Question:


How many String objects are created in the following snippet? Justify your answer.



String s1 = "Gujarat";

String s2 = new String("Gujarat");

String s3 = new String("Gujarat");

String s4 = "Gujarat";

Accepted Answer

Answer:


A total of 3 String objects are created.


Explanation:


Java stores string literals in a special memory area called the 
String Constant Pool (SCP).


Step-by-Step Analysis:

1. String s1 = "Gujarat";


    The string literal "Gujarat" is created in the String Constant Pool.
    1 object created.


2. String s2 = new String("Gujarat");


    The literal "Gujarat" already exists in SCP, so no new literal object is created.
    new String() creates a new object in heap memory.
    1 new object created.


3. String s3 = new String("Gujarat");


    The literal already exists in SCP.
    Again, new String() creates another new heap object.
    1 new object created.


4. String s4 = "Gujarat";


    The literal already exists in SCP.
    No new object is created.


Total Objects Created:


1 object in String Constant Pool
+
2 objects in Heap Memory
=
3 String Objects


Conclusion:


    String literals are reused from SCP ✅
    new String() always creates new heap objects ✅
    Total String objects created = 3
