What is Java?
Java is a high-level, general-purpose programming language created by James Gosling and his team at Sun Microsystems in the mid-1990s. It was originally designed to be a platform-independent language that could run on any hardware or operating system. Java is a class-based, object-oriented language that also supports functional programming. It is compiled into bytecode that can run on any Java Virtual Machine (JVM), making it highly portable across different platforms.
Why to learn Java in 2023?
Java is widely used in the development of web applications, mobile applications, desktop applications, and enterprise software. It has a large and active community of developers who have created a vast array of libraries, frameworks, and tools to make programming in Java easier and more efficient.
Features of Java
Some of the key features of Java include its robustness, security, and scalability. Java has a strong type system and automatic memory management, which helps to prevent common programming errors such as buffer overflows and null pointer exceptions. It also includes a powerful standard library that provides support for a wide range of tasks, including networking, I/O, concurrency, and more.
