#54 | What is the Executor framework ? | Java Interview

In this video, we explain what the Executor Framework is and why it is preferred over manual thread creation — a must-know Core Java & Multithreading interview question. 👨‍💻 What you’ll learn: • What the Executor Framework does • Why creating threads manually is inefficient • How thread pools improve performance • How Executor manages threads for you • Support for Runnable, Callable, and Future 🧠 Key idea: You submit tasks, not threads — the Executor handles thread creation, reuse, and scheduling. 📌 Why Executor is preferred: • Reuses threads (thread pooling) • Better performance and scalability • Controls resource usage • Easy task management and shutdown • Supports returning results via Callable + Future 🎯 Interview-ready answer: The Executor Framework provides a high-level way to execute tasks using thread pools. It is preferred over manual thread creation because it improves performance, reduces overhead, provides better control over threads, and supports task scheduling and result handling. Perfect for Java interviews, multithreading, backend preparation, and real-world concurrency concepts. #Java #ExecutorFramework #Multithreading #Concurrency #CoreJava #JavaInterview #Wipro #TCS #Accenture #Infosys #Cognizant #Capgemini #HCL #BackendEngineering
