Why should we use "new" keyword to declare an instance variable? Why don't we use "new" keyword for creating a String?

For example, you've created a class named Abcd, and you use it in your main program (i.e., in the main method). We write it as : Abcd obj = new Abcd();

But for Strings, we write :

String a = "Bla Bla Bla ... ";

Why aren't we using : String a = new String();

??

String has special support. But I think you can explicitly call the string constructors. There is some slight difference in terms of how these are handled (see http://www.programcreek.com/2014/03/create-java-string-by-double-quotes-vs-by-constructor/ ), since java tries to optimize the use of strings.
