How are Java source code files named?

  • A Java source code file takes the name of a public class or interface that is defined within the file.
  • A source code file may contain at most one public class or interface.
  • If a public class or interface is defined within a source code file, then the source code file must take the name of the public class or interface.
  • If no public class or interface is defined within a source code file, then the file must take on a name that is different than its classes and interfaces.
  • Source code files use the .java extension.
