Por que no exemplo CLICKME.APPLET do tutorial da sun. o metodo
filloval possui o argumento : g.fillOval(spot.x - RADIUS, spot.y - RADIUS, RADIUS * 2, RADIUS * 2);
}
Por que - RADIUS (traço RADIUS) se quando vou pesquisar na java documentation ele aparece assim:
void fillOval(int x, int y, int width, int height)
Overrides Graphics.fillOval.
ou seja 4 argumentos inteiros separados por " virgula" e nao (traço).
P :shock: odem me ajudar?
