It is intended to let application developer 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 milar to C andC++, but it has fewer low level facilities than either of them. As of 2019, Java was one of the most popular programming language in use according to Github, particularly for client server applications, with a reported 9 million developers.
