Number of objects created in StringBuilder ?

I know -- if it had been string here like ::
String s = new String("abc");
2 objects are created.

But, how many objects are created when we say --

StringBuilder sb = new Stringbuilder("abc");

Thanks.

Hallo,

When using StringBuffer, the case is one-by-one, meaning, one object and one reference.

So, when we say:



There will be this one object on the heap with stringBuffer referring to it.

Good luck ...

Sorry i forgot to say that StringBuffers don't go to the String constant pool.

 
It is sorta covered in the JavaRanch Style Guide.
