Why isn't there operator overloading (CoreJava)

Question :Why isn't there operator overloading? (CoreJava)
Answer :Because C++ has proven by example that operator overloading makes
code almost impossible to maintain. In fact there very nearly wasn't even
method overloading in Java, but it was thought that this was too useful for
some very basic methods like print(). Note that some of the classes like
DataOutputStream have unoverloaded methods like writeInt() and
writeByte().
