Best Practices and Coding Standards

Overview

Following best practices and coding standards ensures maintainable, efficient, and error-free Java code.

Topics

• Naming Conventions
• Code Formatting
• Avoiding Common Pitfalls
• Writing Readable and Maintainable Code
• Using Comments and Documentation

Examples

Naming Conventions

• Classes: PascalCase (e.g., MyClass)
• Methods and Variables: camelCase (e.g., myMethod, myVariable)
• Constants: UPPER_SNAKE_CASE (e.g., MAX_VALUE)

Code Formatting

• Use consistent indentation (e.g., 4 spaces).
• Place opening braces { on the same line as the declaration.

Avoiding Common Pitfalls

• Always close resources (e.g., streams, files) using try-with-resources.
• Avoid using null unnecessarily.

Writing Readable Code

// Bad
int x = 10; if(x>5){System.out.println("x is greater than 5");}

// Good
int x = 10;
if (x > 5) {
    System.out.println("x is greater than 5");
}
