Course Organisation and Conditions of Graduation

Scored assignments on exercises - minimum 10 out of 25

Starting with the first exercise (week of 2/17 - 2/21/2025), exercises will be scored. Thus, the exercises will always require a problem to be solved, for which points will be assigned similarly to Java I. There are 13 weeks in the semester, the last one will have a credit test, one exercise will be dropped due to Easter and Sports Day, (Thursday's two exercises will be dropped due to a public holiday) and one exercise will have a practical knowledge test. So 9-10 exercises, each of them will be possible to get 3 points. Only 25 points can be recorded, but the higher number will solve any normal frequency of absences due to illness and will not have to deal with substitute exercises. In the event of prolonged sickness, everything will be dealt with on an individual basis.

Homework minimum 0 points out of 10

Each scored exercise corresponds to one homework assignment for which 1 point may be earned. The homework is for practice and cannot be accurately verified, so only a limited number of points are awarded.

Practical knowledge test with a minimum of 7 points out of 15

During the week of April 17 - 11, 2025, a practical knowledge test will be held, where you will create code according to the assignment (programming test) at the computer in the classroom.

Semester project 10-25

The semester project will be submitted in kelvin or edison (to be determined) and defended individually during the exam period, dates to be announced. Project topics will be the creation of a REST API server to store data from a game, or from a GUI created in other courses.

Credit Test 10-25

The credit test will take place in the last week of the semester and will test theoretical knowledge in the form of an electronic test in the LMS.

Semester project

Create a web application (back end in Java - Spring/Quarkus) with REST interface, front end in any web technology or JavaFX.

Use the project from last semester (game) and focus on data storage. Store the data using REST API (Swagger/Open Api generator can be used). It is also possible to use the project in other courses where the goal is to create a web application and serve the solution with the project to the Java2 course.

The application will use a database through JPA. A minimum of 3 entities with bindings between them will be used. At least one binding will be at least 1:N.
