How use Spaces instead of Tabs in Eclipse Java editor? Example

 To configure Eclipse to use spaces instead of tabs in the Java editor, you can follow these steps:

• Open Eclipse preferences: Launch Eclipse and go to "Window" -> "Preferences" (on Windows) or "Eclipse" -> "Preferences" (on macOS).

• Navigate to the Java editor settings: In the Preferences window, expand the "Java" category and select "Code Style" -> "Formatter".

• Create or edit the formatter profile: In the Formatter tab, you can either create a new formatter profile or modify an existing one. If you want to create a new profile, click on the "New" button and give it a name. Otherwise, select the existing profile you want to modify.

• Configure the indentation settings: In the "Indentation" tab, you'll find options to customize the indentation settings. To use spaces instead of tabs, follow these steps:

• Select the "Spaces only" option for "Tab policy".

• Set the "Indentation size" to the number of spaces you want to use for each level of indentation. For example, if you want to use 4 spaces for indentation, enter "4" in the "Indentation size" field.

• Optionally, you can also set the "Tab size" to the same value as the "Indentation size" to ensure consistent spacing when mixing tabs and spaces (though it's recommended to use spaces consistently).

• Apply and save the formatter settings: Click "Apply" to see a preview of the changes in the "Preview" section. If you're satisfied with the preview, click "OK" to save the formatter settings.

• Set the formatter profile as the default: In the Preferences window, go to "Java" -> "Code Style" -> "Formatter". Select the formatter profile you created or modified in the "Active profile" dropdown list. Click "OK" to apply the changes.

By following these steps, you have configured Eclipse to use spaces instead of tabs for indentation in the Java editor. Any new code you write or format using Eclipse's auto-formatting feature will adhere to these indentation settings.
