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 31.3.-4.4.2025, a practical knowledge test will be held, where you will create code according to the assignment (programming test) at the computer in the classroom.

Themes:

• Logging, exception logging, efective logging
• Lombok
• java record
• enum, switch, pattern mathing
• Functionla Interfaces
• JPA entity a JPA entity with relation
• CriteriaQuery

Semester Project 10-25

The semester project must be submitted via the Kelvin or Edison system (to be specified) and defended individually during the exam period; dates will be announced. Project topics will involve creating a REST API server for storing data from a game or from a GUI developed 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 a REST API, and a front end using any web technology or JavaFX.

Detailed description here

The deadline for submission is June 21, 2026, or prior to the project defense.

Part-time study

The requirements for part-time students are the same. The only difference is that they do not have graded tutorials, so the point distribution for the remaining assignments is different.

    Homework assignments (0–20) – there are 5 homework assignments, each worth 4 points
    Practical knowledge test (10–25) – will take place on April 25, 2025, at 7:15 a.m. during the tutorial
    Semester project (10–30)
    Midterm exam (10–25)
