According to Kathy Sierra & Bert Bates' Book for Sun Java
Certification, in chapter 6th, page 246, portuguese version:
".........String s = "abc" // creates ONE String object and its
reference variable
String s = new String("abc"); // creates TWO String objects and a
reference variable.
//In this case, once we used the "new" keyword, the java language will
create a String Object in a memory, not in the pool, and
//variable "s" is its reference. Furthermore the literal string "abc"
will be inserted in a pool........ "
So, because in the second statemet we have TWO objects, certainly
it'll be using more memory.
