### Question:
ColorUtil { static boolean isNotFullyTransparent(final Color color) { return !isFullyTransparent(color); }  static String colorTag(Color color); static String prependColorTag(final String str, final Color color); static String wrapWithColorTag(final String str, final Color color); static String toHexColor(final Color color); static Color colorLerp(final Color a, final Color b, final double t); static String colorToHexCode(final Color color); static String colorToAlphaHexCode(final Color color); static boolean isAlphaHex(String hex); static boolean isHex(String hex); static int constrainValue(int value); static Color fromString(String string); static Color fromHex(String hex); static final int MAX_RGB_VALUE; static final int MIN_RGB_VALUE; }### Answer:
@Test public void isNotFullyTransparent() { for (Color color : COLOR_HEXSTRING_MAP.keySet()) { assert(ColorUtil.isNotFullyTransparent(color)); } assert(!ColorUtil.isNotFullyTransparent(new Color(0, 0, 0, 0))); assert(ColorUtil.isNotFullyTransparent(new Color(0, 0, 0, 1))); }
