`ManagedChannelBuilder` is a class in the gRPC Java API for creating gRPC channels that manage their own lifecycle. Here's a simple demo to show how to use `ManagedChannelBuilder`:
```java
import io.grpc.ManagedChannel;
import io.grpc.ManagedChannelBuilder;
public class ManagedChannelDemo {
public static void main(String[] args) {
// Create a managed channel builder
ManagedChannelBuilder<?> channelBuilder = ManagedChannelBuilder
.forAddress("localhost", 8080)
.usePlaintext();
// Build the managed channel
ManagedChannel channel = channelBuilder.build();
// Use the managed channel to make gRPC calls
// ...
// Shutdown the managed channel when done
channel.shutdown();
}
}
```
In this demo, we first create a `ManagedChannelBuilder` object using the `forAddress()` method to specify the address and port of the gRPC server we want to connect to. We also call the `usePlaintext()` method to allow insecure connections (i.e., without SSL).
Then, we use the `build()` method to build the managed channel. We can use this channel to make gRPC calls to the server.
Finally, we call the `shutdown()` method on the managed channel when we're done using it to release any resources it may have acquired.
