Hello,
I am trying to make this pie chart program work in NetBeans 7.2.1, but it won't compile for a reason I cannot grasp....
This is the block of code that is creating issues: 

for (int i = 0; i < values.size(); i++) {
                g2d.setColor(colors.get(i));

and this is the errors I am getting from it:

method setColor in class Graphics cannot be applied to given types;
required: Color
found: Object
reason: actual argument Object cannot be converted to Color by method invocation conversion

Can someone please tell me what is happening here, because this program runs perfectly from the desktop, in the command prompt, but I need it to be in Net5Beans so that I can use it for another program I am working on??
PLEASE HELP ME!!

Just from few lines one reason could be that "colors.get(i)" is object that you may have to explicitly cast as Color
g2d.setColor((Color)colors.get(i));

@rizvisa1,
I figured that as well, but what was confusing me was that this EXACT code ran fine when I compiled and ran it from the command prompt, but had issues when I sposed the code into NetBeans, and that was freaking me out a bit??

I don't believe so, I have the latest run-time environment installed, if I am not mistaken....

Since you said code works in desktop and only in IDE it is causing issue, I dont think any thing is wrong with code. Some how IDE is corrupted to some extent or using different java version. See if this helps

g2d.setColor((Color)colors.get(i));

Try this.....
This is called downcasting
