How to add new elements to an array?

Question

I have the following code:

String[] where;
where.append(ContactsContract.Contacts.HAS_PHONE_NUMBER + \"=1\");
where.append(ContactsContract.Contacts.IN_VISIB         


        

Answer 1

If you would like to store your data in simple array like this

String[] where = new String[10];

and you want to add some elements to it like numbers please us StringBuilder which is much more efficient than concatenating string.

StringBuilder phoneNumber = new StringBuilder();
phoneNumber.append("1");
phoneNumber.append("2");
where[0] = phoneNumber.toString();

This is much better method to build your string and store it into your 'where' array.
