Concurrency and parallelism in Java
Concurrency and parallelism are two concepts in programming that deal with executing multiple tasks, but they differ in their approaches and purposes. Here’s a breakdown of each: Concurrency Concurrency is about dealing with multiple tasks at once but not necessarily executing them simultaneously. It allows a system to manage multiple tasks by interleaving their execution, giving the illusion that they are running in parallel. Key Characteristics: Task Interleaving: Multiple tasks make progress by being interleaved. Context Switching: The system switches between tasks frequently. Non-deterministic: The order of execution can vary. Resource Sharing: Tasks share resources like CPU, memory, etc. In this example, thread1 and thread2 run concurrently, and the output will interleave the print statements from both threads. public class ConcurrencyExample { public static void main(String[] args) { Thread thread1 = new Thread(() -> { for (int i = 0;
