The throws statement

We have to deal with SQLException because it is a checked exception, and the getConnection(), createStatement(), executeQuery(), and next() methods declare it in their throws clause. Here is an example:

Statement createStatement() throws SQLException;

This means that the method’s author warns the method’s users that it might throw such an exception, forcing them to either catch the exception or to declare it in the throws clause of their methods. In our preceding example, we have chosen to catch it using two try...catch statements. Alternatively, we can list the exception in the throws clause and, thus, remove the clutter by effectively pushing the burden of the exception handling onto the users of our method:

void throwsDemo() throws SQLException {

    Connection conn = 

      DriverManager.getConnection("url","user","pass");
