单项选择题

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
