gRPC [Java] Master Class: Build Modern API and Microservices - Bi-Directional Streaming API Client Implementation

The video tutorial covers the implementation of a bidirectional streaming API client. It begins with setting up the client function and managing server responses. The tutorial then demonstrates generating and sending requests using Java 8 features. Finally, it tests the client, showcasing the power of bidirectional streaming by sending and receiving messages asynchronously.

What is the primary purpose of the bidirectional streaming API discussed in the video?

• To improve server response time

• To send data in one direction only

• To allow simultaneous sending and receiving of data

• To handle errors in data transmission

What is the role of the countdown latch in the implementation?

• To handle server errors

• To increase the speed of data transmission

• To synchronize the completion of tasks

• To manage the number of requests sent

How does the server indicate it has finished sending data?

• By sending an error message

• By sending a special end message

• By closing the connection

• By triggering a countdown latch

Which Java feature is used to iterate over the list of names in the implementation?

• Java 7 for loop

• Java 9 stream API

• Java 8 Lambda function

• Java 6 while loop

What is the expected outcome when sending multiple names to the server?

• The server will respond with a single message

• The server will respond with multiple messages

• The server will not respond

• The server will send an error message

What is demonstrated by adding a delay between sending requests?

• The server's inability to handle delays

• The synchronous nature of bidirectional streaming

• The client's inability to send requests

• The asynchronous nature of bidirectional streaming

What is the significance of using 'System.out.println' before sending each name?

• To log the sending of each message

• To log the client's error

• To log the server's response

• To log the completion of the process
