(Last Updated On: April 2, 2021)

Java Color class:

Java Color Class- There are situations when you need to set the foreground and background colors while designing an application in the Java. The Color class is utilized to encapsulate colors in the default sRGB”Standard Red, Green, and Blue” color space or colors in self-assertive color spaces recognized by a ColorSpace. Each color has a verifiable alpha value of 1.0 or an explicit one gave in the constructor. The alpha value defines the transparency of a color and can be spoken to by a float value in the range 0.0 – 1.0 or 0 – 255. An alpha value of 1.0 or 255 implies that the color is totally opaque and an alpha value of 0 or 0.0 implies that the color is totally transparent. While constructing a Color with an explicit alpha or getting the color/alpha components of a Color, the color components are never premultiplied by the alpha segment.

public Color (int r, int g, int b)

creates a java color class object according to the specified RGB values.

public color (float r, float g, float b)

creates a java color class object according to the specified RGB values are used.

 The float RGB values ​​in each case ​​can be determined by 255. To simplify the use of Standard colors the constants in the Color class (final class variables) BLACK, BLUE, CYAN, DARK_GRAY, GRAY, GREEN, LIGHT_GRAY, MAGENTA, ORANGE, PINK, RED, WHITE and YELLOW the corresponding commonly used color class provided. For example, if we use the java color class and we need yellow, we do not need a color object with RGB values ​​255, 255 and generate 0 (it is well known, yellow is created by mixing red and green), you can use the prefabricated Color.YELLOW object directly.

Our program example

Which inherits from JLabel and has a constructor that supports in addition to the labeling, the foreground and background color of the label gets passed. Note that a label is standard not opaque, i.e. transparent. Therefore we need to call the method setOpaque.
