You could do this by comparing the inputed characters. After you ask for an input you will need to check what type of character was inputed with if statements, such as

if(inputChar >= 65 && inputChar <= 90) //65 = 'A' and 90 = 'Z'

	upperCase++;	//An instance variable to store how many upperCase letters

else if(inputChar >= 97 && inputChar <= 122) //97 = 'a' and 122 = 'z'

	lowerCase++;

else if(inputChar >= 48 && inputChar <= 57) // 48 = '0' and 57 = '9'

	numDigits++;

else

	otherLetters++;

There's an easier way. Just use:

int type = Character.getType(c); // where c is a character to test

The result will be in the form of an integer which corresponds with several static integer members of the Character class, for example:

Character.LOWERCASE_LETTER

Character.UPPERCASE_LETTER

Character.MATH_SYMBOL

Character.DECIMAL_DIGIT_NUMBER

Character.START_PUNCTUATION

Character.END_PUNCTUATION

...

The list goes on and on. Just compare the result of the getType() function with these static members in a switch clause and you'll be good to go.

Google the Java documentation on Character.getType() for all the possible character categories.
