Format of TYPE_INT_RGB and TYPE_INT_ARGB

Question

Could anyone explain for me how java stores color in TYPE_INT_RGB and TYPE_INT_ARGB ?
Do these lines of code work properly for calculating red, green and blue ?

Answer 1

The TYPE_INT_ARGB represents Color as an int (4 bytes) with alpha channel in bits 24-31, red channels in 16-23, green in 8-15 and blue in 0-7.

The TYPE_INT_RGB represents Color as an int (4 bytes) int the same way of TYPE_INT_ARGB, but the alpha channel is ignored (or the bits 24-31 are 0).

Look the javadoc of java.awt.Color and java.awt.image.BufferedImage.
