How does the object oriented nature of Java enable programmers to more efficiently develop software and make programs?

The object oriented nature of Java allows for the code to be more modular, which enables developers to separate different functional parts of code into distinct parts, which makes code easier to follow. Encapsulation (a core part of object oriented programming) allows for code to be more closely attached to the data is manipulates, which allows for the efficient class and object structures found in Java.

What is a hash map, and what is it used for?

A hash map is a data structure that is designed to store information based on a key, and when that key is used, the data that corresponds to that key is returned. Hash maps make use of hash functions that allow for data to be found in a way that is computationally efficient.

Is C++ a static or dynamically typed language?

C++ is a statically typed language, given that it does type checking at compile time (as opposed to run time)
