Mastering Java Development with IntelliJ IDEA and JavaFX

Master Java basics by creating a new IntelliJ project, writing a main method, and printing with System.out.print and println. Understand single-line and multi-line comments in Java.

Explore Java variables and data types, including strings, integers, floats, characters, booleans, and types like byte, short, int, long, float, double. Learn declaration, initialization, printing, final constants, and string concatenation.

Explore string operations in Java, including length, casing, concatenation, indexing, and numeric-string interactions, alongside boolean logic and basic math functions like max, min, sqrt, abs, and random.

Explore Java control flow by building conditions with if, else if, and switch statements, compare variables, demonstrate single-line and multi-line forms, and manage cases with break and default.

Master the while and for loops in Java, exploring initialization, conditions, and increments, and learn how break, continue, and for-each loops control flow using practical examples with numbers and arrays.

explore Java arrays, including declaring and initializing string and integer arrays, accessing and updating elements, using length for iteration, and working with multi-dimensional arrays.

Explore how to define and call Java methods, including static void helpers, passing parameters, returning values, and overloading with different parameter types to reuse code across a class.

Create classes and objects in Java using the car blueprint as an example, and learn how attributes like gears and manual vs automatic, along with methods, support object-oriented programming.

Build and manage class methods and attributes in Java by turning a lamp on and off, and using constructors to initialize name and location with default or multiple constructors.

Explore Java inheritance by modeling an animal hierarchy—animal, dog, and cat—using extends to reuse eat and display methods and add unique behaviors like barking and pour.

Explore IntelliJ project files by examining the iml module file, understand module configuration, SDK settings, and how multiple modules enable separate frameworks and build scripts within a single project.

Explore the .idea folder at the project root, which stores configuration files for the entire project, and learn how changes reflect when editing via the graphical user interface.

Identify the src folder as the workspace for writing your source code, including the main class and Java packages.

Discover the out folder in IntelliJ, which appears after you run your Java project and holds the executable class files, with a decompiler option and notes on external libraries.

Explore the IntelliJ IDEA user interface, including the main menu bar, navigation bar, toolbars, project and editor windows, and key tool windows like terminal and version control.

Navigate and manage your Java project in IntelliJ IDEA using the project tool window. Resize, hide, or switch views (project, packages, libraries, production, tests) to focus on relevant files.

Explore how the structure tool window and navigation bar in IntelliJ reveal the current class structure, including fields, methods, lambdas, and inherited members, and streamline project navigation.

Master scratch files in IntelliJ to experiment with code before integrating it, and use to-do tasks with the Todo window to track future work.

Explore the problems tab to track warnings and jump to their exact locations. Use the built-in terminal for fast commands, version control, and Maven or Gradle work inside the IDE.

Master the main editor window, fold code with brackets, and run your Java programs. Explore problem views, dynamic code review, and efficient navigation for long files.

Master navigation in IntelliJ by using the search everywhere feature (double shift) to find files, actions, and settings, and learn keyboard shortcuts to speed up coding.

Master faster file and class access in IntelliJ IDEA using hover search, the project tool window, and quick actions; locate files, classes, and symbols with command O or double shift.

Discover how to check recent file changes in IntelliJ with shortcuts like E (Mac) or Ctrl E (Windows). View recent edits, actions, and class definitions for project and external libraries.

Show a Java class’s member variables using IntelliJ’s structure window and command seven, then explore class hierarchy with control H to understand project structure.

Learn to generate boilerplate code in IntelliJ for a Java class, including constructors, getters, and setters, and test them by creating a worker with salary and name.

Learn how IntelliJ inspects your code to detect warnings and errors before compiling. See how to fix issues with quick actions, remove unreachable statements, and import classes.

Inspect your code with IntelliJ by creating a dedicated project, moving the main class, and using the problems window to spot errors, warnings, and typos.

Explore how to inspect an entire IntelliJ project for code style, data-flow, and maintainability issues, uncovering warnings across client-server and socket projects and guiding fixes.

Learn to remove redundant warnings in Java code via IntelliJ inspection profiles. Adjust variable declaration warnings in constructors and manage inspections across Java versions.

Master code refactoring in IntelliJ by extracting methods, renaming variables and methods, and moving classes, and learn when to refactor for cleaner, maintainable Java code.

Use IntelliJ to automate refactoring by extracting complex expressions into a method. Learn to extract methods with right-click refactor or option-command-M, and apply this to a withdraw example.

Move static members between classes with IntelliJ's refactoring. Use Move Member (F6) to transfer a member, update references, and align methods and variables across classes.

Master change signature refactoring in IntelliJ to modify method and class signatures, turn classes into generics, automatically update calls and overrides, and add or remove parameters.

Master real time live templates in IntelliJ to speed up Java coding, such as creating a main method with a template, printing with templates, and generating loops for faster productivity.

Learn to parameterize templates in IntelliJ by using the for and for each live templates to generate a complete for loop, set its iteration limit, and print results efficiently.

Explore how to use surround live templates in IntelliJ to wrap selected code with blocks like try-catch and if statements, and leverage live templates to speed Java development.

Learn how to create, customize, and share IntelliJ live templates in Java projects, export and import settings, and reuse templates across machines.

Identify syntax, runtime, and logic errors in Java with IntelliJ IDEA, and learn to diagnose syntax mistakes, runtime issues like division by zero, and use the java.util logger for debugging.

Explore the IntelliJ debugger by creating a Java project, building a name list, and using methods to print, add, and remove names while stepping through code and setting breakpoints.

Master how to use the IntelliJ debugger to step into, over, and out with custom breakpoints, while inspecting live variables.

Master the essentials of integrating git with IntelliJ, create and manage a local git repository, install git, use clone, init, push and pull, and connect to GitHub for version control.

Learn how to add and commit changes to a git repository using IntelliJ, manage commits with the commit window, handle git ignore, and work with master, develop, and feature branches.

Learn to ignore files in a git project by creating a .gitignore with patterns, add it to version control, and optionally generate java-specific ignores with an IDE plugin.

Learn to integrate Java code with a remote GitHub repository using IntelliJ, including signing in, sharing projects, and committing and pushing changes with gitignore and gists.
