first job is to ensure that all characters are treated as lower case (or upper case)

If I am correct ,each characters of alphabet has unique number in in ASCI.
like A is 65, B is 66 so on. a=97, b=98 and so on.
so when user input a character u can check whether it is capital or simple.
Let's say it is simple then we know it is 97 to 122 range. then we can deduce 96 from the converted chart to decimal.
so you know what the number is now.
as an example if it is b,
b is converterd to decimal then it is 98 and deduce 9896 and u get the answer is 2.
you have to find the suitable methode to convert char to decimal in java. since i am not a java programmer.

Cast 'a' to Integer to get 97
Cast 'A' to Integer to get 65
The following letters obey this order 'a''z' and 'A' to 'Z'
Read input, check if between 97 and 122
Check if between 65 and 90
Subtract accordingly
