To run this system, there are two executable classes in the "starter" package, which are "SenderStarter" class and "ReceiverStarter" class.

You should run the "SenderStarter" class first, then do not shut it down, run the "ReceiverStarter" class.

After that you will see the socket server and client is connected, which means the sender and receiver is connected.

In this system, some commands are provided for sender and receiver.

1. send file1, file2, file3, ...

   Only the sender can send files. You can use command send + space + filenames. For each of the filename, they should be seperated by ",". Moreover, the name should begin from "src/". You can just put the file into the folder "src/testFiles/testSendDir/" then copy the "path from the content root" of this file. An example has been given below.

   send src/testFiles/testSendDir/video1.mp4, src/testFiles/testSendDir/video2.mp4

   In this example, a task would be created, and in this task, those 4 files would be sent concurrently.

1. tasks

   Both of the sender and receiver can query the task list by using the tasks command. Then they will be shown with a list of their task, including the task id, task status, file number and finished file number.

   There are 3 types of status in total:

   1. "ongoing"
   2. "suspended"
   3. "finished"

2. query + space + task id

   Both of the sender and receiver can query the detailed information of a specific task by using this command. For example, query 1 command will show you the details about task 1, includes the status, finished bytes, progress and filename of each file transmission in this task.

3. suspend + space + task id

   Both of the sender and receiver can suspend a task in "onging" status. For example, suspend 1 would suspend the task 1, which means all the file transmissions in task 1 would be suspended.

4. resume + space + task id

   Both of the sender and receiver can resume a task in "suspended" status. For example, resume 1 would resume the task 1, which means all the file transmissions in task 1 would be resumed.

The downloaded files can be found in the directory of "src/testFiles/testReceiveDir/"
