Java

Java is a class-based programming language developed by James Gosling and his friends in 1991. Java follows the rule of “write once, run anywhere” because it is a platform-independent language. This approach is further fortified by the Java Virtual Machine (JVM). The virtual machine accommodates Java programs on a variety of operating systems. JVM also helps handle the memory a program occupies.
