- in java, Two abstract data types are the ordered list and the unordered list. Explain how these two ADTs are similar and how they differ. To answer this question, assume that you do not know how they are implemented (that is, whether they are implemented using an array or a linked list).Please give a detailed answer and code examples for all of the questions below.What is an array and linked list?What the difference between array and List?Difference between ArrayList and Arrays in Java?Please answer in Java, thank you. The purpose of this assignment is to practice your knowledge of how a linked data structure is implemented. This is a more advanced version of a linked list, and will help to give you practice in how to deal with data structures connected through references. This assignment is very important to help you understand the fundamentals of Linked Lists. At the end of this assignment, you should be able to fully understand how any variation of a Linked List is implemented. Instructions: For this project you will be implementing a new data structure called LinkedGrid. This is a linked type data structure version of a 2D array. The LinkedGrid can support any combination of dimensions (n x n, n x m, or m x n, where n > m) This data structure has a singly linked system which allows you to traverse the grid in multiple directions in addition to allowing you to retrieve specific rows and columns. The following diagram gives a rough visual of this data…
- writing a general-purpose sort method in Java, the sort method needs to compareobjects. There are two ways to give the sort method the code to compare objects,implementing the interfaces Comparable and Comparator respectively. Briefly, describe thetwo ways. Write excerpts of use examplesThe implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.In JAVA, explain about Map and its types.
- Explain the use of generics in conjunction with the Comparable interface in Java. How does it enhance type safety when sorting collections?In writing a general-purpose sort method in Java, the sort method needs to compareobjects.

- What is the java “meta” type enum? Group of answer choices 1. Where other languages, like Python and C, use arrays, Java instead uses enum. 2. It is a way to represent books. 3. It is a way to iterate through a list. 4. A set of categorical names for which all possible values are known in advance.Using java language In voltTest[10] is an encapsulated array that contains 10 voltages. Display how many are ACTIVE (5V), SATURATED (greater than 5V) and CUTOFF (less than 5V). Use the UML diagram as a reference. setValue(int,int,int) – accepts the value of voltActive, voltSaturated and voltCutoff as a parameter, which is the number of active, saturated and cutoff voltages. displayResult() – displays the number of active, saturated and cutoff voltages.Write a Java program using OOP concept that perform the union and symmetric difference between two sets. Use class, object and method in code. A = { a, b, c, e, f }B = { d, e, f, g }
