### Question:
ColorRgba { @Override public String toString() { return new StringBuilder(MIN_LENGHT).append(getClass().getSimpleName()) .append(" [r=") .append(valueRed) .append(", g=") .append(valueGreen) .append(", b=") .append(valueBlue) .append(", a=") .append(valueAlpha) .append("]") .toString(); } ColorRgba(int r, int g, int b);  ColorRgba(int r, int g, int b, int a);  ColorRgba(int value); int getRgba(); int getRed(); int getGreen(); int getBlue(); int getAlpha(); @Override int hashCode(); @Override boolean equals(Object object); @Override String toString(); static final ColorRgba RED; static final ColorRgba GREEN; static final ColorRgba BLUE; static final ColorRgba CYAN; static final ColorRgba PURPLE; static final ColorRgba YELLOW; static final ColorRgba WHITE; static final ColorRgba GRAY_LIGHT; static final ColorRgba GRAY; static final ColorRgba GRAY_DARK; static final ColorRgba BLACK; static final ColorRgba TRANSPARENT; static final ColorRgba OPAQUE; }### Answer:
@Test void testToString() { assertEquals("ColorRgba [r=100, g=150, b=200, a=255]", new ColorRgba(100, 150, 200, 255).toString()); }
