I added two of my classes. my question is, after i added new engineers to the ArrayList, how can choose a specific Engineer and "edit" his ID or Salary (through the "menu" using Scanner)? then how can i remove a specific Engineer from the ArrayList? hope somebody can understand my code in order to help. thanks.
package logic;
