    well for a start `std` is an array of `Tech` not `String` and they have not been instantiated (only defined) - maybe `std[i] = new Tech(name);` – Scary Wombat Aug 18 '17 at 06:44

    Take care of the Java naming convention. variable names should start with lowercase character – Jens Aug 18 '17 at 06:45
