U can instantiate intrfaces provided...

Posted by Siraj on September 26, 2000 at 7:22 AM

Hi shahul,
You can do sth like implementing interfaces in your code only when you are using anonymous classes, where you can use the syntax like this.
new someInterface(){
void doIt(){
What you are really doing here is just implementing the interface. But since it is an anonymous class , the syntax is like that, which might have confused you. Otherwise, you are not permitted to do that directly even in JDK 1.2.
Hope that u'r doubt is cleared. If not, get back to me.

> Runnable run = new Runnable() works? I used to believe that interfaces where implicitly abstract and therefore could not be instantiated; only implemented. Is Object somehow involved in this???
