Your correct I think I’m not sure
Answer:
b. size
Explanation:
We can use the size() method of java.util.ArrayList to determine the size of an ArrayList in Java. The size() method of the ArrayList class returns an integer which is equal to the number of elements present in the ArrayList.
Below is an example code to illustrate the use of the size() method of the ArrayList:-
ArrayList<Integer> aList = new ArrayList<Integer>(5);
aList.add(25);
aList.add(2);
aList.add(5);
aList.add(22);
System.out.println("Size of the array list: " + aList.size());
This will print the size of the array list as 4 since we've added four numbers into the array list.

An Object-Oriented code or coding refers to a technique of programming that utilizes the identification of classes of objects that are closely tied to the functions with which they are related.
<h3>What is a Procedural Oriented Code?</h3>
This refers to a kind of programming language that utilizes a step-by-step method so as to break down a task into a set or a collection of factors or variables and routines or sub-routines using a set of instructions that are sequential.
Objects in programming refer to a type of abstract data that has a state and behavior. It is a specific instance of a class.
A class in programming is a templated definition of the techniques and variables of a certain type of object.
<h3>What are some of the principles and structures of coding?</h3>
There are 10 principles of coding. Some of them are:
- Keep it simple
- Separate concerns
- Document your Code etc.
Some of these principles can be used in normal day-to-day activity and even in business. item 1 for instance can be used during communication. Effective communication is more effective when it is kept very simple.
It is to be noted that the code referenced in the question is unavailable hence the general answer.

Answer:
b. the number of items in keyIterator is equal to the number of items invalueIterator
Explanation:
A dictionary in python is an unordered and unindexed data structure. It stores data in key-value pairs, this means that for every key in a dictionary, there must be a value. A keys() method is used to create an iterator of dictionary keys. The items of this iterator can be used in a list comprehension, using the dictionary name and the item key to get the values of the dictionary, creating a list of the dictionary values. The values attribute can also be used for this purpose but cannot be used to get the keys.
