Course Java 1.0.

Object-oriented programming is a way of writing programmes based on the interaction of objects. It is the most popular and widely used way of developing programmes. It is impossible to imagine a world without objects; they are an integral part of it. The Java programming language allows you to develop programmes using the abstraction of objects (their simplified version) and their interaction mechanisms.

In programming languages, variables are used to access and adjust memory and are used to store intermediate results when processing data. As in mathematics, operators and expressions form the operations that are performed when processing data.

Classes and objects are key elements in object-oriented programming when using a programming language like Java. Using classes (special constructs of the Java programming language), the programmer describes what objects are, what properties they have, and how they interact during program execution. During program execution, objects are created based on classes that are stored in the RAM of the selected program.

It’s not enough to know how to code; to work in a team you need to be able to write code that can be easily read by other programmers. This is what is known as clean code – code that is designed for humans, not computers.

Programming often involves processing large amounts of data. In such cases, special data structures such as lists, clusters and maps help the programmer. Without them, it is impossible to imagine any programme written in Java.

Encapsulation, inheritance, polymorphism are the basic principles of object-oriented programming. When these principles are applied correctly, it is possible to solve problems, create complex structures, and write high-quality code that will last a long time.

Nowadays, it is impossible to write a code without checking it automatically. jUnit is one of the most popular libraries for programming tests written in Java.

The Stream API and Lambda expressions introduced in Java 8 made it easier to write software code. Modern projects, used in everyday life, successfully introduced innovations.

Most of our students are interested in job opportunities. We are addressing key questions that could be raised in job interviews. We prepare students for job interviews. We share experiences.
