	public static void main(String[] args) {
		char firstValue = 'A';
		char secondValue = 'B';
		// compare the first char to the second
    	int result = Character.compare(firstValue, secondValue);
    	if (result == 0) {
      		System.out.println("The chars are the same.");
    	} else {
          	System.out.println("The chars are different.");
