Question regarding inner class

[Ja vardhan]

In K&B book we have the question:

Which constructs an anonymous inner class instance?

Runnable r = new Runnable() {public void run{}};

System.out.println(new Runnable() {public void run() { }});

They have given the answer is second one.

Please expalin how come?

Thanks.

well I think both constructs are ok cos these two are all ways to create and anonymous class

Hi Vardhan,

The 2nd answer is correct.Anonymous class is always declared and instantiated on the fly.The 1st option is that of a normal object creation.

Mambe/Nikhil Thanks for your replies.

If we kept aside the ananymous class concept, is the first one right or wrong ?

Thanks.

Runnable r = new Runnable() {public void run{}};
>>>run{} isn't ok for a method declaration=>run(){} is the way it must

System.out.println(new Runnable() {public void run() { }});
>>>this one is the right one..., its just good looking for the brackets and ';' and () lol...
:-)

i forgot :
the first one is ok, only the synthax is wrong...
Runnable r = new Runnable() {public void run>>>{}<<<};

Runnable r = new Runnable() {public void run>>>()<<<};
this is allowed...;-)

Reper,

i forgot :
the first one is ok, only the synthax is wrong...
Runnable r = new Runnable() {public void run>>>{}<<<};

Runnable r = new Runnable() {public void run>>>()<<<};
this is allowed...;-)

Do you mean to say first one is right or wrong?

Thanks.

[Arno Reper]

like they write it, its wrong...they omitted the ()

ups i forget a thing
Runnable r = new Runnable() {public void run(){}};

do you understand what i mean?
