Java中颜色的String和Color对象之间的互相转换

随机生成一种颜色
Color color = new Color(
				(new Double(Math.random() * 128)).intValue() + 128,
				(new Double(Math.random() * 128)).intValue() + 128,
				(new Double(Math.random() * 128)).intValue() + 128);

 

Color对象和十六进制颜色编码之间的转换

 

public static String Color2String(Color color) {
		String R = Integer.toHexString(color.getRed());
		R = R.length() < 2 ? ('0' + R) : R;
		String B = Integer.toHexString(color.getBlue());
		B = B.length() < 2 ? ('0' + B) : B;
		String G = Integer.toHexString(color.getGreen());
		G = G.length() < 2 ? ('0' + G) : G;
		return '#' + R + B + G;
	}

public static Color String2Color(String str) {
		int i = Integer.parseInt(str.substring(1), 16);
		return new Color(i);
	}
