### Question:
Cylinder3d extends Applet { public void create () { final SimpleUniverse universe = new SimpleUniverse(); final BranchGroup branchGroup = new BranchGroup(); final Cylinder cylinder = new Cylinder(mRadius, mCylinderHeight); branchGroup.addChild(cylinder); final DirectionalLight light = J3DUtils.createDefaultLight(); branchGroup.addChild(light); universe.getViewingPlatform().setNominalViewingTransform(); universe.addBranchGraph(branchGroup); } Cylinder3d(final float radius, final float cylinderHeight); void create(); float getRadius(); void setRadius(final float radius); float getCylinderHeight(); void setCylinderHeight(final float cylinderHeight);  }### Answer:
@Test public void test () { final Cylinder3d cylinder3d = new Cylinder3d(.5f, 1.0f); cylinder3d.create(); }
