A look into various data structure and algorithms in JAVA
from web site
Knowing the types of data structure and algorithms in JAVA and in other programming languages is useful for programmers. Using the Best data structure and algorithms online course is not only necessary for program design and efficiency but also facilitates understanding.
Fortunately, Java supports a wide range of data structures, from basic to more advance.
Array
Arrays are more or less building blocks of JAVA data structures. An array usually contains a certain number of elements in a list defined as:
Int [] Array = new int [4];
Arrays can contain objects of any kind, but all must be of the same type.
ArrayList
ArrayList extends arrays by making its size dynamic. You can store different types of objects in the same ArrayList menu.
List
The Java list data structure is actually an ArrayList list, with the difference that only one type of object can be stored. This is an advantage in terms of software speed and readability.
Linked List
LinkedList is a more advanced data structure. This structure consists of a "node" with three values. The object to be saved, a reference to the previous node, and a reference to the next node. Most describe it as a chain, every connection to the rest of the list.
Dictionary
The dictionary structure is similar to the menu structure but is indexable. That is, instead of auto-generated alternatives (0,1,2,3 ... etc.), they are of any type defined by the user.
The Hash set
HashSet has been a new feature of Java.
Stacks and queues
The stack and queue data structures are very similar. Both are list shapes that return only one object at a particular location. Queues return objects in the way they are added. The stack, on the other hand, returns the last object added.
