Java's popularity stems from its portability, robustness, and widespread use in various applications. Java's design allows applications to be developed once and run seamlessly across different platforms, as long as they have a Java Virtual Machine (JVM) installed. The language's excellent performance, rich library ecosystem, and vibrant community support significantly boost its attractiveness. Additionally, Java's use in enterprise environments, Android app development, and large-scale systems solidifies its status as a leading programming language.
