/**

 * throw a {@link ClassCastException}.//  w w w  . j  a v a  2s.  c o  m

 * @since 0.1.0
 * @version 0.1.0
 * 
 * @param <T> The type of the casting class
 * @param c The class type to cast to
 * @return A casted value, or {@code null} if unable to cast. If the passed
 *         class parameter is of a primitive type or autoboxed primitive,
 *         then a casted value of -1 is returned, or {@code false} for
 *         booleans. If the passed class parameter is for {@link String},
 *         then {@link Object#toString()} is called on the value instead
