Thanks Andreas but I am running out of time that is why I could get from
.NET since I needed only string.
Only last week I ventured into bitcoinj api and due to lack of time, I
couldn't go deep into code.
I have looked into the bitcoin core code and the string
"04ffff001d0104455468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f72206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73"
is already hardcoded.
NetworkParameters.java
Method: private static Block createGenesis(NetworkParameters n)
// A script containing the difficulty bits and the following message:
//
// "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks"
byte[] bytes = Utils.HEX.decode
("04ffff001d0104455468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f72206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73");
