In the Java platform's distributed object model, a remote object is one whose methods can be invoked from another Java virtual machine, potentially on a different host. An object of this type is described by one or more remote interfaces, which are interfaces written in the Java programming language that declare the methods of the remote object.
Remote method invocation (RMI) is the action of invoking a method of a remote interface on a remote object. Most importantly, a method invocation on a remote object has the same syntax as a method invocation on a local object.
