Java is currently one of the most demanded languages in the IT Sector. On starting your programming quest, a lot of questions would pop in your head like how to learn Java? What resources are available for a novice? How do we master Java and how long would it take?

In this blog, we explore the vast inventory of Java learning resources available all across the Internet and strategies to implement to learn Java quickly.

About Java

Java is currently one of the top preferred programming languages. Its scalability, platform independency, and multithreading make it one of the most demanded robust programming languages in the IT Industry.

Developed in 1995 by James Gosling at Sun Microsystems’ Java was initially called Oak, and later acquired by Oracle Corporation.

Java skills are required in many significant domains of Technology – Cloud Computing, Artificial Intelligence, Game Development, Data Science, etc.

A high-level, Object-Oriented Programming Language Java is known for its platform independency running seamlessly on any platform without the need for recompilation. Java is considered architecture-neutral as it is independent of the system architecture. 

Inheritance and polymorphism contribute significantly to Java’s feature of code reusability. A function, once written, can be called multiple times over and over again, speeding up the programming procedure.

For anyone with prior knowledge of C++, the transition to Java will be smooth and undemanding.

Why should you Learn Java?

Java is an Object Oriented Programming Language where classes are created to define the structure of objects. The key features of Java that make it stand out in the 2024 market are:

1. Object Oriented Programming Language

The basic concepts of OOPs are:

Inheritance – Inheritance in Java is a mechanism in which a subclass/child class inherits the properties (variables, functions, and methods) of the superclass/parent class.  

Its main target is the hierarchical organization of functions and code reusability.

Polymorphism – Polymorphism in Java is a mechanism that allows objects of different classes to be used as objects of common classes.

Its main objective is code reusability.

Abstraction – Abstraction in Java is a mechanism that shows only the key details of the object and hides the rest. 

Its main target is to attain security. 

Encapsulation – Encapsulation in Java is a mechanism that clubs variables and functions together into one single unit. 

Its main target is to prevent unwanted modifications to the code.

2. Platform Independent

Write Once Run Anywhere (WORA) makes Java more advanced than other programming languages in the market.

The ability to run on any system irrespective of the underlying architectural system contributes to Java’s portability and widespread adoption.

How to learn Java fast

1. Start with the fundamentals of Java

Familiarizing yourself with concepts like Variable Declaration, Function Overloading, Method Overriding, Constructor Overloading and basic concepts of OOPS is the right kickoff for your Java learning journey. 

Basic Java Programs which would strengthen your foundation of Java include: 

  1. Write a Java program to display a sentence, store integers, characters, and strings, and display them.
  2. Write a Java program to solve easy mathematical problems without using any inbuilt functions.
  3. Write a Java program to check a boolean condition using conditional statements.
  4. Write a Java program to create a function, call it, and create an object for the same.

Once these concepts are clear, move to Arrays. Perform elementary operations like Searching, Sorting, Deleting, and Insertion.

Once thorough with these concepts beginners can move to Recursion, Stacks, Queues, and Binary Trees for a higher level of complexity.

2. Make flowcharts to understand the concept

A flowchart would help you give a visual representation of the flow of your thoughts while writing a code. 

While debugging it is easy to check for errors in a flowchart.

3. Write code regularly. This will help with learning the syntax.

Learning the syntaxes is the elementary step for writing Java code. Each keyword used in the syntax has a predefined meaning and it is essential to understand the technicality behind it. 

Writing the syntax time and again would ingrain them in muscle memory over time. 

4. Dry run a code

To understand the logic of a code it is essential to walk through the code before you compile it. This would help detect logical errors, if any, the values that the variables take at different stages and contribute to the learner’s critical thinking ability and coding skills.

5. Debugging a code

Debugging helps drastically improve coding skills as it assists the programmer in understanding when and where an error can arise. The error can be Syntaxial, Run time, or Logical.

Isolating complex sections of the code and walking through them gives you a clearer idea of the logic behind it.

6. Work on small projects

Working on mini projects like building a calculator, a sudoku game, or a networking app would help you get deeper into the subject, explore more alternatives, and learn new concepts.

7. Work On Unstructured Projects

Working on unstructured projects that require you to code from scratch without any architectural base would help you realize where you stand in the realm of coding, areas you need to work on, and concepts that are yet to be tackled. 

8. Engage With Experts

Interacting with experienced programmers about their Java learning journey would make novices gain confidence. You feel a sense of belonging in your struggling arc.

Experience is the best teacher. Sharing perspectives, ideologies, and learning techniques would help you boost your journey.

9. Teach Beginners To Remain Thorough With The Concepts

One effective way to enhance your Java knowledge and to have a deeper insight into the older concepts is to teach novices. 

Along with brushing up on your Java concepts, you will be in touch with what the market has to offer currently in the domain of Programming Language. 

Conclusion

Choosing one source among the plethora of Java resources available can be confusing for beginners. Researching before starting to study is essential. Staying updated with the current trends would help individuals understand the needs of the market and what measures they need to take while studying to tackle the need.

Research about what method of teaching aligns with your method of learning. For in-depth knowledge, it is essential learners opt for tutoring as their choice as that would help them clear their fundamentals which are needed later for mastering the language. For self-study, learners can opt for a course that would help them have recorded videos available. Any doubt arising can be dealt with by the tutor.
