How to deal with multiple threads in one class?

Question

Threads are often designed in two ways (see java tutorials): either by extending the Thread class or by implementing the Runnable class. Either way, you need to specify what wil

Answer 1

Many people have already suggested good methods of how to do this using several classes. Since you seem to prefer a way which doesn't require multiple classes, you might also want to consider using the constructor to give information about which resource to fetch:

public class OnlineResourceAdapter implements Runnable
{
    private string resourceType;

    public OnlineResourceAdapter(string resourceType)
    {
        this.resourceType = resourceType;
    }

    public void run() {
        if (resourceType.equals("A") {
            getInformationOfTypeA();
        } else {
            // etc..
        }
    }

    public void getInformationOfTypeA(){
        //get information of type A
    }

    public void getInformationOfTypeB(){
        //get information of type B
    }
}

Usage:

(new Thread(new OnlineResourceAdapter("A"))).start();
