static import

In order to access static members, it is necessary to qualify references. For example, one must say:

double r = Math.cos(Math.PI * theta);

The static import construct allows unqualified access to static members.

import static java.lang.Math.PI;

or:

import static java.lang.Math.*;

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

double r = cos(PI * theta);

The static import declaration imports static members from classes, allowing them to be used without class qualification.
