Java CSV file help

Input

• A file named bandwidth.csv, containing the Bandwidth information for a set of Network Interfaces. A Network Interface is identified by the couple [server, network interface name]
• A file named netbitrate.csv, containing the Network Bit Rate registered for the same set of Network Interfaces over a period. A Network Interface is identified by the couple [server, network interface name]

You are asked to develop a small procedure that, given the two CSV files, calculates the Network Bandwidth Utilization for every line in the netbitrate.csv file. The Network Bandwidth Utilization of an interface is calculated as the Network Bit Rate divided by its Bandwidth. The procedure needs to print the results on the standard output according to the following format:

Timestamp | Server | Network Interface | Network bit rate / Bandwidth

Hint: Please ensure that your solution considers floating point numbers

File: bandwidth.csv

Server, InterfaceName, Bandwidth

server1,eth0,10

server1,eth1,20

server2,eth0,10

File: netbitrate.csv

Timestamp, Server, InterfaceName, NetBitRate
