Hi,
I am no where find this question in above link..please provide me the answer

there can be serious problems with the use of HashMap and HashSet (and similar structures) if the hashCode() is calculated from the value of the member variables (which is typical) if they are allowed to change.



Thanks Mike and Pat...

Pat i didn't get the HashMap and Set usage...
Some where i read as "make good Map keys and Set elements (these objects must not change state while in the collection)
"
Please explain me in detail....

if you don't want the behavior of the object to be changed by anyone. String is made immutable in order to standardize its behavior.



Thnaks for the reply...
