刚开始学java
我有以下数据集
Date first seen Duration Proto Source IP Addr:Port Destination IP Addr:Port Packets Bytes Flows
2013-03-03 23:54:46.574 8.000 UDP 108.169.77.76:12345 -> 108.169.0.112:53 5 325 1
2013-03-03 23:59:51.984 0.000 UDP 100.253.69.196:62458 -> 100.256.234.129:1947 1 68 1
2013-03-03 23:59:52.048 0.000 UDP 108.450.45.35:123124 -> 108.123.0.987:9101 2 1686 1
我想用Java编写一个程序来只获取一列源IP地址和一列目标IP地址?有人可以告诉我如何做到这一点的示例代码吗?
