import is a Java keyword.

It declares a Java class to use in the code below the import statement. Once a Java class is declared, then the class name can be used in the code without specifying the package the class belongs to.

Use the '*' character to declare all the classes belonging to the package.


Computer code
import package.JavaClass;
import package.*;

The static import construct allows unqualified access to static members without inheriting from the type containing the static members:

   import static java.lang.Math.PI;

Once the static members have been imported, they may be used without qualification:

   double r = cos(PI * theta);

Caveat: use static import very sparingly to avoid polluting the program's namespace!
