You must have a fundamental understanding of logic and programming in order to study Java. It is also advantageous to be familiar with Object-Oriented Programming (OOP) principles.

Java can be used to create a wide variety of applications, including desktop, web, mobile, and enterprise apps.

Your existing programming experience and level of understanding will determine how long it takes you to learn Java. You can learn the fundamentals of Java in a few weeks with regular effort, but it may take many months to grasp more complex Java ideas.

Platform independence is a feature of the object-oriented programming language Java, allowing it to execute without the requirement for recompilation on any platform. Java has a huge standard library and is far more scalable than many other programming languages.

Java programming exercises include resolving coding issues, taking part in coding competitions, and creating projects. Additionally, there are numerous online tools and coding communities that provide projects and practice tasks.
