Given a SQLiteDatabase object named db and a variable named taskID that contains a valid ID for a task, what does the following code do?

String where = "_id = ?";
String[] whereArgs = { Integer.toString(taskID) }; this.openReadableDB();
Cursor cursor = ("task", null, where, whereArgs, null, null, null);

Answer 1

The given code is used to query a SQLiteDatabase object named db for a specific task with a given taskID.

Step-by-step explanation:

The given code is used to query a SQLiteDatabase object named db for a specific task with a given taskID.

The code creates a WHERE clause with the condition '_id = ?' and a WHERE argument array containing the taskID value.

It then opens a readable database, executes the query with the 'task' table, the WHERE clause, and the WHERE argument array, and returns a Cursor object containing the result set.
