Which code fragments print 1?

The correct answer is A. String arr [] = {"1", "2", "3"}; C. String arr [] = {"1", "2", "3"}. Note:You can replace the type arguments required to invoke the constructor of a generic class with an empty set of type parameters (<>) as long as the compiler can infer the type arguments from the context. This pair of angle brackets is informally called the diamond.
