Как заполнить базу данных sqlite листом объектов?

Я работаю с файлом преобразую содержимое лист объектов, теперь мне надо добавить их в базу данных. Всего 6 таблиц в базе данных.

public class ReadFileActivity extends AppCompatActivity implements View.OnClickListener{
    Button read;
    private static ArrayList<Errors> errors = new ArrayList<>();

    // Константы для элементов
    private static final String BackBrakePressureEmergency = "BackBrakePressureEmergency";
    private static final String CloggedSteeringFilters = "CloggedSteeringFilters";
    private static final String CloggedSteeringFiltersGS = "CloggedSteeringFiltersGS";
    private static final String EmergencyOil = "EmergencyOil";
    private static final String EmergencyOilLevelGS = "EmergencyOilLevelGS";
    private static final String FontBrakePressureEmergency = "FontBrakePressureEmergency";
    SQLiteDatabase db = getBaseContext().openOrCreateDatabase("MyDiplom.db", MODE_PRIVATE, null);
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_read_file);
       SQLiteDatabase db = getBaseContext().openOrCreateDatabase("MyDiplom.db", MODE_PRIVATE, null);
        read = (Button) findViewById(R.id.buttonReadAndSwap);
        read.setOnClickListener(this);
    }

    @RequiresApi(api = Build.VERSION_CODES.N)
    @Override

        switch (R.id.buttonReadAndSwap){
            case R.id.buttonReadAndSwap:
                try {

    private void addDataToDatabase(){
      // List<Errors> errors = new ArrayList<>();
      // errors.add(new BackBrakePressureEmergency(4,"startDate","endDate",4));
      // errors.add(new BackBrakePressureEmergency(4,"startDate","endDate",4));

      //             er.getDuration());
      // }
      // db.close();

    }

}

Как мне теперь добавить в базу?

package Models;

public abstract class Errors {
    //public String turnover;
    //public String startDate;
    private String startDate;
    private String endDate;
    private int duration;

    public Errors(String startDate,String endDate,int duration) {
        this.startDate=startDate;
        this.endDate=endDate;
        this.duration=duration;
    }

    public String getStartDate() {
        return startDate;
    }

    public void setStartDate(String startDate) {
        this.startDate = startDate;
    }

    public String getEndDate() {
        return endDate;
    }

    public void setEndDate(String endDate) {
        this.endDate = endDate;
    }

    public int getDuration() {
        return duration;
    }

    public void setDuration(int duration) {
        this.duration = duration;
    }
}
