Examples of org.jfree.data.time.Quarter

org.jfree.data.time.Quarter
Defines a quarter (in a given year). The range supported is Q1 1900 to Q4 9999. This class is immutable, which is a requirement for all {@link RegularTimePeriod} subclasses.

    /**
     * Serialize an instance, restore it, and check for equality.
     */
    public void testSerialization() {


        Quarter q1 = new Quarter(4, 1999);
        Quarter q2 = null;


        try {
            ByteArrayOutputStream buffer = new ByteArrayOutputStream();
            ObjectOutput out = new ObjectOutputStream(buffer);
            out.writeObject(q1);
