Examples of java.awt.Polygon.translate()

java.awt.Polygon.translate()
Translates the vertices of the Polygon by deltaX along the x axis and by deltaY along the y axis. @param deltaX the amount to translate along the X axis @param deltaY the amount to translate along the Y axis @since 1.1

      int bottomY = (int)(.81 * r);
      
      int[] xPoints = new int[]{ 0, topX, bottomX, -bottomX, -topX };
      int[] yPoints = new int[]{ -(int)r, topY, bottomY, bottomY, topY };
      Polygon pentagon = new Polygon(xPoints, yPoints, 5);
      pentagon.translate(x+width/2, y+width/2);
  
      // draw
      g.drawPolygon(pentagon);
    }
