Constructs a ClassCastException with the specified detail message.

Usage

From source file:Main.java

/**
 * This constructs an <code>Iterator</code> over each day in a date
 * range defined by a focus date and range style.
 *
 * For instance, passing Thursday, July 4, 2002 and a
 * <code>RANGE_MONTH_SUNDAY</code> will return an <code>Iterator</code>
 * that starts with Sunday, June 30, 2002 and ends with Saturday, August 3,
 * 2002, returning a Calendar instance for each intermediate day.
 *
 * @param focus  the date to work with, either
 *  <code>Date</code> or <code>Calendar</code>
 * @param rangeStyle  the style constant to use. Must be one of the range
 * styles listed for the {@link #iterator(Calendar, int)} method.
 * @return the date iterator/*from   ww w  . java 2  s  .c o m*/
 * @throws IllegalArgumentException if the date
 *  is <code>null</code>
 * @throws ClassCastException if the object type is
 *  not a <code>Date</code> or <code>Calendar</code>
