If you’re looking to enhance the readability and efficiency of your asynchronous code in Java, EA Async is the tool for you! It implements Async-Await methods, allowing you to write non-blocking code in a sequential style. This blog will guide you on how to integrate and use EA Async effectively in your Java projects.

Why Use EA Async?

• It simplifies asynchronous programming, making your code easier to read and maintain.
• It optimizes scalability by freeing up worker threads while waiting for other processes.
• Inspired by .NET’s Async-Await, it brings familiar patterns to the JVM environment.

Getting Started with EA Async

Before you dive into coding, let’s ensure you have the EA Async library set up in your project. EA Async supports Java versions 8 to 10 and is compatible with other JVM languages.

Step 1: Include the Dependency

For Maven users, add the following dependency to your pom.xml:

    com.ea.async
    ea-async
    1.2.3

For Gradle, include this line in your build.gradle:

implementation 'com.ea.async:ea-async:1.2.3'

Step 2: Instrumenting Your Code

To utilize EA Async, your project needs to be instrumented. Here are the options:

• Option 1: Start your application with a JVM parameter:

java -javaagent:ea-async-1.2.3.jar -cp your_classpath YourMainClass args...

• Option 2: In your main class, call Async.init(); at the start.
• Option 3: Use the EA Async runnable jar to instrument your existing classes.
• Option 4: Preferred build-time instrumentation using the ea-async-maven-plugin.

    
        
            com.ea.async
            ea-async-maven-plugin
            1.2.3
            
                
                    
                        instrument
                        instrument-test
                    
                
            
        
    

Using EA Async: A Practical Example

Incorporating EA Async into your code changes the way you handle asynchronous calls, making them look synchronous. Here’s a quick comparison:

Example with EA Async

import static com.ea.async.Async.await;
import static java.util.concurrent.CompletableFuture.completedFuture;

public class Store {
    public CompletableFuture buyItem(String itemTypeId, int cost) {
        if (!await(bank.decrement(cost))) {
            return completedFuture(false);
        }
        await(inventory.giveItem(itemTypeId));
        return completedFuture(true);
    }
}

Example without EA Async

import static java.util.concurrent.CompletableFuture.completedFuture;

public class Store {
    public CompletableFuture buyItem(String itemTypeId, int cost) {
        return bank.decrement(cost)
            .thenCompose(result -> {
                if (!result) {
                    return completedFuture(false);
                }
                return inventory.giveItem(itemTypeId).thenApply(res -> true);
            });
    }
}

Troubleshooting Common Issues

If you run into troubles while using EA Async, consider the following:

• Ensure you have the correct version of Java and EA Async library.
• Double-check JVM parameters and make sure you initialized the Async system.
• If you’re encountering issues with code instrumentation, verify your Maven or Gradle configurations.
• Refer to the GitHub Issues page for support.
