This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Hi, Null character is the default value of a char (which is a primitive type). The excat value is '\u0000' . A pipe is a way to transfer datas, which works like petrol pipe-line.
