    Default Drawing a pentagon

    Hello!

    I am in my final year of High School so my knowledge about Java is fairly limited. I do not need the following for a school project, I am busy developing a program that will make use of a pentagon.
    I already have the coordinates (x ; y) of the pentagon, I just need an example of how to plot the coordinates and draw the pentagon in Java.

    Thank you for your help.

    Regards
    Zomosa

    Check out the Polygon class and the Graphics class. The API is your best friend: Java Platform SE 6

    I was afraid someone was going to link me to Java Documents. We never did the Graphics class nor any basic shape drawing due to our limited syllabus, nonetheless I will try...

    Polygon(int[] xpoints, int[] ypoints, int npoints) - Can the xpoints and ypoints be declared as Double?

    You've never worked with the Graphics class at all? How have you done your drawing previously?

    What happened when you tried?

    Note that using the Polygon class is just one way to do it. You could just use drawLine() instead, if you wanted to stick with something a bit easier to understand.

    Yes, we have not. Basically we did input from user, Graphical User Interface, arrays, matrices, write and read to and from a file, loops and array of objects.
    I googled and got some notes on StdDraw.java. They do not say what to import though, do you perhaps know? I should be able to figure it out from there, there is a few examples.

    It looks like this : StdDraw.line(0.0, 0.0, 1.0, 0.0);

    I don't know what StdDraw is. I'd recommend you read through this instead: Lesson: Performing Custom Painting (The Java™ Tutorials > Creating a GUI With JFC/Swing)
