Program to capture data and address connected by a certain program

I need to capture the remote addresses that a program 开发者_如何学JAVAconnects to and the data that it sends and receives on Win 7. any suggestion for the program I can choose?

Use Wireshark (which includes the libpcap packet capture library). Wireshark provides a packet sniffer GUI and a number of analysis tools that will summarize traffic by endpoint(s), protocols, and other characteristics. http://www.wireshark.org/
