CHAPTER 16 Multi-threading

What is a thread? A thread executes a sequence of steps. The code in a method defines a series of actions. A thread executes the statements in a method sequentially. A thread is a sequence of execution. The statements in a method define a sequence of execution. A thread executes statements in a method one by one. Some of the statements being executed result in invocation of another method or constructor.

Every thread has a task, which it is executing. The task for a thread is defined in a method, which it is supposed to finish. What is required by a thread for executing the task (method)? In Java a thread uses a runtime stack to carry out its task. Initially the runtime stack is loaded with the method (frame is created) ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.
