Android Studio Change Array Value

Hi i would like to know if there is a method that takes an element of my array and deleting it depending the answer of the user.For example in my code i have an array of countries

Solution 1:

Use ArrayList to delete dynamic index value

ArrayList<String> customlist = new ArrayList<String>();
customlist.addAll(country);
customlist.remove(randome);


String []copycountry = new String[customlist.size()];
customlist.toArray(copycountry);

Solution 2:

It's better to use List when array size is not fixed.

  int randome=0;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final Button no = (Button) findViewById(R.id.No);
    final Button yes=(Button) findViewById(R.id.Yes);
    final TextView tvMessage=(TextView) findViewById(R.id.tvMessage);

    final ArrayList<String> country = new ArrayList<>();
    country.add("greece");
    country.add("germany");
    country.add("america");
    country.add("serbia");
    country.add("france");
    country.add("england");
    country.add("cyprus");
    country.add("japan");
    country.add("russia");
    country.add("china");
    no.setsetOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if (randome>=0 && randome<country.size()){
                country.remove(randome);
            }
        }
    });
    yes.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Random rand = new Random();
            randome = rand.nextInt(country.size());
            tvMessage.setText(country.get(randome));

        }
    });
}
