Java naming conventions are essential for writing clean, readable, and standardized code in Java applications.Classes and interfaces should follow PascalCase for names, ensuring clarity and adherence to industry standards.Class names should represent entities and avoid abbreviations, while interface names can be adjective-like or noun-based.Method names should use camelCase and describe actions performed, enhancing clarity and purpose.Variables should be named descriptively in camelCase to reflect their data, improving readability and maintainability.Constants should be written in UPPER_CASE with descriptive names, providing clarity on their purpose.Package names should be lowercase with a reversed domain name structure to ensure uniqueness and readability.Enum names should follow PascalCase, with constants in UPPER_CASE for clear distinction as fixed values.Getter and setter methods should adhere to getVariableName() and setVariableName(value) formats for consistency.Exception classes should end with 'Exception' in PascalCase, and Java files should match class names exactly.
