Answer 1

I'd do this a little differently, avoiding an intermediate text file. Instead,

• Use ProcessBuilder, which "can be invoked repeatedly from the same instance." You can read the output as shown here and parse it into a suitable data structure, e.g. List>.

  ProcessBuilder pb = new ProcessBuilder("ps -ef");
  

• Start a javax.swing.Timer having a three second period; invoke pb.start() in the timer's listener.

• When parsing concludes, fireTableDataChanged() in your AbstractTableModel, shown here.

Presto, your table updates with the latest result every three seconds.
