In this world of python and JavaScript to learn Java as a programming language for future for training purposes and software development we will be looking at some prospects that suggest you to learn  Java and it's relevant frameworks in 2021.
## Legacy projects
Java is in the software market or in this Software engineering world for almost two two decades many enterprise-level projects including Google Docs Google Drive and Many Google related projects have been built using the Java programming language. The reason behind this is that Java is a very strong object-oriented programming language that allows re-usability of code in a perfect manner ability does not mean that you're copying or pasting code from One file to another but it means that the usability of the same code for different purposes has been increased significantly. Java provides flexibility in order to maintain the security of the project, especially enterprise-level projects. These Legacy projects constantly have to be maintained. Now we have to look at what is meant by moment and ability. maintainability means that keeping the code up-to-date and constantly adding new features to the existing code if no one is learning Java Soho these projects will be updated and how we will experience new feature new features of this excellent project and products. So here comes a very strong reason why you actually learn  in 2021.  Learning Java in 2021 will allow you to work in these Legacy projects efficiently and very easily because the object-oriented approach will allow you to understand code very easily.

## Save you from frequently updating third party libraries
The most common problem with JavaScript frameworks projects is Dad you have to constantly update third-party libraries because after sometime these libraries get deprecated so it is quite possible that due to deprecated libraries your project will not function as it should function. So it becomes a very hectic to update most of the third party libraries from time to time. this problem can easily be avoided by using a legacy programming language such as Java. As most releases of third-party APIs Java Libraries very stable. versions which get updated after two or three years mostly. This allows you to work more on features then updating library. This saves both time and Manpower and this all introduces many new functionalities in the existing Project.
## Heavily secured Project
If you are looking to build an enterprise level software which contains very sensitive information related to customers employees and business, then you should not worry about the programming language and what kind of bugs and bounties are present in the programming language. As JavaScript is becoming common day by day, the hackers and bounty hunter are finding new ways to break JavaScript related websites because website build on Reactjs VUE.JS and Angular.JS are becoming common day by day. So it is very easy to implement security related Aspects in the Java programming language. Java programming language provides painting by SQL injection avoidance system. By the means of special  and built-in  curious by using parameterised queries. This will allow you to build highly secure projects without using or wearing any third party libraries. you will Focus more on customer needs or user needs rather than spending time on securing the data or securing the different functionality of Project.
## Stable Web-Development Frameworks
Most famous Java web frameworks or spring MVC, Spring Boot,  and Thymleaf.  These frameworks come with many building functionalities that saves a lot of time finding third-party libraries regarding very basic tasks. These functionalities include the ability to build RestfulAPIs. RestfulAPIs endpoints are very easy in the Spring boot framework. Spring framework also comes with a spring data fragment that allows object relational mapping of project to database very easy and less time taking. This object relational mapping reduces the effort to write to insert or extract data from database systems. spring boot also comes with the spring security module as well in order to maintain the security and vulnerability of Project. Getting started with a Spring boot project is very easy. You simply have to go to a website in order to get your Maven file,  once you have got your navel file open that file in your IDE for example Intellij IDEA.  all libraries will be downloaded and you will be ready to get started building your next big project.
## User Centric code 
In the Java programming language you can easily implement user-centric code. Now what User-Centric code really means? It simply means that you are writing code may keep in mind the requirements given by a specific user or a customer of the software. it also means that you can easily implement software engineering related terms in Java programming language very easily. In Java programming language you can easily implement concept of inheritance which allows you to copy properties of one class into another. Let's take an example to understand this concept. let's say you have a class of humans. you also have another class called Asian . Asia is also human so you cannot write the same code that you have written for human into Asian class so what you will be doing here you will be inheriting human code into Asian class.  This  creates a parent - child relationship in other words you can say that ‘is a’ relationship.  So this was an example of software engineering. Concepts in the Java programming language  have one-to-one Concepts as well.
## Final words
Learning a programming language is not very difficult these days. the most important thing is to understand the  requirements of the user and demands of Project. If you are looking for a very quick start up and one to bend a website for any kind of startup very small scale project then you should definitely choose Python or JavaScript for building   boat projects.  because using a Java programming language can be very  expensive at the Beginning but when you get your flow then Java will become very powerful and very convenient for you. 
So, if you are really  interested in learning Java then you should install Java 8 or Java 14,  alongside JDK or JRE. First you will simply lemon Java as an object oriented programming language or Java software engineering language. then you will learn Java  Enterprise edition, related web development frameworks and object relational mapping  libraries like hibernate. So keep learning and keep moving forward, I will surely see you in another interesting  article.  till then, take care.
