What is Java used for and why should I learn it?

Having been around since 1995, Java is still relevant and remains one of the most popular programming languages today. It’s estimated that 90% of Fortune 500 companies use Java. So Java is important and relevant, but is Java hard to learn? No. In fact, it is a beginner-friendly language that is extremely powerful. One of the reasons why beginners find Java easy to learn is that it is an object-oriented language. This means Java uses objects and classes, which can easily be reused. This also allows beginners to easily learn how to test and troubleshoot code. Additionally, Java can also be used across different operating systems. Java uses a rich standard library, which is also supported by large tech companies, such as Google and IBM. Other companies where Java is used also includes Netflix, Pinterest, and Airbnb. Java is an evolving language and has the unique ability to combine innovation with stability, which is one of the reasons why Java is still relevant decades later. What is Java used for? Java is most commonly used for backend development, but the language can also be used to build Android apps, desktop and web apps, and handle big data.


Why should I practice Java by building projects?

Project-based learning is a method of learning where you learn a skill through working on a project. This type of learning allows you to learn not only the theory, but also how to apply those skills. By building a Java project, you'll practice the high-level logic of your code and project, and see how each individual line can impact your application. You will also gain problem-solving skills and how to fix it. With so many Java projects available, finding an idea that interests you will make the learning process more fun and sustainable. When you finish building a project, you will have learned and practiced Java techniques, gained problem solving skills, learned how to ask questions, and have a finished project to show off.


How do I know which Java projects are best for learning Java?

The best way to learn Java is to practice Java by building as many projects as possible. There are three factors you should consider when picking the right Java project: your skill level, goals, and interest. You want to have a good idea of your skill level and choose Java practice projects that are not too easy or too hard for you. If you work on Java projects that are too easy, you won’t progress in your coding abilities. However, if you choose projects that are too difficult, you may get stuck, never finish the project, and feel discouraged. Therefore, you want to choose Java projects that are just a little bit above your current skill level. Now, you also want to build Java projects that not only allows you to practice Java, but also lets you show off your skills on your portfolio. So think about the types of Java projects you want to put on your portfolio and jobs you’re interested in as a developer. Think about what your long-term goals are and pick Java projects that align with them. Lastly, you definitely want to choose Java projects that you’re actually interested in and feel connected to. Learning by building Java projects you’re interested in will help you stay motivated. You’ll also be more likely to want to go above and beyond to make your Java project stand out in the crowd.


Can Java beginners learn by building Java projects?

Java projects are a great way for beginners to learn. Two major obstacles beginners face when learning Java are not knowing why you’re learning Java and losing motivation. By learning Java through building projects, you will be able to overcome both hurdles. When you’re learning Java, you may not know how to apply Java theories in the real world. But when working on beginner Java projects, you immediately learn how each line of code impacts your project. By giving theory context, you’ll understand how to apply theories and find more resources to complete your Java project. These Java projects for beginners can also help you build up your portfolio early on. Each Java project you finish can be incorporated into your portfolio to demonstrate your new skills. Another issue that often comes up for beginners is losing motivation. However, when it comes to projects, you can pick a beginner Java project that you’re interested in. Not only will you be more motivated when you work on something interesting, you’ll also want to continue to improve the project. As your Java project comes together, the sense of accomplishment will give you the momentum to keep going, even when things get hard. Additionally, you’ll learn how to approach problems from multiple angles and teach yourself how to search for answers. The ability to problem-solve is arguably one of the most important skills a developer should have.
