gRPC [Java] Master Class: Build Modern API and Microservices - Unary API Server Implementation

This video tutorial guides viewers through implementing a unary greet RPC service using gRPC in Java. It covers setting up the server, creating a new Java class for the greet service, and implementing the service by overriding methods. The tutorial explains how to handle requests and responses using gRPC's stream observer and finalize the RPC call. The service is then integrated into the server, making it ready for client interaction.

What is the purpose of creating a new Java class named 'greet service impl'?

• To manage database connections

• To implement the greet service logic

• To define the server configuration

• To implement the client-side logic

Which method is overridden in the greet service implementation?

• start()

• execute()

• greet()

• initialize()

What is the input type for the greet method?

• GreetResponse

• GreetRequest

• Integer

• String

How is the response sent back to the client in the greet method?

• Using a direct socket connection

• Using a return statement

• Using a callback function

• Using a stream observer

What is the final step in the greet method after sending the response?

• Sending an acknowledgment

• Closing the server

• Completing the RPC call

• Logging the response

Which method is used to add the greet service implementation to the server?

• registerService()

• attachService()

• includeService()

• addService()

What message is displayed when the server is running without a client?

• Hello World

• Server Ready

• Hello GRPC

• Client Connected
