    System.out.println(i);/*w  w w.ja  v a 2 s  . c o m*/
}

From source file:Main.java

    out.printf("equals? = %s, hashCode? = %s %n", (date.equals(other)), (date.hashCode() == other.hashCode()));

    Date todayeOne = trim(date);
    Date todayTwo = trim(other);

    out.printf("equals? = %s, hashCode? = %s %n", (todayeOne.equals(todayTwo)),
            (todayeOne.hashCode() == todayTwo.hashCode()));
