How to standardize Java code?

To standardize Java code, you can follow the following aspects of standards: 1. Naming conventions:

Class names should be in CamelCase, with the first letter capitalized, for example: MyClass.

– Camel case is used for naming methods, with the first letter in lowercase, for example: getAge().

– Variable names should be in camel case, starting with a lowercase letter, for example: myVariable.

Constant names should be in all capital letters, with words separated by underscores, for example: MAX_NUM.Indentation and spacing:

Use four spaces for indentation, do not use tab characters.

– Make sure to add spaces before and after operators, for example: int a = 1 + 2;

The left and right parentheses in the method should be surrounded by spaces. 3. Commenting guidelines:

Use JavaDoc comments above classes, methods, and fields for explanation.

4. Utilize single-line comments within the key steps of the method to provide explanations.

Every class should have a public constructor.

Try to avoid using deeply nested if-else statements by splitting them into multiple methods. 5. Proper exception handling:

Handle exceptions at places where they might occur to avoid throwing uncaught exceptions.

Do not use empty catch blocks, at least add a log message inside the catch block.6. Class design standards:

Single Responsibility Principle: Each class is only responsible for one functionality.

Open-Closed Principle: Open for extension, closed for modification.

Interface segregation principle: use multiple small, specialized interfaces instead of one large, general interface. 7. Utilize tools for code inspection:

Utilize static code analysis tools such as Checkstyle, FindBugs, etc.

– Use the built-in code formatting tool in your IDE to standardize the code. These are some common Java coding conventions that can be adjusted and supplemented according to the specific requirements of the project. Standardized code can improve code readability, maintainability, and facilitate team collaboration.
