String reference

The following is from http://www.jchq.net/essentials/d0e1214.htm:
----------------------------------------------------------------------
Note that if you construct two Strings with the same String literal, without using the new keyword, e.g.
String a = "Hello"
String b = "Hello"
, then Java creates only one String object, so a==b evaluates as true.
------------------------------------------------------------------------
I think a==b should evaluate as false since they are pointing to two different String object.

String literals are stored in the String pool without duplicates so they do point to the same String.
Compare this:
String a = "JAVA";
String b = "JAVA";
System.out.println(a == b);
to this:
String a = new String("JAVA");
String b = new String("JAVA");
System.out.println(a == b);
