In this video on RMI Java, we will learn about RMI, which stands for Remote Method Invocation. Remote Method Invocation is a Java API that allows objects to invoke methods on other objects that are running in a different JVM. This is useful for building distributed applications, where you need to have multiple applications communicating with each other.

We will start by looking at the basics of RMI, including how it works and what its benefits are. Then, we will create a simple RMI application. We will see how to create the server and client code, and how to invoke methods on the remote object.

Finally, we will discuss some of the limitations of RMI and when you might want to use another technology instead.

What is RMI?

RMI stands for Remote Method Invocation. It is a Java API that allows objects to invoke methods on other objects that are running in a different JVM. This is useful for building distributed applications, where you need to have multiple applications communicating with each other.

RMI works by using a stub and skeleton pair. A stub is a proxy object that is created on the client side. A skeleton is a proxy object that is created on the server side. When the client makes a call to a remote method, the stub intercepts the call and forwards it to the skeleton. The skeleton then invokes the method on the remote object and returns the result to the stub. The stub then returns the result to the client.

Benefits of RMI

There are several benefits of using RMI, including:

- It is easy to use. RMI provides a simple API that makes it easy to create distributed applications.
- It is reliable. RMI uses a reliable transport protocol to ensure that method calls are delivered and that results are returned.
- It is secure. RMI uses a security model that ensures that only authorized clients can access remote objects.
- It is scalable. RMI can be used to create distributed applications that can scale to handle a large number of users.

@fuzzywun : Small point, and I am sure just a slip of the tongue, but ADF does not point to VOR's. It points to NDB's. (You said it twice). It might help people if you explained what the abbreviations stood for, though I accept that we aviators talk in Three Letter Acronyms (TLA's). A good video though, I have been searching for one to refer my students to, and this fills the bill.
@ibrahimzubair1684 : In 8 mins, I could understand what it took for the instructor 6 hrs to explain, thanks a lot!!!
@jakewerecat9031 : This was so quick & simple and yet so informative! No need for fancy animation, just a good drawing and a good teacher! Thank you!
@solamigos : Very helpful, simplified and straight forward! Much appreciated, captain!
@RakeshKumar-dj5pr : I was just revising radio nav concepts, and I must say this video did the briefing concisely and cleared up most of the confusion I had on the subject. Great job, Cap!
I remember my instructor mentioning something about HSIs commanding correctly over back tracking . I am not sure.. I was wondering if that is of much relevance to actual airline flying?
