Java, being one of the popular programming languages preferred by developers and businesses, there is a high demand for Java programmers. The few major reasons behind Java’s popularity are its features such as open sources/free libraries, versatility, meticulous documentation, user-friendly, huge support community, and multi-feature. Compatability is a key highlight in terms of its functioning on desktop and mobile devices, web applications, web servers, games, application servers, client-side validations, database connection, and others.
Why learn Java?
Learning Java is beneficial in many ways as compared to other programming languages. The advantageous factor in learning Java is rooted in the seamless performance of any task with numerous plugins and rich libraries. The code once compiled can be used anywhere with Java’s platform independence at the binary levels and source-code. The codes are free from bugs and are reusable as independent modules from which the codes are split are made possible by Java’s object-oriented feature.
This programming language can function on a cross-platform with several security features. After Python and R, Java is the most preferred choice for machine learning and data science. The majority of the web applications and web pages are built and developed on the independent platform of Java making it popular among designers and developers. According to payscale, the average salary for a program developer or Java programmer in India is ₹617165.
Ways to Learn Java
With codes that could be used anywhere, Java is one of the programming languages that are easy to learn as well as to gain conceptual understanding. Beginners who have set up IDE on their systems can try out a simple program on Java as follows:
a) Open a new project with a name of your choice. Let’s use ‘JavaLearning’ as a new project.
b) Create a package with the name ‘learning’.
c) Within the package, you may create a class named JavaLearning.java. Add the main method: public static void main (String args) on the checkbox.
d) In the main method, add the following code:
System.out.println (“Welcome to Java”);
The code given will appear as a message on the console once the program is run as a Java application.
This simple program can help you pick up with programming and eventually you will be able to work with keywords and modifiers while advancing in Java. Look for methods and tutorials that include both free and paid to gain experiential learning. For beginners, learning about Object-Oriented Java Programming concepts, collections, Generics, control flow statements, network programming, and intermediate Java topics such as core Java skills, Spring framework, JavaEE, Android development and focus on Java 8 and 11.
In terms of specialization, learners can cover data structures, performance tuning, advanced data structures, opportunities, and tips for Java interviews. Lectures and real-world projects from Google are advantageous for your study. It is important that basics such as OOP concepts, interfaces, and working with classes are learned thoroughly and gradually learning how web applications are developed using Java. Projects have to be done on different levels for practice. Arrays, conditionals, Strings, ArrayList, Inheritance, etc. are major portions to be covered along with understanding compile-time, debugging exceptions, and run-time errors. Persistence API, web fundamentals, threads, collection (LinkedList, Map, Tree, etc.), exception handling, and Java design patterns are the intermediate topics.
From a perspective of learning and seeking opportunities in the field of Java programming, LinkedIn offers a range of short courses. To begin with, Learning Java, Introduction to Data Structures & Algorithms, and Learning Java provide better learning as they guide learners through introductory and advanced concepts in Java and one will also be able to find career opportunities in Java.
Once you have gained an in-depth understanding of Java, you may take up top Java certifications that will help you boost your profile especially if you wish to seek a career in the software industry. The top few Java certifications include Oracle Certified Master, OCAJP and OCPJP, OCEWCD, Spring Professional Certification, Apache Spark Cert HDPCD, AWS Solution Architect, Professional Scrum Master, and Project Management (PMP).
