This code example shows a few of the methods of the Character class. First a variable c is declared which is a variable of type "char" and it is assigned the value "a".
The methods isLowerCase, isUpperCase and isLetter which all returns a boolean value are used to check whether the variable is uppercase, lowercase or if it's a letter.
Finally the results are displayed using System.out.println statements.

package com.javadb.examples;

public class CharacterDemo {
   public static void main(String args[]) {
     char c = 'a';
     boolean lowerCase = Character.isLowerCase(c);
     boolean upperCase = Character.isUpperCase(c);
     boolean letterOrDigit = Character.isLetter(c);
     System.out.println("Is c lowercase? " + lowerCase);
     System.out.println("Is c uppercase? " + upperCase);
     System.out.println("Is c a letter? " + letterOrDigit);
