How IoT, robotics, and AI are tackling one of the biggest problems of the century.

To get started, you must first create a class that implements the interface jpcap. To execute the class, you must make sure that the virtual machine can find the Jpcap native library. The output of executing the test class looks like this it’s shortened for space purposes: How Jpcap works Jpcap uses an event model to allow you to process packets.

If you call processPacketthen Jpcap will capture packets until either the timeout tutorisl in openDevice is exceeded or the maximum number of packets specified has been reached.

After choosing a device, you open it for listening by using the method Jpcap. The API provides the jpcap. Now that you have the Jpcap instance, you can start listening by calling either processPacket or loopPacket. The openDevice method returns a reference to a Jpcap object that will be used for capturing.
