How to rename a class in Eclipse?

In Eclipse, you can rename a class by following these steps:

1. Locate the package containing the class to be renamed in the Package Explorer view of Eclipse.
2. Right-click on the class you want to rename, then choose “Refactor” -> “Rename” (or simply use the shortcut Alt + Shift + R).
3. Please enter a new class name and press the “Enter” key.
4. Eclipse will scan all files in the project and update the class name wherever it is referenced.

Please note that if a renamed class is inherited or implemented by other classes, Eclipse may prompt you to also rename these subclasses or implementing classes. You can choose to do so as needed.

Additionally, if any compilation errors or other issues are encountered after renaming a class, it may be necessary to manually check and update the relevant code.
