Programming is one of the important job fields these days. Our most favourites websites and software are all developed by programming in multiple languages. Programming or coding in Java is most popular these days. You may be considering learning Java but you do not have any technical experience. We will guide you through how to learn Java with no programming experience.

Why are you learning to program?
Before we begin with learning Java with no programming experience whatsoever, you need to ask yourself why you will be a programmer. Do you see programming as a nice to have skill? Do you want to create a side hustle out of it? Do you want to take it as a full-time career as your whole life depends on it? You need to ask all of these questions and more. Having a distinct how and why will keep you consistent in your struggle. If you’re unaware or doubtful about your reasons, it will desist you from delivering your best. Mind that deeper self-awareness brings you higher levels of self-efficacy.
Java is a class-based, high-level, object-oriented programming language. It is currently among the most preferred programming languages for developers. Java is used for a wide range of things.
- Computer Softwares
- Web applications
- Mobile apps (mostly android versions)
- Database connection
- Application and web servers, and more
History of Java
Java was designed by James Gosling in Sun Microsystems company in 1995. It was introduced with the help of JDK (Java Development Kit) containing a JRE (Java Runtime Environment). And the JRE contains JVM (Java Virtual Machine) and other software tools. For example, Java application program interfaces (API). The Java API & JVM help the development of Java applications.1.0 was the very first version of the Java Development Kit. And the Java SE 10 is the latest release of Java Standard Edition.
Why learn Java to get started?
After you have a clear perception of “Why are you learning to program?” The next question you gotta ask yourself is, “Why only Java to get started?”. If a personal project demands it or you foresee yourself doing Java-based projects, you get your answer. But if you still don’t know why only Java, then let’s help you with it.
Java is a recommended language to begin learning to program. Its object-oriented approach makes it easier to elaborate on the core computer science concepts. In addition, Java provides a detailed and comprehensive way to implement the variables, arrays, classes, encapsulation, inheritance, polymorphism, data structures, in-built garbage-collector and interfaces.
One of the best ways to get acquainted with the core Java components and features is to woodshed a java blog that can provide structured data. This option may substitute long video lessons or programming lectures for beginners and serve as the help guide filled with practical tips and theory. Having the possibility to refresh some necessary topics from the list makes the learning process faster and more independent, which means that you can study at your own pace. User success stories contribute to the inspiration of a programmer-to-be as well.
If talking about the options available in the educational niche, CodeGym java blog can serve as an alternative for busy people who are in need of coding skills and want to adjust their schedules to the learning curve.
Some of the noteworthy Java applications are as follows.
- Web Apps
- Mobile Apps
- Desktop Apps (with GUI)
- Enterprise Level (scalable) Apps
- Embedded Apps (image/motion detection in cameras)
- Web Apps with App Server (use of microservices, Apache Tomcat / J2EE Server etc)
Resources to learn Java
CodeGym is an online platform for learning Java. The platform suggests completing 1200+ tasks for learning to program in Java. You will write a lot of code since registering for their course. This will help polish your skills and eventually land a job in the programming or developer field. The storytelling and gamification techniques will help you be motivated and engaged throughout the course.
To learn Java online, Codecademy is one of the best places. For both beginners and experienced developers, the platform provides free courses for the Java programming language. You will have the opportunity to work on different projects where you can implement knowledge the knowledge you have gained from the course, such as creating a calculator.
Some key topics you will learn are as follows:
- Introduction to Java
- Data structure
- Object-oriented concepts in Java
Renowned e-learning platform Udemy has multiple courses on Java programming language. The two popular courses for learning java on Udemy are: “The Complete Java Masterclass”, and “Java Programming for Complete Beginners”. You will be able to learn from scratch. Key concepts you will learn are:
- Java Collections
- Exception handling
- Multithreading and Concurrency
- Functional Programming Networking
- File handling.
Coursera is another renowned online learning platform. This, like Udemy, has quite a few courses to learn Java as a beginner. Some courses are available in multiple languages. You can also turn on subtitles for languages from the courses’ preferences.
Establish an Action Plan
Since you’re firm about learning Java, the first step you need to take is to develop a personal schedule. There’s no universal rule of learning things that work out for everyone. And there’s no standard path as well. However, we are suggesting to you what works for most people. You can observe your learning patterns and pick what’s best for you.
Jot down all the concepts to define your destination. Allocate a certain number of hours each day for theory and practice separately. You need to create a step by step outline going from easy to hard of all the aspects you aim to master.
Focus on Core Concept
A sound plan will help you break down your journey. Take it one step at a time, with a concentration on learning. Take your due time, and don’t leap forward until you’re confident about a concept. You might feel overwhelmed with your progress initially but remember going slow is far better than going wrong. It’s okay if things seem challenging in the beginning. But realising in the middle of a production-level app that you’ve implemented a concept wrong can leave you in hot waters.
Your points of focus have to be the fundamentals of programming, OOP, data structures and algorithms. You can further break it down to syntax, objects, classes, methods, java-based data structures, collections, exception handling, file handling (I/O streams), algorithms, time complexity and optimisation, unit testing, lambdas, etc. If this list gives you cramps in your stomach, take a deep breath and just follow your schedule.
Consistency is the Key!
The plan is of no use if you do not work on it with steadiness. If you’re not coherent with your plan, soon you’ll find yourself stuck back, overburdened and might want to quit. Do not let your work pile up and scare you. As they say, a stitch in time saves nine. This might be a small tip, but showing up every day will boost your morale and take you far ahead from the crowd.
Practise will Keep You Afloat
Most beginners fail to balance between the concepts and code. You learnt a concept. Oh well, now don’t be sure you’re good at it till you solve multiple problems of different dimensions on it. Programming is 20% theory and 80% coding practice. Ensure you practise long enough until solving a problem doesn’t feel like a big thing to you.
So let’s wrap it up with stressing upon determination and practice. May your drive take you to your destination, and may your work ethic help you grow every day. Cheers!
