as I mentioned by using java so I need to create a program which include these steps $1.$ Create a computer program using Java to implement the network monitoring, $2.$ Create simple GUI, to show the results, the GUI had to have Tables Charts, $3.$ The system should be implemented on real network, $($you machines or university networks$)4.$ Create a Test Cases scenario, and test documentation and then test the system using stating and dynamic testing. But most importantly using new technologies to implement easier with JAVA, lastly the programs interface will be similar to wireshark but more basic one ofc.
