The Complete Kotlin & Android Developer Course: Build Apps

Install and configure the Java JDK on a Windows PC, including downloading the Oracle JDK, running the installer, setting the system PATH, and verifying installation with java and javac.

Install the IntelliJ IDEA community edition on Windows, configure the JDK, and create a Hello world Java project to run and see output.

Install Android Studio on Windows, download it from the official site, install the required SDK tools, create a new Hello Android project, and configure an emulator to run the app.

Install IntelliJ IDEA on Mac by downloading the community edition, then create a simple Java project to run hello world and verify the setup.

Install and verify Java on Linux Ubuntu using terminal commands, including adding the Oracle Java repository, updating packages, installing Java, setting environment variables, and running a hello world program.

Learn to check for updates, update and restart IntelliJ, and install the material theme plugin to customize your IDE in the Kotlin Android development masterclass.

Update the Kotlin plugin to the latest stable version via the stable update channel. Create a new Kotlin project, print hello there, and run it on JDK 9 to verify.

Create a new Kotlin project on the JVM, configure the Java SDK, and write a main function that prints hello world, then run to see the output.

Learn how to create and use variables in Kotlin by declaring var named values, assigning strings, and printing values with print line, including string concatenation and adding spaces.

Learn how string variables work in Kotlin, using explicit and implicit typing to assign and update a country bucket from Spain to Mozambique, with string type enforced.

Learn Kotlin variable types by working with integers and strings, practice type safety with explicit integer declarations, concatenate strings with variables and use $variable syntax, and basic null handling.

Explore booleans in Kotlin Android development, using true or false to control program flow with conditions, declare boolean types, and handle nullability and optional semicolons.

Learn how to define and use floats in Kotlin, distinguish floats from doubles, and apply the f suffix to enforce a float type with examples like 0.5 and 23.4.

Master Kotlin char variable types by distinguishing characters from strings using single quotes versus double quotes, and practice concatenation and basic types like int, double, float, and boolean.

Learn how to declare mutable and immutable variables in Kotlin using var and val. Use var for reassignable values and val for constants like pi.

Learn to add two numbers in Kotlin by declaring var with int type, computing the sum, and displaying it using string interpolation with ${}.

Learn to multiply two numbers in code using the asterisk operator, set up operands as variables, and display the result.

Learn how to convert between data types in Kotlin, such as int to string and double to int, with practical type casting and boundary cases.

Explore conditional operators and if statements in Kotlin, define conditions such as greater than or less than, execute code when true, and use else for alternatives.

Explore logical operators in Kotlin, learning how and, or, and not form boolean expressions, drive if statements, and control flow through true and false scenarios.

Explore the do while loop, which runs the body first and then checks the condition, guaranteeing at least one execution; use a counter and inline checks like multiples of three.

Create a Kotlin console app that prompts for number of siblings, uses a do-while loop and a when expression to validate input, and exits when the answer, 12, is entered.

Understand function return types in Kotlin, from void to integers and strings, using return and explicit types to compose operations like multiply and divide.

Explore variable scope in Kotlin, distinguishing local function variables from global ones and illustrating how parameters and access change with scope.

Explore the foundations of object oriented programming by defining classes as blueprints for objects, with properties and methods, and use a constructor to create multiple instances like houses.

Learn how getters and setters enforce encapsulation by keeping the class's internal state as a black box, while Kotlin allows property access or explicit get/set methods for a house object.

Explore how inheritance uses a parent animal class to supply properties and methods to child classes like cat, lion, and dog, reducing redundancy and increasing code flexibility.

Explore how to extend existing Kotlin classes with extension functions, using a receiver type to add behavior to strings and numbers, including removing first and last characters and doubling numbers.

Learn how to define a nested (inner) class inside an outer class, access its members from the outer scope, and instantiate the nested class to call its functions.

Learn how inner classes in Kotlin access outer class members, distinguish nested from inner classes, and instantiate and call outer methods and member variables from within the inner class.

Explore operator overloading in Kotlin by overloading the plus operator for primitive types and a point class, yielding a new point with summed coordinates, then tackle minus overloading.

Learn how abstract classes work in Kotlin Android development by building a graphic object hierarchy. Implement abstract methods and concrete logic, and instantiate concrete shapes like circle and triangle.

Explore generics and generic classes, using a type parameter T to build flexible, type-safe structures like login and person, with concrete examples of string and boolean types.

Understand how an array acts as a memory rectangle of indexed elements, with integers as examples, and learn to access values by index and create arrays in Kotlin.

Learn to create generic arrays in Kotlin, initialize a five-slot array, access elements by index, and iterate with a for loop to print or update items.

Explore safe array iteration in Kotlin by using the array size to bound the index, avoiding out-of-bounds errors with zero-based indexing and size minus one.

Explore array lists in Kotlin and learn how they extend plain arrays with generics, flexible sizing, and practical methods like add, get, set, remove, contains, and iteration.

Create and use a hash map to store key value pairs, specify key and value types, and iterate keys to retrieve values such as Mary and John.

Learn to write to a text file in Kotlin with a file writer, including writing hello world messages, closing the writer, and handling exceptions with try and catch.

Develop a kotlin reader-write app with a menu to write messages to a file and read them back, illustrating modular functions and simple file operations.
