Java is a high-level, class-based, object-oriented programming language designed to have as few implementation dependencies as possible. In addition, it is a general-purpose programming language intended to let application developers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.
Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++ but has fewer low-level facilities than either of them. In addition, the Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. According to GitHub, as of 2019, Java was one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers.
