@Deadpool Please excuse me but I don't speak [newspeak](https://en.wikipedia.org/wiki/Newspeak) Does _SCP_ mean "String Constant Pool"? – Abra Jan 03 '20 at 15:57

Total 3 objects will be created.
Line 1 : Object will be created in string pool,
Line 2 : Object will be created in Heap,
Line 3 : Object will be created in Heap.
Reason is :
a) By string literal : Java String literal is created by using double quotes like in line 1. It is always created in String pool,
b) By new keyword : Java String is created by using a keyword “new” like in line 2 and 3. It is always created in Heap memory.
