The Query class is marked with the @Deprecated annotation, which is no longer recommended. However, for compatibility or other reasons, it needs to be retained for the time being.
When Eclipse detects @Deprecated, it will prompt with a strikethrough.
The strikethrough means that although it can still be used, it is not recommended. Future versions are likely to be incompatible. Often, other classes or functions with the same function in the current code base will replace it. Just look for it
