Please click the following link and see the image of the rfid reader which I brought recently

And I need help to assemble this with Arduino mega 2560. How to wire this RFID reader with Arduino mega 2560, and then how to get the input (swiped RFID tag number) to the Java program?
My Arduino mega 2560 is connected to my pc via com5.
The description of the HZ-1050 EM Module ID Card Reader states:
By taking a short look at your picture, I would say you connect the module to a 3.3V or 5V source - best would be the source of your Arduino - and connect the TXD output to one of the UART inputs of your Arduino board (you should have 4 ports and only one is occupied by the PC). Check the voltage of your UART levels to have either both working at 3.3V or both at 5V. In your program, forward the byte stream (coming from the reader module) to your host PC (via COM5).
