The method draws a line from (x1, y1) to (x2, y2). It can be used as:

g.drawLine(10,10,50,10);

For drawing rectangle, the Graphics class provides method as:

void drawRect(int top, int left, int width, int bottom);

For example, g.drawRect(20, 20, 120, 50);

The method draws a rectangle whose top left coordinate is given as (20, 20), width 120 and height 50.

The following is another example:

int w = this.getSize().width-1;

int h = this.getSize().height-1;

g.drawRect(0, 0, w, h);

Remember that getSize(). width is the width of the applet and getSize(). height is the height.
