Since its inception, Java has been among the most popular programming languages. Java is still relevant and quickly catching up with the trends in the current era of rapid innovations, where several programming languages that once had a significant industrial presence are long dead. Java learning is frequently more appealing to new developers. The greatest option to start with appears to be this timeless programming language. Your work must adhere to a set of standards to stand out from the hundreds of Java developers around you due to intense competition. It may seem that an executable, error-free code would be sufficient, but this is incorrect. A code must be written per a set of rules and coding standards. Java coding best practices may greatly enhance the quality of your code, making it far more flexible, reusable, and maintainable for both you and other people. Some Java best practices can speed up the execution of code, increasing its efficiency.

Java Coding Standards
Consider coding standards as a set of guidelines, methods, and best practices for writing cleaner, easier-to-read, more effective code with few mistakes. They provide a standard structure that software engineers can utilize to create complex, highly functioning code. Java coding standards are also a set of guidelines for its developers. Let us look at the details of java coding standards for different cases.
- Component coding standards
It is advised to write a component’s name followed by its purpose. The readability and maintainability of code are enhanced by this method.
- Coding Standards for Classes
The name of the class should typically begin with an uppercase term. If there are many words, each one should begin in capital letters.
- Coding Standards for Interface
The name of the interface should typically begin with an adjective in uppercase. If there are many words, each one should begin in capital letters.
- Coding Standards for methods
It states that the method name should typically begin with a lowercase verb or verb-noun combination. If there are many words, each one should begin in capital letters.
- Coding Standards for Variables
Typically, a variable name should begin with a lowercase noun. If there are many words, each one should begin in capital letters.
- Coding Standards for Constants
Constant names should often be nouns. It should only contain capital letters. If there are numerous words, the underscore symbol (_) is used to divide them. Constants are typically declared using the modifiers public, static, and final.
- Java Bean Coding Standards
A Java Bean is a straightforward Java class containing public getter and setter methods and private properties.

Google Java Coding Standards
The Google Java Coding Standards Guide standardizes the best practices for application coding. The manual is broken up into six sections, each of which covers a separate Java coding topic. The Google Java Style Guide is divided into the following sections:
- Source File Basics
- Source Files Structures
- Formatting
- Naming
- Programming Practices
- JavaDoc
The fundamentals of a source file include naming conventions, basic file encoding, Ascii character rules, and whitespace regulations. Each source file may contain license or copyright information, a package statement, import statements, and then exactly one top-level class, in that order, according to the Google coding standards. According to the Google Java code guidelines, brackets must be added where they are not required. Therefore, even when these structures only include one statement, braces must be used with all if, else, for, while, and do statements.
Conclusion
Good practices are guidelines. They can occasionally be disregarded. But consistency makes it easier to blend in with the group. Please feel free to add a few more while keeping the same general perspective. If you want to run your programs through Google in any way, you must adhere to the Google Java requirements. Learning these standards will help you become a better programmer because they are not only required for projects that run on Google but also constitute best practices for Java programming in general.
