Object Count..

[singhsn]

Can anybody help me to count how many objects are created during runtime in a java class as...

As in...

String s1="abc";
s1.concat(s1);
s1.replace('a','z');

How many String objects will be created(With explanation please...)

Any help on this will be highly appreciated.
Thanks

Hi.
Am not sure of your question. If you want to know the no of objects created by your class. You can have a counter variable in your constructor that can be just incremented . This will help to find out the no of objects actually created by the class.

String functions always return a new string object after manipulation. So here there are 3 object created.
String s1="abc"; One s1
s1.concat(s1); One return of this
s1.replace('a','z'); One return of this
