I have to deal with character comparisons using the ASCII table
Read in a single keyboard character and display an appropriate message depending on whether it was a letter, a digit or some other type of character. Use a nested else-if statement
Could someone please give a solution for this problem
Thanks
Sean.

That is quite easy using the java.lang.Character class. It has plenty of useful methods to identify characters kinds, for instance:

static boolean isLetter(char ch)
static boolean isDigit(char ch)

among others.

These methods are static so don't try to instantiate a new Character class in order to use them

Regards.
