I have not been learning Java for too long so forgive me, but I've been asked to make an applet and one of its basic functions is to allow a user to enter into a text box and for the applet to display what they write, in any case of my 2 initials (G,P) the program should instead of writing this character, fill a polygon of it.
Obviously I can't make this polygon in the same coord's everytime, so i have used a method I thought should work, which is to create variables for the first point and then get the applet to receive the coordinates of the character (through a for loop) and then display the polygon, the main problem I'm having is that the polygon is a separate function and it keeps saying identifier expected, to get rid of this i changed where the variables xpoints, ypoints and npoints are initialized and they are no longer global. but now i get like 60 errors saying not a statement (in the polygon function) and ";" expected. any help??
