It will multiply two numbers sent to it by the the client program, and then return the result. It will have only one method: multiply(). Our server will be a simple calculator program. In general, a server performs some calculations that requested by a client. Here, we have used the Scanner class to take 3 inputs from the user. Choose an operator: +, -,, or / Enter first number 3 Enter second number 9 3.0 9.0 27. To avoid getting bogged down, let's keep our program simple. Example: Simple Calculator using Java switch Statement. One of them will include an object, and the other will call methods on that object.Ĭalling methods of an object that exists in a different program - now that's something we haven't done yet! It's time to give it a try! :) When it comes to RMI, these are just two programs. We don't really need to dive deep into computer terminology. The first thing we need is a client and a server. Does that sound cool? :)Īnd it's not so difficult to do! In today's lesson, we'll analyze the elements of the RMI interaction and figure out how to configure it. It is an object-oriented version of remote procedure call(RPC). You can use RMI to allow two programs to communicate with each other, even if they are on different computers. RMI provides for remote communication between programs written in the Java programming. This stands for Remote Method Invocation. Hi! Today we'll consider a rather interesting topic: Java RMI.
