How to resolve the issue of failed code formatting in IDEA.

When the code formatting feature in the integrated development environment (IDE) doesn’t work, you can try the following troubleshooting methods:

1. Check IDE settings: First, make sure that the code formatting option in the IDE is enabled and configured correctly. Some IDEs may require manual enabling of this function. Look for the settings options in the IDE, check for any options related to code formatting, and ensure that it is enabled.
2. Check code standards: If code formatting fails, it may be because the code does not adhere to the IDE’s coding standards. Look for the IDE’s coding standards documentation and ensure that the code meets the requirements. If necessary, make necessary adjustments to the code to comply with the coding standards.
3. Utilize plugins or extensions: Some IDEs may not have built-in code formatting features, but you can add this functionality by installing plugins or extensions. Check the IDE’s plugin marketplace or official website, search for a code formatting plugin suitable for your IDE, and follow the instructions provided to install and configure it.
4. Try using other tools: If the IDE’s code formatting feature continues to fail, you can try using other independent code formatting tools. For example, tools like Prettier and Eslint can run independently from the IDE and have powerful code formatting capabilities. Copy the code into these tools, format it, and then copy the formatted code back into the IDE.
5. Restart IDE: Sometimes, IDE may encounter issues for certain reasons, resulting in failed code formatting. Try restarting the IDE to see if it can resolve the issue.

If the above methods do not work, you can try asking on relevant technical forums or communities to receive more detailed help and solutions.
