History homework help. It looks like it’s a lot but it’s not. It’s basically a FTP Program that download and upload showing the status. And also ability to change directory. The only java class that needs to be updated are: FTPGui3, PutJob, GetJob, JobTableModel, and ExecutorTransferEngine. The other classes you don’t need to configured. Please read Project 3 and Project 4 requirements. On Project 3, I need help on displaying the progress status of the job. On Project 4, the ExecutorTransferEngine needs a complete redesign since the codes in there are single thread transfer engine. I have an issue on the JComboBox on both local and remote. After reading the requirement carefully, the combo box needs to be refresh to the selected directory. The project is using the ftp4j library which can be found at (ftp4j-1.7.2.jar)http://www.sauronsoftware.it/projects/ftp4j/download.phpI would like to have this assignment completed in 5 hours if possible. Thank you very muchAttachment 1Attachment 2Attachment 3Attachment 4Attachment 5Attachment 6Attachment 7Attachment 8Attachment 9Attachment 10
