Design in Java and LOGO II
COLOR: We've already had a basic lesson on RGB values and how
to set color in JAVA. In this lesson we will look at a few more details.
There are three constructors for the Color class:
<![CDATA[
Color(int r, int g, int b);
Color(int rgb);
Color(float r, float g, float b);
]]>
You've already seen how to use the first inside a call to setColor which you
would use inside the paint method:
<![CDATA[
g.setColor(new Color(255, 0, 0));
]]>
The other real useful constructor is used like this:
<![CDATA[
g.setColor(new Color(0xff0000));
]]>
Both of these examples will set the current color to red. Using RGB values
which are encoded as HEXADECIMAL values is often easier than using decimal
values. To use a HEX value you need to start the number with "0x" in order
for the compiler (the javac program) to recognize what your intentions are.
The GIMP will provide HEX values for you and so this is all you need to know
in order to use HEX values with this constructor.
ASSIGNMENT:
Create and display the following design as an applet and as a LOGO image. Include the
code for each in two separate text areas. NOTE: You must use the Color
constructor with HEX values for at least six of your colors AND all sixteen
of your colors must be unique (although they can be different SHADES of the
same color).
