I'm trying to create a random color generator

Question

//               create random color generator
                    String[]colors = {"RED", "ORANGE", "YELLOW", "GREEN", "BLUE", "INDIGO", "PURPLE"};
//               create variable to store random color
                    int mycolorint = (int)(Math.random()*7);
                    String mycolor = colors[mycolorint];
//               label axis
               StdDraw.setPenColor(StdDraw.(mycolor));
what is wrong with this code?

Answer 1

StdDraw.setPenColor(StdDraw.(mycolor));This line really doesn't make any sense. If you think about it you haven't seen any java code which includes something like "foo.(bar)" or "Foo.(bar)". The compiler wants to see identifiers either side of the dot - and identifiers don't start with a (.
I am guessing that if "RED" gets chosen from the array, then you want the label axis to useStdDraw.setPenColor(StdDraw.RED);In that case you have to set the array up a little differently.
    // create random color generator
???[]colors = {
        StdDraw.RED, StdDraw.ORANGE, StdDraw.YELLOW,
        StdDraw.GREEN, StdDraw.BLUE, StdDraw.INDIGO, StdDraw.PURPLE
    // create variable to store random color
int mycolorint = (int)(Math.random() * 7);
??? mycolor = colors[mycolorint];
    // label axis
StdDraw.setPenColor(mycolor);You will have to read the documentation for this StdDraw class to see what type StdDraw.RED etc are.
