How to draw heart using java awt libaray?

问题

How to draw heart using java awt libaray? I am using Java AWT Libaray and I need to draw a heart for my game. How can I do this using AWT?

Here what I was thinking: may be use g.fillArc()? but then if I make two curves at top than how to make a triangle at button? Would that be g.fillPolygon()?

g.fillArc(x, y, 20,20, 60, 60); //so this will be left curve

g.fillArc(x+20, y, 20,20, 60, 60); //so right curve?

//button triangle?

I was wondering if any one is experence in awt and could show me how to do this?

Had to write this code for something I'm doing and it works well enough. Draws a triangle at x and y with the specified width and height using graphics g.

// Draw a heart.
public void drawHeart(Graphics g, int x, int y, int width, int height) {
    int[] triangleX = {
            x - 2*width/18,
            x + width + 2*width/18,
            (x - 2*width/18 + x + width + 2*width/18)/2};
    int[] triangleY = { 
            y + height - 2*height/3, 
            y + height - 2*height/3, 
            y + height };
    g.fillOval(
            x - width/12,
            y, 
            width/2 + width/6, 
            height/2); 
    g.fillOval(
            x + width/2 - width/12,
            y,
            width/2 + width/6,
            height/2);
    g.fillPolygon(triangleX, triangleY, triangleX.length);
}

//You don't really need AWT in Heart drawing here ://

public static void main(String[] args) {
       int H=7,W=7;
       for(int i=2;i<=(H+1)/2;i++){

      for(int j=0;j<W/2-i;j++){
        System.out.print(" ");
       }
    for(int k=1;k<(i+1)*2+1;k++){
    System.out.print("*");
    }

    if(i==2){
    System.out.print(" ");
    }

    for(int j=0;j<W/2-i+1;j++){
    System.out.print(" ");
    }

    for(int k=1;k<(i+1)*2+1;k++){
    if(i==(H+1)/2&&k>i+3)
    System.out.print("");
    else
    System.out.print("*");
    }
    System.out.println();

    }
    int HH=17,WW=17;
    for(int i=1;i<=HH/2;i++){

    for(int j=1;j<=i;j++){
    System.out.print(" ");
    }
    int z=WW-2*i;
    for(int k=1;k<=z;k++){
    System.out.print("*");
    }
    System.out.println();
 }
}

}
