It is possible to import just one static method, or member in extend? I know that it is possible to import all static methods by *, like in this example ...
import static example.Types.*
But I need only one.

If what you're looking for is something like the using
keyword from C# or C++ java doesn't have that feature.
Java 5 added an import static option that allows static variables (typically constants) to be referenced without qualifying them with a class name.
For example, after
import static java.awt.Color;
It would then be possible to write
Color background = RED;
instead of
Color background = Color.RED;
Example above have been taken from: Java: packages and Import. The site used for the example seems to be out of date, sorry any trouble this can cause
See How java import works for more detail.
Yes it is possible.
import static System.out;
You can then merely write
out.println("Doobedoo");
Which will save you from typing the System.out
part several times over but is potntially confusing for anyone trying to follow you code.
Use it sparingly and generally only for constants ( static final ).
