Welcome to my small zoo. Here I only keep different kind of birds. I have some big paCkAGEs, sorry CAGEs, over here in which I keep birds in pairs. i.e., a cage contains birds of different classes and one pair for each class in a cage. If a pair gives birth to babies, I normally transfer the babies to another cage.
I had been noticed a peculear behaviour in each family. Who in my zoo is allowed to touch (and love ) the lady in a family is restricted. Some are allowed to touch by any bird and some are by only by the member of her family (her husband). Noticing such an interesting thing I kept attatching a label to all the females. The labels went like public, private, protected, default (for default I usually attatch a blank label) and so.
One day suddenly I heard a male bird talking to its wife. It was trying to explain about the meaning of the labels. It was saying:


O my dearling, listen to me, I've got the trick!
If everybody loves you then you are public.
If it's not everybody but all in this cage,
Then you are said to be default to our paCkAGE;
If also our child kisses your head,
You are then nothing but known as protected.
If everybody but me only hate,
Label on you then will be private.
O dearling, why are you showing you rage?
Lets go to sleep in our sweet-home-cage

Hi,
I remember when I was studying OOP using Java course, some of my class fellows were really confused about who can access private & public members & who can not!.There was a loud debate/discussion was going b/w them.I was luckily the only SCJP in my class.Therefore they came to me and ask,
"What is this hell?? ...who will access private and public and who will not??...". I just stuck and thought how I will explain to these firing guys

I suddenly asked them:
"Who can touch your private members of body?
They said we ourself offcourse!.
Then i asked:
Who can touch your public members like hand?
They said, every one offcourse!."
After this they never forget who can access and who cannot access private and public members.

Bye,
Viki.
NOTE:I gave this example b/c they are my friends.But i think i couldn't if i were on the stage of a class
So be cautioned Kathy and Bert to use this in ur coming book

Hi,

Prime minister Can Never Be A Defeatist
Defeatist Is Not The Property Of A Programmer
But Programmer Can Be A Pugilist!
For remembering,
Access modifier sequence:
private--->default---->protected---->public

Hope it helps..
Bye,
Viki.

May be keeping Multiple husbands are allowed
Well, for interface, as it means a contract.So a good remembering phrase for multiple interface implementation may be:
Having Multiple Contracts Signed Is Allowed
Having Multiple Interface Implemented Is
Allowed!
.

Bye,
Viki.

Ok folks, time's up, pencils down !
Thank you all for your wonderful Java Memory Aids ! Now Kathy and I have to print out all of these entries, retire to the soundproof judge's room, and go into ponderous deliberations.
When we emerge (sometime later today), we will announce our three winners!
Thanks again ! we're blown away!
-Bert and Kathy

Um, this is an old old thread. Please try to refrain from resurrecting old threads. It really confuses people, and most of the time the ones that had originally posted aren't around to respond.

Regarding class accessibility modifiers I remember the following sentence which is literally very true :

Public can not be Protected by the Default police but by Private security agencies.

When a postfix operator is used as part of an expression, the value of the variable in the expression is used before incrementing it. (That's how Java works!)
