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. 

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

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.

Free Intro 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.

Comparing Online Methods with In-Person Learning 

In-person, live online, and on-demand Java training all have their advantages. Real-time classes, such as in-person and live online, are more engaging because they are interactive. Working directly with an instructor allows you to ask questions as they arise, receive feedback on your work, and get guidance when building projects for your portfolio. Interacting with peers is another benefit of real-time training. A live class also imposes deadlines and a structure that can help you organize your time as you pursue your studies.

Those who thrive on social interaction will particularly benefit from in-person training and the networking opportunities it offers. With in-person training, you can avoid potential logistical complications from technical difficulties. Schools also often provide up-to-date equipment for students to use in their learning.

Live online training provides access for those who do not live near a major metropolitan area or cannot devote time to a commute. It can also be advantageous for those who focus best at home, perhaps finding social interaction distracting. However, others might miss the stimulation of in-person group learning. Learning online also means you’ll need to provide your own equipment, and technical difficulties may sometimes interrupt the process.

On-demand learning is generally the most affordable option, making it a good way to learn the basics. It can also be a better fit for those with a busy schedule. However, those who choose a self-paced course do not get the benefit of clarification, feedback, and guidance from a live instructor. Also, on-demand materials are sometimes outdated, especially after a Java update is released, which happens about every six months. 

Tips to Succeed when Learning Java Online

Learning Java online can be challenging, especially if you choose an option that doesn’t provide the support of live instruction. However, if you do choose to learn Java online, there are several smart moves you can make that will facilitate your learning process. For the most effective online learning, try these tips.

  • Start with the basic concepts: You’ll want to learn what object-oriented programming is and what makes it different from other types of coding. Then you should familiarize yourself with Java's basic functions, data types, and classes. This will help prepare you to tackle its tricky syntax. 
  • Practice: As with any other skill, the more frequent, sustained, and regular your practice is, the more quickly you’ll learn. With on-demand courses, you’ll need to make sure you set a study schedule, as you won’t have the regular class meetings and deadlines provided by a live instruction format.
