Answer 1

Answer:

// Drawing (or printing) texts on the graphics screen:

drawString(String str, int xBaselineLeft, int yBaselineLeft);

// Drawing lines:

drawLine(int x1, int y1, int x2, int y2);

drawPolyline(int[] xPoints, int[] yPoints, int numPoint);

// Drawing primitive shapes:

drawRect(int xTopLeft, int yTopLeft, int width, int height);

drawOval(int xTopLeft, int yTopLeft, int width, int height);

drawArc(int xTopLeft, int yTopLeft, int width, int height, int startAngle, int arcAngle);

draw3DRect(int xTopLeft, int, yTopLeft, int width, int height, boolean raised);

drawRoundRect(int xTopLeft, int yTopLeft, int width, int height, int arcWidth, int arcHeight)

drawPolygon(int[] xPoints, int[] yPoints, int numPoint);

// Filling primitive shapes:

fillRect(int xTopLeft, int yTopLeft, int width, int height);

fillOval(int xTopLeft, int yTopLeft, int width, int height);

fillArc(int xTopLeft, int yTopLeft, int width, int height, int startAngle, int arcAngle);

fill3DRect(int xTopLeft, int, yTopLeft, int width, int height, boolean raised);

fillRoundRect(int xTopLeft, int yTopLeft, int width, int height, int arcWidth, int arcHeight)

fillPolygon(int[] xPoints, int[] yPoints, int numPoint);

// Drawing (or Displaying) images:

drawImage(Image img, int xTopLeft, int yTopLeft, ImageObserver obs);  // draw image with its size

drawImage(Image img, int xTopLeft, int yTopLeft, int width, int height, ImageObserver o);  // resize image on screen
