Hi all, I am trying to learn my Java, and I am using my terminal in my mac to run my Java code. It compiles but when I run it I get the following error message:

-bash-3.00$ java Bifurcationlo
Exception in thread "main" java.awt.HeadlessException: 
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
        at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:159)
        at java.awt.Window.<init>(Window.java:406)
        at java.awt.Frame.<init>(Frame.java:402)
        at java.awt.Frame.<init>(Frame.java:367)
        at Bifurcationlo.<init>(Bifurcationlo.java:21)
        at Bifurcationlo.main(Bifurcationlo.java:83)

I am guessing I need something to display this plot using Java. Any tips out there. Also does anyone knows a good tutorial to how to use the drawString method. Thanks

G :confused:
