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

Two anonymous inner classes, like Thorbjørn Ravn Andersen suggested vaguely above, works. Here is a code example:

public class OnlineResourceAdapter {

    public final Runnable typeA;
    public final Runnable typeB;

    public OnlineResourceAdapter() {
        typeA = new Runnable() {
            public void run() {
                OnlineResourceAdapter.this.getInformationOfTypeA();
            }
        };
        typeB = new Runnable() {
            public void run() {
                OnlineResourceAdapter.this.getInformationOfTypeB();
                // one can use a non-final typed variable
                // to store, which then<1>
            }
        };
    }

    public static void main(String args[]) {
        OnlineResourceAdapter x = new OnlineResourceAdapter();
        new Thread(x.typeA).start(); // start A
        new Thread(x.typeB).start(); // start B
        // <1>can be accessed here.
    }

    public void getInformationOfTypeA(){
        // get information of type A
        // return the data or directly store in OnlineResourceAdapter.
    }

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

}

Edit: Yes, you're proposed way is a good way. You can even make the methods static. You can use "OnlineResourceAdapter.this." to access other variables to store results in.
