Java Basics - free course from Hexlet, training 37 hours, Date: December 1, 2023.
Miscellaneous / / December 04, 2023
Included in the course
- 29 lessons (video and/or text)
- 35 exercises in the simulator
- 111 verification tests
- Additional materials
- Help in "Discussions"
What will you learn
- Create simple programs using basic language constructs (conditions, loops, methods, etc.)
- Separate code into methods for reuse
- Correctly analyze errors in code and use debug printing when searching for them
You'll become familiar with data types in Java and learn more about methods, conditions, loops, and other basic language constructs. As a result, you will learn to write simple programs, use and define methods, find and analyze errors in the code. The knowledge from this course will help you gain a basic understanding of the Java language, its principles and features. This course is suitable for both those new to programming and those learning a new language.
Tests
These are practical tasks that we recommend completing after completing the course. The assignments will help you gain additional experience in programming and consolidate your acquired skills. Typically we recommend completing 3-5 tests. But if it doesn't work out, don't despair. Just come back to them later.
