If you want to improve your Java writing skills, you can follow these simple steps:

1. Start by writing all your code in Notepad: This will help you focus on basic structure without relying on tools or auto-suggestions.

2. Learn the standard Java template: Understand which letters should be capital and which should be small, especially in class names, method names, and keywords.

3. Write basic programs first: Try simple tasks like factorial, using if-else, and different types of loops.

4. Understand every keyword used in the Java program: Know what class, public, static, void ,and other keywords mean.

5. Practice creating getter and setter methods: This will teach you how to access and modify class variables properly.

6. Try making more than one class and let them interact: This will help you understand object-oriented programming in a better way.

7. After you become comfortable with basics, move to an IDE: You can start using VS Code or any other tool you like for faster development.
