Creating Threads

There are two ways to create a Thread object. Listing 11.1 shows the approach you should use most often (from an object-oriented design perspective).

Creating Threads with Runnable Objects: Code Example

You can create a Thread in two ways. You may create a Thread using an instance of a class that implements the Runnable interface. This is the best choice generally from an object-oriented design perspective. Or, you can subclass the Thread class to make an object that inherits from Thread. The former, generally superior approach is shown in Listing 11.1.
