Help! Array of polygons

Question

I'm trying to figure out a program for my computer science class. In short, I'm trying to use a bunch of values as points for a polygon (which by itself works just fine, it's the array that messes up) and, in a loop, create multiple instances of the polygon a given distance away.
Polygon polyx[]=new Polygon[50];
     for(int temp=0; temp<10; temp++){
polyx[temp].addPoint( xValues[0]+10*temp, yValues[0]+60*temp );
polyx[temp].addPoint( xValues[1]+10*temp, yValues[1]+60*temp );
polyx[temp].addPoint( xValues[2]+10*temp, yValues[2]+60*temp );
polyx[temp].addPoint( xValues[3]+10*temp, yValues[3]+60*temp );
polyx[temp].addPoint( xValues[4]+10*temp, yValues[4]+60*temp );
polyx[temp].addPoint( xValues[5]+10*temp, yValues[5]+60*temp );
g.drawPolygon( polyx[temp] );
g.fillPolygon(polyx[temp]);
I don't get any errors compiling, but I get runtime errors and It doesn't work.

ok, before jsalonen pulls his/her hair out screaming "do as youre told"
the advice was
"polyx[temp] = new Polygon();"
not
"Polygon polyx[temp] = new Polygon;"
this line should appear as the first line inside the temp for loop
it is needed because declaring an array (in your case of Polygon<s>) creates an array of the desired class, but fills it with null values, not the default constructor "new Object()"
also, the error you got was because your line really tries to declare an array of Polygon and has a syntax error, you cant put [temp] at this point, just [] so the compiler expects ] and got t
if you fixed that you would get an error with "new Polygon", the compiler would expect "new Polygon[int size]"
if you did that how ever you would then be declaring yet another polyx array of Polygon<s> for each iteration of the loop and your code would still not function
