I currently want to create my first project app, that will help user to start an adventure in a gym. The code that I provided is for set by given earlier value the spinners with body parts. I've got some methods that I think can be shorter, but I don't know how I can make it. First, I'll explain how it all should work. Let's take a closer look at every method that I have to make everything work.

The first one called getMondayBodyParts. It has to search in a database for three Strings with a value choose by us body parts from previous layout (to make it more clear - in a previous layout we just have a three Spinners where we can select which body parts we want to train in Monday).

public void getMondayBodyParts(){

    Cursor cursor = db.getMondaySplitPlan();

    while (cursor.moveToNext()){

        mondayFirstBodyPartFirstExerciseString = cursor.getString(1);

        mondaySecondBodyPartFirstExerciseString = cursor.getString(2);

        mondayThirdBodyPartFirstExerciseString = cursor.getString(3);

    }

}

The second method is populateSpinners, which just populates spinners which will display exercises for specified by us body parts.

public List<String> populateSpinners(String string) {

    List<String> data = new ArrayList<>();

    switch (string) {

        case "shoulders": {

            data = db.getShouldersData();

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

            break;

        }

        case "chest": {

            data = db.getChestData();

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

            break;

        }

        case "back": {

            data = db.getBackData();

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

            break;

        }

        case "biceps": {

            data = db.getBicepsData();

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

            break;

        }

        case "triceps": {

            data = db.getTricepsData();

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

            break;

        }

        case "forearm": {

            data = db.getForearmData();

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

            break;

        }

        case "stomach": {

            data = db.getAbsData();

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

            break;

        }

        case "legs": {

            data = db.getLegsData();

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

            break;

        }

        case "calf": {

            data = db.getCalfData();

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

            break;

        }



    }

    return data;

}

The third method that I want to change is called setMondayFirstBodyPartExercises. I don't know how exactly it should look like, but I want to just paste three Strings which will populate spinners with specified data. For example, let's assume that we want to train like legs, biceps, triceps (then this method will sent value from those Strings to populateSpinners and it will show exercises. For now, I've created three methods which practically look the same with one difference between them.

public void setMondayFirstBodyPartExercises(String bodyPartString, Spinner first, Spinner second, Spinner third) {

    List<String> data = populateSpinners(bodyPartString);

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    first.setAdapter(adapter);

    second.setAdapter(adapter);

    third.setAdapter(adapter);

}



public void setMondaySecondBodyPartExercises(String bodyPartString, Spinner first, Spinner second, Spinner third) {

    List<String> data = populateSpinners(bodyPartString);

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    first.setAdapter(adapter);

    second.setAdapter(adapter);

    third.setAdapter(adapter);

}



public void setMondayThirdBodyPartExercises(String bodyPartString, Spinner first, Spinner second, Spinner third) {

    List<String> data = populateSpinners(bodyPartString);

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data);

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    first.setAdapter(adapter);

    second.setAdapter(adapter);

    third.setAdapter(adapter);

}

I want to change this line:

List<String> data = populateSpinners(bodyPartString);

I think it will be better when I call this method three times, and everything will be populated just by one method, instead of three different ones.
