cem1: using super.method, obviously |
| 07:33 |
|
aditsu |
or just call the method directly if it's not oerridden :p |
| 07:33 |

|
cem1 |
after a hour search |
| 07:34 |
|
cem1 |
i found JLS didnt specify anything on it |
| 07:35 |
|
cem1 |
super doesnt reference any object |
| 07:35 |
|
cem1 |
while this does as per spec |
| 07:35 |
|
cem1 |
and i dont know anything beyond it, may be pulsar might know |
| 07:36 |
|
pulsar |
sorry, busy all day. |

cem1: I already answered your question, what are you asking pulsar for? |

your answer is not with respect to OP question |
| 07:59 |
|
cem1 |
OP asked why super doesnt point object rather super class |
| 08:06 |
|
aditsu |
the OP didn't ask me anything, you did |
| 08:06 |
|
aditsu |
and your question is very different |
| 08:09 |
|
aditsu |
btw, "super" is neither an object nor a class, it's a keyword |
| 08:09 |
|
aditsu |
and you can use it to access the super class's members |
| 08:24 |
|
cem1 |
k let take another keyword for example while,this |
| 08:24 |
|
cem1 |
SOP(while);//compilation error |
| 08:24 |
|
cem1 |
SOP(this);//works fine |
| 08:24 |
|
cem1 |
SOP(super);//compilation error |
| 08:29 |
|
aditsu |
cem1: "this" actually refers to the current object |
| 08:30 |
|
cem1 |
yes |
| 08:31 |
|
cem1 |
but super gives compilation error |
| 08:31 |
|
aditsu |
right, because "super" is not like that |
| 08:31 |
|
* cem1 |
seriously wants to learn english |
| 08:31 |
|
cem1 |
why aditsu |
| 08:32 |
|
aditsu |
English is a useful language to learn :) |
| 08:32 |
|
cem1 |
its very hard aditsu |
| 08:32 |
|
aditsu |
why? because that's how they designed it... you're supposed to use it like super.something, not by itself |
| 08:32 |
|
cem1 |
why ? |
| 08:33 |
|
cem1 |
how it does |
| 08:33 |
|
cem1 |
if its not object |
| 08:34 |
|
aditsu |
I don't know why they designed it like that, but that's how it works |
| 08:34 |
|
aditsu |
by the way, there's no notion of a "super" object, because the object is exactly the same |
| 08:35 |
|
aditsu |
it's just about accessing different methods |
| 08:35 |
|
* cem1 |
wants to know why they did this dilemma just read the JLS |
| 08:36 |
|
aditsu |
you can think of it as a tree with 2 rows of branches; "this" is the tree, if you call methods directly or via "this", you access the higher branches, if you use "super", you access the lower branches |
| 08:37 |
|
cem1 |
what is the past tense for read ? |
| 08:37 |
|
aditsu |
read (pronounced "red") |
| 08:41 |
|
aditsu |
you can also think of it another way... internally, class methods get the object passed as a parameter before all the normal method parameters (this stuff is more explicit in python); the object passed is always "this", but "super" chooses different methods to call |
