You need to load the class driver before getting a connection:

Class.forName("com.mysql.jdbc.Driver").newInstance();

Here is an example.

and the working code:

Connection conn = null;
        try {
            Class.forName("com.mysql.jdbc.Driver").newInstance();
            conn = DriverManager.getConnection("jdbc:mysql://localhost/sampledb?" + "user=root&password=14701");
        } catch (SQLException ex) {
            System.out.println("SQLException: " + ex.getMessage());
            System.out.println("SQLState: " + ex.getSQLState());
            System.out.println("VendorError: " + ex.getErrorCode());
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (conn != null) {
                try {
                    conn.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        }

Answer 2

You don't have the driver/connector in the classpath. Go to https://dev.mysql.com/downloads/connector/j/8.0.html and download the jar file and put in your classpath.

Something like this:

java -cp .;mysql-connector-java-xx-xx.jar com.xx.xx.yourApp

you also need to load the driver like this:

Class.forName("com.mysql.jdbc.Driver");
