This article is a convenient, fast reference guide for resources and details on the Top Five Java Concepts All Programmers Must Master. No need to be programming code in this article lets you concentrate on Java fundamentals. Enroll Java Course in Chennai at FITA Academy to learn more about the various Concepts of data. This blog post will review how to comprehend Java's primitive and non-primitive data types. This is because it is advised that you comprehend these ideas before starting to code in Java.

Top Five Java Concepts

Interfaces

Instead of programming to an implementation, you will program to an interface in Java. Programming to interfaces, another term for this technique of writing classes based on an interface specifying an object's behaviour, is another name. Because you have to begin with these three phases, this design approach may appear like it will take more work at first:

Make an interface.
Describe its procedures.
Write the implementation in the class.

Using Java for execution

Process and thread are the two fundamental units of execution in Java. In Java, a process and a thread are defined as follows:

Process: An executable environment that operates independently and can be an application or a program. It can be viewed as a program that has several processes inside of it. A single process is used to operate a Java runtime environment. Additionally, there are many programs and classes within the process itself.

Thread: Is present during the procedure. Shares the process resources and requires fewer resources to develop. Similarly, a thread is a lightweight procedure.

Object-Oriented Programming (OOP)

Object-oriented programming, or OOP, is one of the key ideas in Java. Being an OOP language, Java places a greater emphasis on data than on functions. The focus of OOP programming languages is on objects. Enrolling in Java Online Course will give you the skills and information needed to excel in OOP.

Changeable

Variables are Java storage units used to hold data values. Java supports the following three variable types:

Static or class variables: These don't require an object to be accessed.

Non-static or instance variables: A class object can access these member variables.

Local variables: These only exist within a particular code block and vanish when the block is closed.

Types of Data

Due to Java's strict typing, each piece of data and information has a unique Data Type. Any variable that stores a value must store a character, string, or number. Java stores various types of information using Data Types. Once you specify a data type in Java, it cannot be altered.
