### Question:
ColorUtilities { public static Color convertFromColorString(String color) { Color aColor = null; if (color != null) { try { Field colorField = Color.class.getField(color.toUpperCase()); try { aColor = (Color)colorField.get(null); } catch (IllegalAccessException e) { LOGGER.error("Could not access field by reflection.", e); } } catch (NoSuchFieldException e) { String[] colors = color.split("-"); if (colors.length == 4) { try { aColor = new java.awt.Color(Integer.parseInt(colors[0]), Integer.parseInt(colors[1]), Integer.parseInt(colors[2]), Integer.parseInt(colors[3])); } catch (NumberFormatException nfe) { LOGGER.warn("Failed to parse color [" + color + "]: " + nfe, nfe); } catch (IllegalArgumentException iae) { LOGGER.warn("Failed to parse color [" + color + "]: " + iae, iae); } } } } return aColor; } private  ColorUtilities(); static Color blendColors(Color color1, Color color2); static Color brighten(Color input, double factor); static Color convertFromColorString(String color); static Color convertFromHexString(String color, int redIndex, int greenIndex, int blueIndex); static Color convertFromHexString(String color, int redIndex, int greenIndex, int blueIndex, int alphaIndex); static String convertToHexString(Color color, int redIndex, int greenIndex, int blueIndex); static String convertToHexString(Color color, int redIndex, int greenIndex, int blueIndex, int alphaIndex); static String convertToRGBAColorString(Color aColor); static Color darken(Color input, double factor); static Color lighten(Color color); static int getBrightness(Color color); static Color getContrastingColor(Color color); static Color getAlternateColor(Color color, int shift); static boolean isEqual(Color c1, Color c2); static boolean isEqualIgnoreAlpha(Color c1, Color c2); static Color opacitizeColor(Color startingColor, float alpha); static Color opacitizeColor(Color startingColor, int alpha); static final int COLOR_COMPONENT_MAX_VALUE; }### Answer:
@Test public void testConvertFromColorString() { Assert.assertEquals(Color.RED, ColorUtilities.convertFromColorString("red")); Assert.assertEquals(Color.RED, ColorUtilities.convertFromColorString("RED")); Assert.assertEquals(new Color(250, 0, 0, 255), ColorUtilities.convertFromColorString("250-0-0-255")); Assert.assertEquals(new Color(250, 0, 0, 254), ColorUtilities.convertFromColorString("250-0-0-254")); Assert.assertEquals(new Color(0, 250, 0, 255), ColorUtilities.convertFromColorString("0-250-0-255")); Assert.assertEquals(new Color(0, 250, 0, 254), ColorUtilities.convertFromColorString("0-250-0-254")); Assert.assertEquals(new Color(0, 0, 250, 255), ColorUtilities.convertFromColorString("0-0-250-255")); Assert.assertEquals(new Color(0, 0, 250, 254), ColorUtilities.convertFromColorString("0-0-250-254")); Assert.assertNull(ColorUtilities.convertFromColorString("")); Assert.assertNull(ColorUtilities.convertFromColorString("255")); }
