In java public classes must be in files with corresponding name. So class Dogmust be in file Dog.java. Deprecation is not a compiler error, but classname-filename is.
在 java 中，公共类必须在具有相应名称的文件中。所以 classDog必须在 file 中Dog.java。弃用不是编译器错误，但类名文件名是。

From error I can guess, you have saved file with another name other than class name Holeintext
从错误我可以猜到，您保存的文件使用了类名以外的其他名称 Holeintext
public class Holeintext {
...
....
}
Solution:
解决方案：
1.Remove public access- specifier from class
1.从类中删除公共访问说明符
class Holeintext{
....
...
}
2.or save file with Holeintext.java
2.或保存文件 Holeintext.java
