How to Learn Java

Java is both an object-oriented programming language and a software platform. Developers value Java because it is portable across platforms and adaptable to a wide range of contexts. You may want to learn Java if you are interested in becoming a Software Developer, Web Developer, Mobile App Developer, Data Scientist, Game Designer, User Experience Designer, or Laboratory Scientist. Knowing Java makes one a desirable employee in many industries because of its flexibility. The number of options for learning Java might be overwhelming at first glance. There are books, video tutorials, classes, and more to choose from; it all depends on your learning style and personal preferences. 

Here, we’ll discuss the various methods of learning Java so you can decide how you’d like to get started.

What is Java?

Java is both an object-oriented programming language and a software platform in itself. Its creators designed it as a “write once, run anywhere” tool. It is portable, scalable, and adaptable. An app created in Java can function across multiple platforms and over distributed networks. This flexibility makes the Java language widely useful and Java coders highly desirable to employers. Professions that use Java include Web Developer, Mobile App Developer, User Experience Designer, Data Scientist, Game Designer, and Laboratory Scientist.

Java’s modular nature allows developers to take existing pieces of code that are useful to them and then combine those modules in a new context for a new purpose. Also, programs in Java do not need to be compiled because the virtual Java Runtime Environment tool interprets the code and translates it for the computer you are using. Java’s portable and adaptable nature allows it to serve a wide range of use cases. For this reason, it has become the chosen tool of key players in the technology space: for example, the Android operating system is based on Java code. In addition to being critical for mobile app development, Java is also a crucial skill for Web Developers. It is also used for data science, game design, user experience design, and scientific applications. Many employers are eager to hire Java coders because the language is highly flexible, with many possible use cases and adaptations to new contexts.

What Can You Do with Java?

Knowing Java means you can code across multiple operating systems and hardware architectures without modifying your programs for a new environment. Because it is an object-oriented programming language, Java allows you to create modular units of code that you can reuse in any Java program, even across platforms and environments. You can quickly adapt code created for one use case to apply in another, as Java is highly flexible and adaptable for novel contexts. So as exciting new technologies arise, your knowledge of Java will remain relevant and desirable to employers.

Using Java also speeds up the development cycle. This is due to its unique interpretation process, which allows developers to sidestep much of the routine testing and debugging necessary when coding in other programming languages. You can use the Java Runtime Environment to keep your applications robust with its automatic memory management. The JRE also supports robust graphic interfaces through multithreading. Another advantage is that its built-in virus and tamper protection keeps your code secure.

With Java, you can build mobile applications for the Android platform and, in some cases, for iOs. If you’re into big data, you can use Java to analyze large datasets with open-source tools like Hadoop and Spark. Java’s “write once, run anywhere” functionality makes it perfect for writing cloud-based applications and powering data collection within them. Though machine learning is typically associated with Python, libraries such as Deep Learning for Java and MLib make it easy to take advantage of Java’s speed and security by providing a stable environment for deep learning or machine learning processes. Another great application for Java is programming smart household devices. Java is also useful for game design, both mobile and desktop. 

In-Person Java Training

Taking classes in person is the most traditional method of learning any skill. It can be useful to be in the same room as a knowledgeable instructor and fellow learners who can help you along. Class schedules and deadlines can also motivate you to study consistently. Studying in-person lets you avoid potential technical difficulties that can emerge when trying to access classes online. On the other hand, you will need to get to class, which takes more time than logging into an online course from home. Also, some students may find the social aspect of in-person learning more distracting than productive.

Noble Desktop offers a beginner-friendly Java Bootcamp that begins with the fundamentals of Java before moving to advanced topics like recursion and arrays. This is a good option for local students and those who can manage a weekend commute from nearby areas like Philadelphia or New Jersey. If you’re not near NYC, you can search for other in-person Java classes in many metropolitan areas, including Los Angeles, Chicago, Washington D.C., and Seattle.

