Yesterday i was studying the Java 1.5 language specification, and i came upon this cool syntactic feature. Its the java static import. With it you can introduce to your class the static members of another class or interface. As an example:
public interface Test {
	public static final int NUMBER_ONE = 1;
	public static final int NUMBER_TWO = 2;
and the class:
import static Test.*;

public class TestClass {
	public static void main(String[] args) {
		System.out.println(NUMBER_ONE + NUMBER_TWO);
