Use java.lang.Character class methods.

public boolean isDigit(char c) { 
  return ((c >= '0') && (c <= '9'));
}

public boolean  isAlphabet(char c) {
  return ( (c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z') );
}

Respectively:

java.lang.Character.isLetter(c);
java.lang.Character.isDigit(c);

But if you want to make your own implementations:

boolean isAlpa(char c) {
    return c >= 'A' && c <= 'Z'; /* single characters are
            enclosed with single quotes */
}
