Concurrency Utilities in Java: Callable, ReentrantLock, and Synchronized Explained
Returning Values from Threads with Callable
The Callable interfcae allows threads to return computation results and throw checked exceptions. Unlike Runnable, it features a call() method designed for task execution. To retreive the result, wrap the Callable instance in a FutureTask and pass it to a Thread.
import java.util.concurrent.Callable;

Java Concurrency: Exploring Task Execution with Runnable, Future, FutureTask, and Thread States
Understanding Task Execution Interfaces in Java Concurrency
Java provides a robust set of interfaces and classes for managing concurrent tasks. At the core of asynchronous task execution are Runnable, Future, and FutureTask, each serving a distinct purpose in defining and managing computational units.
Key Concurrency Primitives: Runnable, Futu ...
