NEW QUESTION # 65
Which of the following can fill in the blank in this code to make it compile?

A. default
B. final
C. int
D. private
E. abstract

Answer: D

Explanation:
From Java SE 8, we can use static and/or default methods in interfaces, but they should be non abstract methods. SO in this case using default in blank is completely legal. Hence option C is correct. Option A is incorrect as given method is not abstract, so can't use abstract there. Options B and E are incorrect as we can't have non abstract method interface if they are not default or static. httpsy/docs.oracle.com/javase/tutorial/iava/landl/defaultmethods.html

NEW QUESTION # 71
Identify two benefits of using ArrayList over array in software development.

A. is multi.thread safe
B. implements the Collection API
C. reduces memory footprint
D. dynamically resizes based on the number of elements in the list

Answer: C,D

Explanation:
ArrayList supports dynamic arrays that can grow as needed. In Java, standard arrays are of a fixed length. After arrays are created, they cannot grow or shrink, which means that you must know in advance how many elements an array will hold. But, sometimes, you may not know until run time precisely how large of an array you need. To handle this situation, the collections framework defines ArrayList. In essence, an ArrayList is a variable-length array of object references. That is, an ArrayList can dynamically increase or decrease in size. Array lists are created with an initial size. When this size is exceeded, the collection is automatically enlarged. When objects are removed, the array may be shrunk.
