Result query more than one record?

[Macamba .]

In my Java application I query, and get back one record. What if a new query gets back more records, like a table?

For instance:

SELECT `project`,`activity, 
        SEC_TO_TIME(SUM( TIME_TO_SEC(`worked_time`)))
FROM `projects` 
WHERE `day` <= "2017-04-09" # Sunday 
  AND `day` >= "2017-04-03" # Monday, start week
  AND `active` = 1 
GROUP BY `project`, `activity`;

This will result in:

project 		Activity 	worked_time 	
Flubber			Specific	03:00:00
Promotion activities 	01 Search	01:15:00
Promotion activities 	Travel		03:00:00
UB Development 		Development 	05:00:00
Work and information 	Travel		01:30:00
Work and information 	Symposium 	04:30:00

How do I read this result from the database, and display it into my application?
