Java Multithreading and Parallelism Practice Exam
About Java Multithreading and Parallelism Exam
Multithreading is an advanced programming technique that allows a program to run multiple tasks at the same time. It improves performance, speeds up processes, and makes applications more efficient. This course focuses on teaching multithreading concepts from scratch using Java, with plenty of hands-on examples, real-world applications, and projects. You’ll also learn how multithreading connects with popular frameworks like Spring Boot, RxJava, and JavaFX.
