**Java Naming Convention Rule:-** \

- It is a rule that is used to identify our identifiers in a code such as class, package, variable, constant, method, etc.
- If we don’t follow naming convention rules, it may generate confusion in the code.

## Advantages of naming convention rules:-

- The code can be read easily.
- The name should not start with a special character such as $, %, @.
- Easy to understand the code.
- If we know about the naming convention rule, we can easily write or implement the things in code.

## Types:-

**CamelCase** (camelCase): If the name contains multiple words, the first letter of the word always in small letter and after that each word with a capital letter.

Example: lastName, mostTalented, etc.

**PascalCase**: If the name contains multiple words, the first letter of every word is in capital letter.

Example: ActionListner, AudioWriter, etc.

## Method:-

- Always use camelcase for the method name.
- Such as println(), main(), etc.

## Syntax:-

```
Class Student
{
Void M1()
{
Code
}
}
```

## Class:-

- Always use PascalCase.
- Such as Employee, Student, etc.

## Syntax:-

```
class Student
{
code
}
```

## Variable:-

- Always use camelcase.
- Such as id, temp, etc.

## Syntax:-

```
class Student
{
int id;
code
}
```

## Package:-

- Always use camelcase.
- Such as java, lang, etc.
- If the name contains multiple words, they are separated by dots (.) like java.lang.package.

## Syntax:-

```
package java.lang.package;
class Student
{
code
}
```
