Which two packages are automatically imported into the java source file by the java compiler?

A.
java.lang

B.
java.awt

C.
javax.net

D.
java.*

E.
The package with no name

For convenience, the Java compiler automatically imports three entire packages for each source file:
(1) the package with no name, (2) the java.lang package, and (3) the current package (the package for the current file).
Note: Packages in the Java language itself begin with java. or javax.
Incorrect answers:
java.awt: basic hierarchy of packages for native GUI components;
javax.net: networking operations, sockets, DNS lookups, etc.
