Training Android: Day 03 and 04

Thai studied faster than my expectation. At 3rd and 4th day, I give him some oop presentations from mr. nmhuy about polymorphism and inheritance.

Every time he got problem or something went wrong, we work remotely through TeamViewer and Skype. Exercises was assigned through Trello cards.

  • polymorphism in oop
  • inheritance in oop
  • exercises about them
