contentValues.clear()

Question

Hi,
Please tell me, why <clear()> is used in the code bellow? Is it realy needed?

ContentValues contentValues = new ContentValues();
db.execSQL("create table position ("
+ "id integer primary key, "
+ "name text, "
+ "salary integer"
+ ");");
for(int i = 0; i < position_id.length; i++) {
contentValues.clear(); // ??
contentValues.put("id", position_id[i]);
contentValues.put("name", position_name[i]);
contentValues.put("salary", position_salary[i]);
db.insert("position", null, contentValues);

Answer 1

Clear() is a method of ContentValues which possibly extends Arraylist I dont think this is the full code so its difficut say but if it is then clear(); removes all elements from the list.
