### Question:
Conus3d extends Applet { public void create () { final SimpleUniverse simpleUniverse = new SimpleUniverse(); final BranchGroup branchGroup = new BranchGroup(); final Cone cone = new Cone(mRadius, mConusHeight); branchGroup.addChild(cone); final DirectionalLight lightDirection = J3DUtils.createDefaultLight(); branchGroup.addChild(lightDirection); simpleUniverse.getViewingPlatform().setNominalViewingTransform(); simpleUniverse.addBranchGraph(branchGroup); } Conus3d(final float radius, final float conusHeight); void create(); float getRadius(); void setRadius(final float radius); float getConusHeight(); void setConusHeight(final float conusHeight);  }### Answer:
@Test public void test () { final Conus3d conus3d = new Conus3d(0.5f, 1.0f); conus3d.create(); }
