BasicCource

An educational Java SE project with simple examples of core language topics.

The project is split into packages: each package demonstrates one topic using small, easy-to-read examples. This makes it convenient for reviewing syntax and practicing how to run individual classes with main.

What's in the project

• src/variables - variables and operators.
• src/conditionals - branching (if/else, switch, ternary operator).
• src/loops - loops (for, foreach, while).
• src/arrays - one-dimensional and two-dimensional arrays.
• src/inputs - input handling.
• src/objects - OOP basics using the Person class.
• src/packet1 and src/packet2 - access modifiers and cross-package access.
• src/Main.java, src/App.java - entry points for running examples.

Folder structure

• src - source code.
• bin - compiled .class files.
• lib - external libraries (if needed).

How to run

Option 1: via VS Code

1. Open the project in VS Code.
2. Choose a class that contains main (for example, src/loops/Loop_For.java).
3. Click Run above the main method, or run it from Run and Debug.

Option 2: via terminal

From the project root:

javac -d bin src/Main.java
java -cp bin Main

To run a class inside a package, use its fully qualified name, for example:

javac -d bin src/loops/Loop_For.java
java -cp bin loops.Loop_For

Project goal

Practice and reinforce core Java topics through short, self-contained examples:

• language syntax;
• conditions and loops;
• arrays and input;
• basics of classes, objects, and access modifiers.
