This type of declaration has been available since J2SE 5.0. Static import declarations allow access to static members defined in another class, interface, annotation, or enum; without specifying the class name:
import static java.lang.System.out; //'out' is a static field in java.lang.System
public class HelloWorld {
public static void main(String[] args) {
/* The following line is equivalent to
System.out.println("Hi World!");
and would have been incorrect without the import declaration. */
out.println("Hello World!");
}
}
Import-on-demand declarations allow to import all the fields of the type:
import static java.lang.System.*;
/* This form of declaration makes all
fields in the java.lang.System class available by name, and may be used instead
of the import declaration in the previous example. */
Enum constants may also be used with static import. For example, this enum is in the package called screen:
public enum ColorName {
RED, BLUE, GREEN
};
It is possible to use static import declarations in another class to retrieve the enum constants:
import screen.ColorName;
import static screen.ColorName.*;
public class Dots {
/* The following line is equivalent to 'ColorName foo = ColorName.RED',
and it would have been incorrect without the static import. */
ColorName foo = RED;
void shift() {
