        preparedStatement = conn.prepareStatement(query);

        preparedStatement.setString(1, league);
        ResultSet rs = preparedStatement.executeQuery();

I need to save the retrieved season into a variable how can I do this ?

Answer 1

You can call rs.next() to move the cursor for the ResultSet to the next row. That method will return a boolean indicating whether or not there actually is a next row, so you can use either an if statement or a while loop to retrieve the first or all of the rows returned.

// only ever retrieve the value from the first returned row, even if there are multiple
String season = null;
if(rs.next())
    season = rs.getString(1);

OR

// retrieve the values of all returned rows and store them in a list
List<String> seasons = new ArrayList<String>();
while(rs.next())
    seasons.add(rs.getString(1));
