Java OCA OCP Practice Question 3123

Question

Given this code snippet: 

public static Connection connectToDb() throws SQLException {
    String url = "jdbc:mysql://localhost:3306/";
    String database = "addressBook";
    String userName = "root";
    String password = "mysql123";
    // CONNECT_TO_DB
}

Which one of the following statements will you replace with the comment CONNECT_TO_DB to create a Connection object? 

a)return DatabaseManager.getConnection(url, database, userName, password);
b)return Connection.getConnection(url, database, userName, password);
c)return DriverManager.getConnection(url + database, userName, password);
d)return DatabaseDriver.getConnection(url + database, userName, password);



c)

Note

the getConnection() method in DriverManager takes three String arguments and returns a Connection:. 

Connection getConnection(String url, String user, String password)

hence, option c) is the correct answer.

the other three options will result in compiler errors.