Live Online Java Training

Virtual training is increasingly popular today. Live online instruction gives a student the advantage of working directly with an instructor without commuting. You can still ask questions and get feedback in real time. Some students may also find it easier to concentrate when doing online learning from home. However, others may feel the lack of social interaction that comes with in-person learning. Online learning can also come with logistical difficulties, as technical problems may hinder the student’s consistent access. However, depending on your schedule, it may be worth dealing with some possible technical issues if it means saving time. Another consideration is that you will have to use your own computer to pursue online learning. However, this creates fewer issues when learning a programming language than if you were studying a skill like graphic design that required running a large, complex application.

If this option is right for you, you can take a live online Java bootcamp through Noble Desktop from anywhere. The program holds classes on a weekend basis, meaning many students can learn while maintaining their current schedules. You can also search for other live online Java courses from providers like ONLC Training Centers, Code Fellows, and NextGen Bootcamp.

Free Online Courses & Tutorials

If you’re not ready to take on an entire course yet, you can still discover the world of Java through the many free online resources available. Udemy offers a free introductory course for absolute beginners. They also have free tutorials on specialized topics, like integrating Java with MySQL, that you might want to check out later in your Java studies. The free Introduction to Java course on Coursera will take you through the operators and syntax you’ll need to write simple Java code. Udacity and freeCodeCamp each offer several free Java courses, including beginner programs. Free courses are a good option for students to learn the basics of Java, but if you want to delve deeper, you’ll likely benefit from making a financial investment in your studies.

On-Demand Java Classes

Some students prefer to learn using on-demand Java courses. The advantage of on-demand Java training is that it is much easier to fit into a busy schedule. Not only does it not require a commute, but you can do it whenever you have time. However, using on-demand materials for your study of Java means you don’t have access to a live instructor, so you won’t get the benefit of clarification and feedback from an expert when you have a question. On-demand courses also require more self-discipline, as students must keep themselves on track in their studies. If you’re confident you can stay focused and work with a busy schedule, studying Java in a self-paced format may be the right fit.

For those starting out, a free self-paced course might be a good option for learning the basics. You can find free introductory Java courses on Udemy, Coursera, and Udacity, among other providers. However, if you’re looking to go beyond the basics, you’ll probably want to invest in a paid course. With a platform subscription, you could learn intermediate Java using Skillshare or discover how to build simple Android apps on Codecademy. There are many options out there for learning Java skills on-demand.

Which Learning Method is Right for Me?

Given the many different resources available to help beginners learn Java, you might be unsure which one is best for you. Everyone has different learning styles and preferences, and you can experiment with multiple tools to see which one feels right for you. One of the great things about directing your own learning is that you get to pick which combination of tools you prefer; you don’t have to stick with what a teacher chooses.

One factor you’ll want to consider is your goal in learning Java. Are you brand-new to coding and trying to change careers? Then you may want the interactive aspect and intense timeline of a Java-focused bootcamp. Or do you already know how to code and simply want to add another language to your toolbox? In that case, a self-paced course may serve your purposes.

Another relevant item is how much time and money you are willing to invest in your Java studies. On-demand courses tend to be cheaper and fit various schedules, while in-person and live online courses often require more time and a larger financial investment. If you are still trying to figure out how seriously you want to study Java, on-demand courses may be a good option for exploring your interest and deciding what you’d like to do next.

Also, you’ll want to think about how you learn best. Does the social aspect of studying alongside others help stimulate your learning process, or do you focus best at home, in surroundings where you are comfortable and less likely to be distracted? Do you have the self-discipline and internal motivation necessary for success in a self-paced course, or do you function better with deadlines and expectations assigned by an instructor?

It’s also essential to consider your current schedule before selecting a learning method. If you have many responsibilities like a full-time job or family commitments, you may not be able to devote time to a structured course that requires you to attend at the same time every day. In this case, a self-paced class or video tutorials may be better since you can access them when your schedule allows. On the other hand, those with a more flexible schedule may prefer a structured course offered in-person or live online.
