Java Coding Standards

When reviewing or generating Java code, follow these rules:

File Naming

Source files: PascalCase matching the public class name (e.g.,
```
UserService.java
```
)
One public class per file: File name must match the public class name exactly
Test files: Class name with
```
Test
```
suffix (e.g.,
```
UserServiceTest.java
```
)
Interface files: PascalCase (e.g.,
```
Comparable.java
```
,
```
UserRepository.java
```
)

Package Naming

Packages: All lowercase, dot-separated (e.g.,
```
com.example.service
```
,
```
org.project.utils
```
)
No underscores or hyphens in package names
Follow reverse domain name convention

Variable Naming

Local variables: camelCase (e.g.,
```
userName
```
,
```
isActive
```
,
```
totalCount
```
)
Instance variables: camelCase (e.g.,
```
userId
```
,
```
createdAt
```
)
Constants: UPPER_SNAKE_CASE with
```
static final
```
(e.g.,
```
MAX_RETRIES
```
,
```
DEFAULT_TIMEOUT
```
)
Boolean variables: Prefix with
```
is
```
,
```
has
```
,
```
can
```
,
```
should
```
(e.g.,
```
isEnabled
```
,
```
hasPermission
```
)

Method Naming

Methods: camelCase, verb or verb phrase (e.g.,
```
calculateTotal()
```
,
```
getUserById()
```
)
Getters:
```
get
```
prefix (e.g.,
```
getName()
```
,
```
getId()
```
)
Setters:
```
set
```
prefix (e.g.,
```
setName()
```
,
```
setId()
```
)
Boolean getters:
```
is
```
or
```
has
```
prefix (e.g.,
```
isActive()
```
,
```
hasChildren()
```
)
Factory methods:
```
create
```
,
```
of
```
,
```
from
```
,
```
valueOf
```
(e.g.,
```
createInstance()
```
,
```
of()
```
)

Class/Interface Naming

Classes: PascalCase, noun or noun phrase (e.g.,
```
UserService
```
,
```
OrderProcessor
```
)
Interfaces: PascalCase, adjective or noun (e.g.,
```
Comparable
```
,
```
UserRepository
```
)
Abstract classes: PascalCase, optionally prefix with
```
Abstract
```
(e.g.,
```
AbstractHandler
```
)
Exception classes: PascalCase with
```
Exception
```
suffix (e.g.,
```
InvalidInputException
```
)
Enums: PascalCase for type, UPPER_SNAKE_CASE for values

Generics

Type parameters: Single uppercase letter (e.g.,
```
T
```
,
```
E
```
,
```
K
```
,
```
V
```
)
Meaningful names: When clarity needed (e.g.,
```
<Key, Value>
```
)

Organization

Package statement first
Import statements (java., javax., third-party, project imports)
Class declaration with fields, constructors, methods
Public methods before private methods
