Threading: Lesson

Lesson 1 of 1

Introduction
So far, we have learned about threads and how they work in theory. Before we put it into practice, we should have a strong understanding of what kinds of problems multi-threaded programs are best s…

Extending the Thread Class
There are multiple ways to implement threading in Java. The first that we will try involves extending the Thread class. In Java, there is a built-in class that handles threads: java.lang.Thread. …

Implementing the Runnable Interface
In the previous exercise, you learned that you can convert a class to run as a thread by extending the Thread class. Java allows us to make classes threaded in another way as well, by implementing …

Supervising a Thread
So far, you have seen how to start threads with the .start() method and learned multiple ways to implement threads into sequential programs. Sometimes, you want to be able to see the status of th…

Waiting for Thread Completion
Another common scenario in multi-threaded programs is to wait for a thread to complete before proceeding in a path of execution. In other languages, this concept is called “awaiting” or “blocking…

Thread Synchronization
Another important scenario when working with multi-threaded programs is managing shared resources between threads. When you access the same data from two different threads, you may cause a _rac…

Communicating Between Threads
Previously, we learned how to block thread execution using .join(). However, this is only to block thread execution from the context where the thread was started. For example, if a thread was creat…
