Relationship between Java file names and content

Myclass. Java is a Java source file, which allows the class without myclass

At the beginning of this sentence, I was very confident that it was wrong.

Name the file and the corresponding class will appear in the content.

Otherwise, the meaning of the file cannot be found.

Right ··············

But this is the case with human intuition.

This class does not exist. For example, the content in myclass. Java is class myobject {}. Note that the object cannot be public. Otherwise, the object name must be the same as the object name.

The key reason is whether the public keyword exists ·········

I am wrong ···········
