Examples of org.jfree.data.time.Week

org.jfree.data.time.Week
A calendar week. All years are considered to have 53 weeks, numbered from 1 to 53, although in many cases the 53rd week is empty. Most of the time, the 1st week of the year *begins* in the previous calendar year, but it always finishes in the current year (this behaviour matches the workings of the GregorianCalendar class).
This class is immutable, which is a requirement for all {@link RegularTimePeriod} subclasses.

    
    /**
     * Two objects that are equal are required to return the same hashCode. 
     */
    public void testHashcode() {
        Week w1 = new Week(2, 2003);
        Week w2 = new Week(2, 2003);
        assertTrue(w1.equals(w2));
        int h1 = w1.hashCode();
        int h2 = w2.hashCode();
        assertEquals(h1, h2);
    }
