Java Drawing Arcs

What is Arc?

Arc is a part of curve or a part of the circumference of a circle.

If a circle is not completed then we can say that it is an ARC.

Java applet has drawArc() method to draw arc. It has 6 arguments.

Syntax

g.drawArc(int x,int y,int width,int height, int start_angle,int sweep_angle);

Explanation

• x,y - It denotes the x,y coordinate of a center of arc.
• width,height - It denotes the arc's width and height same as Circle and Ellipse.
• start_angle - start angle starts from 0 to 360 value and rotates in anticlockwise direction while increasing value.
• sweep_angle - This value starts from 0 to 360. where value should be less than 360 to see an ARC. otherwise oval (complete circle)will be displayed.

Example

import java.awt.*;
import java.applet.*;
/* <applet code="DrawArcEx.class" width=300 height=300>
</applet> */

public class DrawArcEx extends Applet
{	
	public void paint(Graphics g)
	{
		g.drawArc(30, 30, 100, 60,0,180);
	}
}
