How many objects created in the following:
String str1;
String strExample = new String("Hi");

only 1.
str1 is just a string ref variable and not an object.

Hmmm..........
Shouldn't it be 3 objects?
str1 will be given a default value as null, so there is a null object created.
strExample has a String object "Hi" created and passed to the new constructor to created another String object that assigned to strExample later. So two object has been created.
I just can't sure whether the null one should be counted or not.

Hi,
There are two String objects created at line 2.The null string object will not be a new object so there are two string objects created on a heap.

I believe null is NOT an object. It is merely a type.
