而Loop变量赋值给Runnable

Question

为什么每个Runnable应该为每个设备分配不同的设备时打印相同的设备？

似乎每个Runnable都使用从while循环分配的最后一个设备。如何确保从循环中为每个Runnable分配一个设备？

Iterator<TaskCard> i = taskManager.getTaskCards().iterator();

while (i.hasNext()) {
    TaskCard taskCard = i.next();
    taskCard.updateTask();
    ReturnInterface<String> returnInterface = new TaskReturnIterface(taskManager, taskCard);
    Task task = taskCard.getTask();
    ProtocolInterface selectedProtocol = task.getDevice().getSelectedProtocol();
    selectedProtocol.setTask(task);
    selectedProtocol.setReturnInterface(returnInterface);

    SwingUtilities.invokeLater(new Runnable() {
        final ProtocolInterface mySelectedProtocol=selectedProtocol;
        @Override
        public void run() {  
            System.out.println("[Taskmanager.TaskReturnInterface.actionPerformed.RUN()]selectedProtocol device= " + mySelectedProtocol.getDevice());
        }
    });

}

下面是请求的协议接口代码。

public abstract class ProtocolInterface<N> implements Callable<ReturnInterface<N>>, Serializable{

protected DefaultDevice device;
protected String name = "";
protected Task task;
protected Date scheduledDate;
protected ReturnInterface<N> returnInterface;

final private CredentialInterface credential = new CredentialInterface() {
    private String user = "";
    private String password = "";
    private int port = 22;

    @Override
    public String getUser() {
        return user;
    }

    @Override
    public String getPassword() {
        return password;
    }

    @Override
    public int getPort() {
        return port;
    }

    @Override
    public void setUser(String s) {
        user = s;
    }

    @Override
    public void setPassword(String s) {
        password = s;
    }

    @Override
    public void setPort(int p) {
        port = p;
    }

    @Override
    public DefaultDevice getHost() {
        return device;
    }

    @Override
    public void setHost(DefaultDevice host) {
        System.out.println("[ProtocolInterface].CredentialInterface.setHost() host= "+host);
        device = host;
    }
};

boolean useIP = true;

public ProtocolInterface() {
}

public CredentialInterface getCredential() {
    return credential;
}

public ProtocolInterface(String name, DefaultDevice device) {
    this.name = name;
    this.device = device;
}

public DefaultDevice getDevice() {
    return device;
}

public ReturnInterface<N> getReturnInterface() {
    return returnInterface;
}

public void setReturnInterface(ReturnInterface<N> returnInterface) {
    this.returnInterface = returnInterface;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public Task getTask() {
    return task;
}

public void setTask(Task task) {
    this.task = task;
}

public Date getScheduledDate() {
    return scheduledDate;
}

public void setScheduledDate(Date scheduledDate) {
    this.scheduledDate = scheduledDate;
}

public abstract Icon getIcon();

public abstract CredentialForm_Interface getCredentialForm();


@Override
public int hashCode() {
    int hash = 7;
    hash = 47 * hash + Objects.hashCode(this.device);
    hash = 47 * hash + Objects.hashCode(this.name);
    return hash;
}

@Override
public boolean equals(Object obj) {
    if (this == obj) {
        return true;
    }
    if (obj == null) {
        return false;
    }
    if (getClass() != obj.getClass()) {
        return false;
    }
    final ProtocolInterface<?> other = (ProtocolInterface<?>) obj;
    if (this.useIP != other.useIP) {
        return false;
    }
    if (!Objects.equals(this.name, other.name)) {
        return false;
    }
    if (!Objects.equals(this.device, other.device)) {
        return false;
    }
    if (!Objects.equals(this.credential, other.credential)) {
        return false;
    }
    return true;
}



@Override
public String toString() {
    return name;
}
