How to create string object at Heap and String constant pool using one statement in Java

We can create string object at Heap via below statement.
String str = new String("ABC") ; By executing this statement "ABC" will go in Heap but not in string constant pool.
Again, we can create the same object in string constant pool via below statement.

String str = "ABC" ; By executing this statement "ABC " will go in string constant pool but not in Heap.
Now , If we want to create object "ABC" to be created on both String constant pool and Heap we can use the below statement .
String str = new String("ABC").intern() ;
BY executing above statement object will be created both at String constant pool and Heap.
So , executing String str = "ABC" ; after above statement will never create object as it always refer the object in string constant pool.
