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.
