java rmi example code

java rmi (remote method invocation) is a powerful api that allows for the invocation of methods that are located on remote java virtual machines (jvms). it enables developers to build distributed applications in java, where objects can interact with each other across different jvms.

### overview of java rmi

2. **remote object implementation**: this class implements the remote interface and contains the actual logic for the remote methods.

3. **rmi registry**: this is a simple naming service that allows clients to look up remote objects by name.

4. **client**: the client will look up the remote object in the rmi registry and invoke methods on it.

### example: simple rmi application

let’s create a simple rmi application that has a remote service that adds two numbers.

#### step 1: define the remote interface

#### step 2: implement the remote interface

#### step 3: create the server

#### step 4: create the client

### step 5: compile the code

compile all the java files. you can do this in your terminal or command prompt:

### step 6: run the rmi registry

before running the server, you need to start the rmi registry. open a terminal and run:

make sure you run this command in the directory where your compiled classes are located.

### step 7: run the server

in a new terminal, run the server:

### step 8: run the client

in another terminal, run the client:

### expected output

when you run the client, you should see:

### summary

this tutorial covered the basics of creating a simple java rmi application. you learned how to define a remote interface, implement it, create a server to host the remote objec ...
