How to get Original value from RGB in java

Question

I create RGB from 320 number. I got following
output:

-16776896

I wrote this code

Color c=new Color(320);
System.err.println(c.getRGB());
System.out.println(c.getRed()+" "+c.getGreen()+" "+c.getBlue()+" "+c.getAlpha());
System.out.println(c.toString());

Now I want to retrive 320 value from this -16776896 . what should i do?

Answer 1

System.out.println(c.getRGB() & 0x00ffffff);

The input is bitwise OR d with 0xFF000000 in the constructor of Color . This is the inverse operation.

Actually, it is impossible to get the original value if it is negative or bigger than 16777215 .
