Java Abstract Data Type in Data Structure – ADT

1. Java ADT – Objective

Previously we saw, Data Structure in Java, and today we will talk about our fourth part Java Abstract Data Type in Data Structure notes, with a list of Abstract Data Types: List ADT, Stack ADT, and Queue ADT in detail, also we will discuss abstract data types problems.

So, let us start Java Abstract Data Types.

2. What is the Java Abstract Data Type (ADT)?

Java abstract data type(ADT) in a data structure is a type of data type whose behaviour is defined by a set of operations and values.

In Java abstract data type, we can only know what operations are to be performed and not how to perform them i.e. it does not tell how algorithms are to be implemented or how the data will be organized in the memory. This type is thus called abstract as it does not give the view of implementation.

The client of data compose require not realize that data write is implemented, for instance, we have been utilizing int, float, and char data type just with the learning with values that can take and tasks that can be performed on them with no thought of how these sorts are executed. So a client just has to comprehend what a data write can do yet not how it will do it. We can consider ADT a discovery which shrouds the inward structure and plan of the data compose. Presently we’ll characterize three Java ADTs to be specific  ADT, Stack ADT, and Queue ADT.

3. List of Abstract Data Types (ADTs)

a. List ADT

List ADT – Java Abstract Data Type, rundown contains elements of the same sort orchestrated in a consecutive request and following activities can be performed on the rundown.

"List

i. get() – Return an element from the rundown at any given position.

ii. insert() – Insert an element in any situation of the rundown.

iii. remove() – Remove the main event of any element from a non-discharge list.

iv. removeAt() – Remove the element at a predefined area from a non-exhaust list.

v. Replace() – Replace an element in any situation by another element.

vi. size() – Return quantity of elements in the rundown.

vii. isEmpty() – Return true if the list is unfilled, generally return false.

viii. isFull() – Return true only if the list is full, generally return false.

b. Stack ADT

A Stack ADT- java Abstract Data Type, contains elements of same sorted in a consecutive request. All tasks happen at a single end that is best of the stack and the following activities can be performed:

Stack ADT- Stack Abstract Data Type

Stack ADT- Stack Abstract Data Type

i. push() – Insert an element toward one side of the stack called a top.

ii. pop() – Remove and restore the element at the highest point of the stack, in the event that it isn’t void.

iii. peep() – Return the element at the highest point of the stack without expelling it, if the stack isn’t void.

iv. estimate() – Return quantity of elements in the stack.

v. isEmpty() – Return genuine if the stack is vacant, generally return false.

vi. isFull() – Return genuine if the stack is full, generally return false.

c. Queue ADT

A Queue ADT – Java Abstract Data Type contains elements of the same sort arranged in successive order. Tasks happen at the two ends, addition is done at the end and erasure is done at front. Following activities can be performed:

Queue ADT - Queue Abstract Data Type

Queue ADT – Queue Abstract Data Type

i. enqueue() – Insert an element toward the finish of the queue.

ii. dequeue() – Remove and restore the primary element of the queue, if the queue isn’t void.

iii. peek() – Return the element of the queue without evacuating it, if the queue isn’t unfilled.

iv. size() – Return quantity of elements in the queue.

v. isEmpty() – Return true if the queue is unfilled, generally returns false.

vi. isFull() – Return true if the queue is full, generally returns false.

So, this was all about Java Abstract Data Types. Hope you like our explanation.

4. Conclusion

Hence, In this Java ADT tutorial, we are learned Java Abstract Data Type (ADT) and the types of Abstract Data Type in Java: List ADT, Stack ADT, and Queue ADT in detail with the end of this tutorial we have covered all types of data structures. In the upcoming tutorials, we will study in detail the different types that we have studied. Furthermore, if you have any query, feel free to ask in a comment section.
