What are the best practices for using variables in Java?

Some best practices include using meaningful variable names, following naming conventions, and initializing variables.

Can you explain why meaningful names are important?

Meaningful names improve code readability and maintainability, making it easier for others to understand your code.

What naming conventions should I follow?

Use camelCase for variable names, start with a lowercase letter, and avoid using single-letter names except for loop counters.

Should I declare variables at the top of the method?

It's generally a good practice to declare variables close to where they are used to improve code clarity.
