Where must a package statement be located in a Java source code file?

• A. Anywhere in the file
• B. Before any import statements
• C. At the beginning of the file
• D. After the class declaration

Answer: (C)

A package statement must be located at the beginning of a Java source code file, specifically before any other declarations except for comments or documentation. This is a requirement outlined in the Java Language Specification, which states that the package declaration must be the first line in the source file in order to properly define the namespace for the classes contained within that file.

Positioning the package statement at the top ensures that any classes defined in the file are associated with the appropriate package and helps maintain a structured organization of classes and interfaces in larger applications.

Other declarations, such as import statements, need to follow the package statement, as they rely on the proper context established by the package declaration.
