package com.bethecoder.tutorials.guava.base_tests;

import com.google.common.base.CharMatcher;

public class CharMatcherIsNotTest {

  /**
   @param args
   */
  public static void main(String[] args) {
    System.out.println(CharMatcher.is('A').matches('A'));
    System.out.println(CharMatcher.is('A').matches('a'));
    
    System.out.println(CharMatcher.isNot('A').matches('a'));
    System.out.println(CharMatcher.isNot('A').matches('9'));
    System.out.println(CharMatcher.isNot('A').matches('#'));
    System.out.println(CharMatcher.isNot('A').matches('A'));
  }
