You want to use te Coherence Java APIs to directly cached POJOs. Consider this snippet of code: NamedCache cache - CacheFactory.getCache("mycache");  cache.put(new Integer(I)f "hello"); cache.put(T,"hi");  cache.put(new Long(II),"hey");  This code inserts three objects into the cache.  Why ?()
A: hashCode() and equals() method for each object type is different so a different key is used
B: each object value string is different so a different value is inserted on each put
C: equals() and compare() method is different for each put
D: POF need to be implemented for this to work properly
