In computer programming, Java is one of the most preferred languages for software development. Understanding and learning Java will create many opportunities for you as a developer in the field of Computer Science.
It does not matter with your end-goal or skill level; you can start whenever you want. In this article, you will be offered some great reasons to learn Java from the best Java training institutes in Vizag.
Why Should You Learn Java?
Java Is Easy To Learn
- The main features of Java include object-oriented, high performance, interpreted, secure, and multithreaded language. You must be thinking about what all these things mean? Java eases the process that is required to make a good network connection.
- It is highly secured to safeguard the models against the viruses. Java is written statically; therefore, it becomes easy to track down the errors in the code. For absolute beginners, Java is a great language to start with programming.
Java is Popular
- Being one of the most used programming languages globally, Java is a common and highly demanded language. Moreover, it is the second-largest community on StackOverflow. It justifies that there is a wide range of variety of support for Java programmers and learners.
- If you find yourself stuck in any question, your doubt can be cleared by someone on the forums online. And with a good and developing ecosystem of developers, you always have a chance to learn something exciting.

Java Can Deal With Real-World Problems
- The main highlight of Java is its “write once, run anywhere” property. It indicates that code written and compiled in Java can run on different platforms without recompiling them. Therefore, Java can be used in all kinds of distributed environments. According to Oracle, Java runs in over 3 billion devices worldwide, like Blu-ray players, game consoles, and Android phones.
- Java is so popular that it is being used by the financial service industry and also NASA. Java is widely used in real-world applications, and there is no limit to it.
Java Can Boost Your Career
- Java helps us in solving real-world problems; therefore, there is a wide range of opportunities for Java programmers. Java is mostly demanded in all the companies irrespective of its sizes and scopes.
- It is the highly used programming language by most employers both inside and outside the high-tech industry. It is estimated by some industries, that around 90% of Fortune 500 companies use Java in some of the other jobs.
Java Skills are Transferable
How To Start Learning Java?
There are several steps required to learn Java and do basic vocabulary to get started.
Make your motivation tangible
When compared to others, learning Java can be more comfortable, but at the same time, it is challenging too. To master it properly, you need to study and practice daily. Without any hard motive, you will find it very difficult to master the language.
If you have a clear motivation, it can push you constantly along the challenges and keep you determined and focused on your learning. Your starting motivations can be of type either developing a small game in Java or getting a full-time career as a Java developer. Making these types of goals can help you redirect your focus and help you better measure your progress.
Create an Education plan
- In the journey of learning Java, make discipline as your new friend. By creating a plan for your learning, it can make you a good Java learner. Vy having a plan, you will get to know when and what to study.
- You should begin by making a weekly curriculum starting with the basics. Most people want to know how long it takes to master Java. Of course, there is no particular answer to this question. But the fact is, a devoted and committed learner will surely learn faster and smarter.
- If you are thinking significantly and thoughtfully about your future, you must give at least 2 hours daily and 4 hours on the weekend to study Java programming language. And if you go through this plan regularly for 5-7 months, then you will be ready to apply for a job as a Junior Java Developer.
Some of the general topics, you need to cover are-
- Java Syntax
- Object-Oriented Programming Concepts
- Core Java
- Java Collections
- Libraries and frameworks
- Different APIs
You should make a plan that goes along with these topics. One thing to note is your timing will depend on the knowledge of other languages and the method of learning; you are approaching.
Download Java Development Kit (JDK)
- It is an environment provided by the Java community where you can document and run Java applications. It consists of all the basic tools required for writing and developing Java code. This package consists of Java Runtime Environment (JRE) and Java Virtual Machine (JVM).
- JRE supports all the libraries and components required to execute the code and run the applications. JVM is used to run your bytecode and execute your code on any platform.
However, you can avoid this step if you find it a little challenging to download JDK. You can start with courses that offer an embedded ecosystem.
Start with the basics
Even if you know other programming languages, a strong introduction to Java is very important for building a foundation and ensuring success. After learning the process of compiling the code and fixing the errors, you can try the next learning stage. You should first try to learn these concepts-
What is Java Syntax?
Like different languages, programming languages, too, have some set of rules and syntax to make meaning. Java is a case sensitive language and has its own syntax. All the codes from declaring the data types and variables to using the operators have a unique syntax.
What are identifiers?
Identifiers are used in creating the names for all the Java elements. They are used to refer to an item later in the program. There are some basic rules for identifiers
- They are case sensitive.
- They must start with a letter (A to Z or a to z), underscore(_), or dollar ($).
- They should not be a keyword.
What are the operators?
They are the symbols used to perform any operations or functions. There are various kinds of operators like-
- Arithmetic Operators - They are used in mathematical expressions. Eg- +, -, *, /
- Relational Operators - They are used to compare different values. Eg- <, >, =, <=, >=, !=
- Logical Operators - They provide the boolean result either in the form of true or false. Eg- &&, ||, !
- Bitwise Operators - They are used to perform operations on single bits of the number. E.g., long, int, short, char, byte
- Assignment Operators - They are used to assign any value to the right side of the variables. E.g., age=5
What are the keywords?
They act as reserved words used to define predefined meanings or functions. There is a whole list of keywords that you can look at on the Oracle website.
What are Data Types?
Data Types are used to identify the values of different variables and what type of operations can be applied to them. There are two kinds of data types in Java programming-
- Primitive Data- These are predefined data types that come along with Java language and are reserved with keywords. They are boolean, byte, char, double, float, int, short, long.
- Non Primitive Data- These are not predefined data types and are created manually by the programmer. They are Classes, Interfaces, and Arrays.
What is an object?
An object is used to combine data with a state (attribute) and behavior (method). The main benefit of Java being an object-oriented programming language is you can organize your programs around objects.
Balance your theory and practice
- Once you have gone through the basics clearly, the next step is to practice it. Learning only the theoretical part will not help you for a longer time. Apart from learning theory, if you do hands-on projects, you will be mastered more rapidly.
- Doing live projects will help you in boosting your confidence and developing a good personality in an interview. You must practice by writing your code and designing your algorithms. Every day you will learn something new from the previous mistakes.
- Theory and practice are related to each other, and therefore, you need the right balance between both. You cannot leave any one of them entirely; else, your foundation will be weak. However, it is recommended that giving 20% of your time on theory and 80% on real projects will master your Java skills.
We all are familiar with the fact that starting a new language to learn can be a little tedious for some people. Therefore, you need to decide before joining any institute for Java training in Visakhapatnam.
