- Write a main method
- Use proper Java syntax
- **Outcome**: Create a working "Hello, World!" program

2. **IntelliJ Basics**
- Navigate the IDE interface
- Use code completion
- Run Java programs
- **Outcome**: Demonstrate IDE proficiency through program creation and execution

3. **Variables and Operations**
- Declare and initialize variables
- Perform basic arithmetic
- Use proper data types
- **Outcome**: Create a program that performs calculations and displays results

4. **User Interaction**
- Get input from users
- Validate input properly
- Format output clearly
- **Outcome**: Build an interactive program that responds to user input

5. **Code Organization**
- Structure code into methods
- Use constants appropriately
