In this day and age, you need to be proficient in object-oriented programming like Java. If you face issues, you should seek and clarify your doubts. In the meantime, you should focus on the topics mentioned in this blog.
An abstract class is a type of class that has the abstract keyword in its declaration.
Abstract classes may or may not have abstract methods, that is, methods without a body (public void get(); ).
A class must be designated abstract if it has at least one abstract method.
A class that has been declared abstract cannot be instantiated.
You must inherit an abstract class from another class and supply implementations for the abstract methods in it in order to use it.
A multi-threaded program is made up of multiple components that can operate in parallel.
Each component can tackle a distinct task at the same time while making the best use of the resources available.
The life cycle of a thread consists of new, runnable, waiting, timed waiting, and terminated (dead)
If you are work on a multithreading question and find it to be intricate, do not hesitate in seeking programming homework help.
When a program's usual flow is broken by an Exception, the program/Application terminates unexpectedly.
While studying exceptions, you need to pay attention to unchecked exceptions, checked exceptions and errors.
Exceptions occur when the user enters invalid data, a file cannot be found or if there is a network disruption.
It is an extensive topic, and data structures consist of the following classes and packages.
You should spend time on each of these classes (which have been deemed legacy).
5.Socket Programming (Networking)
TCP sockets provide a means of communication between two machines. At its end of the conversation, a client application builds a socket and attempts to connect it to a server.
The java.net.Socket class represents a socket. The java.net.ServerSocket gives the server application a way to listen for clients and make connections with them.
The accept() function of the Server Socket class is called by the server. This method waits for a client to connect to the server on the specified port before returning.
These are some of the topics that you must analyse thoroughly. If you need , hire professional experts.
