Let's say you want a method which will determine if the given character is a vowel, consonant, or other (non-letter). // Will return a String representation of what the given character is: // "vowel" "consonant" or "other" public static final String getTypeOfChar(final char c) { // since chars are an integer data type in Java, we can switch on them switch(c) { case 'a': // all of these cases "fall through" to the next non-case statement case 'e': // if any of them matches case 'i': case 'o': case 'u': return "vowel"; case 'b': // again, all of these cases fall through case 'c': case 'd': case 'f': case 'g': case 'h': case 'j': case 'k': case 'l': case 'm': case 'n': case 'p': case 'q': case 'r': case 's': case 't': case 'v': case 'w': case 'x': case 'y': case 'z': return "consonant"; default: // if we have no matches yet, do this return "other"; } }
