- In JSON, anything that is surrounded by curly braces { } is considered Select one: a. Attribute b. Array c. Value d. ObjectWhen working with enumeration types, such as the arithmetic operators and the stream operators, is it possible to rapidly access operators that are often used, such as the arithmetic operators and the stream operators? Is it conceivable, for instance, to overload these operators in order to arrive at a result that is satisfactory? What are the arguments for and against doing so?Pointer variables are just that. Why? What is "dynamic array"? What's their relationship?

- My homework was to design and implement a simple social network program in Java. I should use an adjacency matrix data structure in my implementation. Write a social network program in Java. The default information for this network is stored in two files: index.txt and friend.txt. The file index.txt stores the names of the people in the network – you may assume that we only store the given names and these names are unique; and friend.txt stores who knows whom. The program must read these two files. The following section describes the format of these two files. The friend.txt takes the following format. The first line is the number of pairs of friends. Each subsequent line has two integer numbers. The first two numbers are the indices of the names. The following is an example of friend.txt:50 31 30 12 41 5 The index.txt stores the names of the people in the network. The first line is the number of people in the file; for example:60 Gromit1 Gwendolyn2 Le-Spiderman3 Wallace4 Batman5…A Java collection is any class that implements the Collection interface. O True FalseSets and Maps A map is a container object that stores a collection of key/value pairs. It enables fast retrieval, deletion, and updating of the pair through the key. A map stores the values along with the keys. The keys are like indexes. In List, the indexes are integers. In Map, the keys can be any objects. A map cannot contain duplicate keys. Each key maps to one value. A key and its corresponding value form an entry stored in a map. There are three types of maps: HashMap, LinkedHashMap, and TreeMap. The common features of these maps are defined in the Map interface. 1.1 Using the Map interface knowledge, create a Java application in NetBeans that implements a HashMap and a LinkedHashMap. The application must do the following: a. Add at least 5 elements to the HashMap b. Print out all the elements in the HashMap including their keys c. Find and print out the value of a specific index d. Remove one of the elements from the HashMap e. Print out the HashMap after removing the element f.…
