What Are Processes and Threads
This section describes processes of multi-tasking operating systems and threads of multi-threading applications. Java is a programming language that allows you write multi-threading applications.
What is a thread? What is a process? Answers are in the following explanations:
There are 3 levels of executions of computer instructions on a computer system:
A good example of multi-threading programs are computer games that simulate real time activities of multiple human characters and/or moving objects.
Under the Java architecture, the Java virtual machine (JVM) will provide all the help you need to create and manage multiple threads in your Java applications. Read subsequent sections for tutorial examples.
