What is Java and what does it do?
Java is a programming language that allows developers to create large-scale applications, including games, web applications, and mobile apps. It’s also used in Android app development, which is why many Android apps require Java to function properly. Java is not the same as JavaScript, which is a scripting language used for client-side web development.
In simple terms, Java is used to create desktop applications, mobile apps, and games that can run on any device supporting Java, regardless of the underlying operating system. This makes Java a popular choice for developing cross-platform applications. However, with the rise of newer technologies, Java is slowly being replaced by more modern and efficient programming languages.
Do I need Java on my laptop?
If you’re a casual user who only uses their laptop for browsing the internet, checking emails, and using office software, you probably don’t need Java on your laptop.
