Why we should follow the naming conventions in Java?

Java Object Oriented Programming Programming

Naming conventions in Java make programs more understandable by making them easier to read.

In Java, class names generally should be nouns, in title case with the first letter of each separate word capitalized. and interface names generally should be adjectives, in title case with the first letter of each separate word capitalized.

Why should follow the Java naming standards

To reduce the effort needed to read and understand source code.
To enable code reviews to focus on more important issues than arguing over syntax and naming standards.
To enable code quality review tools to focus their reporting mainly on significant issues other than syntax and style preferences.

Naming Conventions for a different type of Identifiers

Package

The Package name should be in all lower case.

Example

package com.tutorialspoint;

Interface

The Interface name should start with an upper case character.

Example

interface TutorialsPointInterface {
  // some statements
}

Class

All the words of a class name should start with an upper case character.

Example

class TutorialsPointClass {
  // some statements
}

Method

Methods should be verbs with the first letter lowercase and the first letter of each internal word capitalized.

Example

class TutorialsPointClass {
   void printMessage() {
   }
}

Variable

The first word should be in lower case and the internal words start with capital letters.
Variable names should not start with underscore _ or dollar sign $ characters.

Example

class TutorialsPointClass {
   int rollNum;
   String firstName;
   String lastName;
}

Constant

All the characters should be in upper case.

Example
