What Your Team Will Be Able to Do

After completing this training, your developers will:

• Set up and configure a Kotlin development environment with IntelliJ IDEA and Gradle — ready to start building immediately.
• Write clean, type-safe Kotlin code using variables, functions, and Kotlin’s expressive type system.
• Eliminate null pointer exceptions by applying Kotlin’s null safety mechanisms to write robust, error-free code.
• Handle complex logic confidently using control flow statements such as if, when, loops, and structured exception handling.
• Apply best practices for working with basic Kotlin types and writing maintainable code your team can build on.
• Build and run a Kotlin program from scratch — taking concepts from the classroom straight into your codebase.
