Java Packages and GitHub Classroom

Study Notes

Accept invitation for GitHub classroom provided by your instructor, found under “Homework” on MyCourses.
Link your GitHub account to your name in the class roster before accepting the assignment.
After accepting, copy the URL of the created repository for future reference.
Clone the empty repository to your local file system to start working on your project.
Create a new IntelliJ project within the cloned repository and push it to GitHub to initiate activities.

Java allows for the organization of multiple classes through the use of packages, which create a namespace.
Package names consist of words separated by dots, such as my.example.pkg.
While packages may appear hierarchical in naming, they function as flat namespaces without special relationships.
In the file system, packages are represented as folders, which can be hierarchical but do not imply relationships between them.

To create a package in IntelliJ, right-click on the src folder and select New → Package.
Name the new package (e.g., activities) and click OK to create a new folder in your src directory.
Implement project solutions within the newly created package folder.

Programs consist of statements, often referred to as lines of code, containing instructions for execution.
Statements in Java begin at the start of a line and conclude with a semicolon.
Statements are executed sequentially from top to bottom, and the program exits after the final statement has been executed.
Sequential execution is known as sequential flow of control.

Java uses the Head { Body } Pattern to structure programs, including class or main method declarations in the Head.
The Body follows the Head and consists of one or more related statements.
The Body is typically enclosed in curly braces ({ }) to denote the start and end of statement blocks, which organize code effectively.
