Triangle Draw Method

I have trouble drawing a triangle with the draw(Graphics g) method in Java. I can draw a rectangle like so:

public void draw(Graphics g) {
    g.setColor(colorFill);
    g.fillRect(p.x, p.y, width, height);
    g.setColor(colorBorder);
    g.drawRect(p.x, p.y, width, height);
    drawHandles(g);

Where p represents "the top left corner of the shapes". How would I draw the triangle in the same manner?

Could someone give me an example for a standard triangle?

there is no command directly to draw Triangle. For Drawing of triangle we have to use the concept of lines here.

i.e, g.drawLines(Coordinates of points)

There is no direct method to draw a triangle. You can use drawPolygon() method for this. It takes three parameters in the following form: drawPolygon(int x[],int y[], int number_of_points); To draw a triangle: (Specify the x coordinates in array x and y coordinates in array y and number of points which will be equal to the elements of both the arrays.Like in triangle you will have 3 x coordinates and 3 y coordinates which means you have 3 points in total.) Suppose you want to draw the triangle using the following points:(100,50),(70,100),(130,100) Do the following inside public void paint(Graphics g):

int x[]={100,70,130};
int y[]={50,100,100};
g.drawPolygon(x,y,3);

Similarly you can draw any shape using as many points as you want.
