#55 | submit() Vs execute() method | Java Interview

In this video, we explain the difference between submit() and execute() methods in the Java Executor framework — a very common Core Java & Multithreading interview question. 👨‍💻 What you’ll learn: • What execute() does and when to use it • What submit() does and why it’s more powerful • Runnable vs Callable support • How result handling works with Future • Key interview point: exception handling difference 🧠 Core difference: • execute() → runs a Runnable, returns nothing • submit() → runs Runnable/Callable, returns a Future 🚨 Interview gold: • execute() → exception is thrown immediately (prints to console) • submit() → exception is stored inside Future and appears only when get() is called 🎯 Interview-ready answer: execute() is used for fire-and-forget Runnable tasks, while submit() is used when you want to track task completion, get results, or handle exceptions properly using Future. Perfect for Java interviews, Executor framework, multithreading, and backend engineering prep. #Java #ExecutorService #SubmitVsExecute #Multithreading #Concurrency #CoreJava #Wipro #TCS #Accenture #Infosys #Cognizant #Capgemini #HCL
