I'm totally lost with this one........

Question

i is an int with the value 778899
return new Color((i >> 16) & 0xFF, (i >> 8) & 0xFF, i & 0xFF);
When I run this through a debugger and step into this line, the 3 parameters in the constructor of the Color object contains the values 11, 226 and 147.
I don't understand what the code above is actually doing hence the reason why I don't understand how the color object gets these values.
Can someone explain this one. I've had a look about but no luck so far.

Answer 1

A color is expressed by a 24bit RGB value, which describes the Red, Green and Blue component. Each component is 1 byte (8 bit) large. So you can express a color as an hexidecimal number in the form 0xRRGGBB.
Take your decimal number 778899. In hexadecimal, this is 0x0BE293. So, I'll do it step by step
1) extract Red component: 0x0BE293 >> 16 = 0x00000B & 0xFF = 0x0B = 11 decimal
2) extract Green component: 0x0BE293 >> 8 = 0x000BE2 & 0xFF = 0xE2 = 226 decimal
3) extract Blue component: 0x0BE293 & 0xFF = 0x93 = 147 decimal
These are the three values that are passed to the Color constructor.
Hope it helps,
