### Question:
LineShape extends Shape3D { public void create () { final LineArray lineArray = createLineArray(); final LineAttributes lineAttributes = createLineAttributes(); final Appearance appearance = new Appearance(); appearance.setLineAttributes(lineAttributes); this.setGeometry(lineArray); this.setAppearance(appearance); } LineShape(final float lineWidth, final float[] verts, final float[] colors); void create(); float getLineWidth(); void setLineWidth(final float lineWidth); float[] getVerts(); void setVerts(final float[] verts); float[] getColors(); void setColors(final float[] colors);  }### Answer:
@Test public void testLine3dShape () { final Line3dShape line3dShape = new Line3dShape(10.0f, verts, colors); line3dShape.create(); }
