gRPC [Java] Master Class: Build Modern API and Microservices - [Solution] Sum API

The video tutorial guides viewers through implementing a sum function using gRPC. It starts with setting up a new package and defining the necessary syntax. The tutorial then covers defining the calculator service and its messages. Next, it explains how to implement and start the server. The video continues with implementing the calculator service by overriding the sum function and handling requests. Finally, it demonstrates creating a client to test the sum function, ensuring the server and client communicate correctly.

What is the first step in implementing the sum function using gRPC?

• Create a new Java class

• Test the client

• Start the server

• Define the proto file

Which syntax version is used for the proto file in this tutorial?

• Proto 1

• Proto 2

• Proto 3

• Proto 4

What is the purpose of the server builder in the server setup?

• To build and configure the server

• To manage client requests

• To implement the sum function

• To define the proto file

What is the role of the 'sum' function in the calculator service?

• To define the proto syntax

• To create a new package

• To handle sum requests and responses

• To start the server

How does the client communicate with the server in this setup?

• Via a web interface

• Through a direct connection

• Using a managed channel

• Through a command line interface

What is the purpose of the stub in the client setup?

• To manage server shutdown

• To build the server

• To send requests to the server

• To define the proto file

What is the expected output when the client sends a sum request with numbers 10 and 25?

• 10 + 25 = 35

• 10 + 25 = 30

• 10 + 25 = 40

• 10 + 25 = 45
