Cubic Diagram In Java
Introduction
In this section, you will learn how to create
Cubic diagram. The Java2D API provides you several classes that defines
common Geometry object as a coordinate component. The Java Drawing program
depends on the Java2D API class, and this class is support by the "java.awt.geom"
package.
Program Description:
In this program, We are using CubicCurve2D class
for cubic curve component. The CubicCurve2D class creates a cubic diagram. The
CubicCurve2D class also implements the shape interface. We are going to use cubicCurve2D Class
to define a cubic parameter as a (x ,y) coordinate and this class
is only the abstract superclass for all objects which is stored in a 2D cubic curve segment.
In this program we are passing parameter like
(x1, y1, ctrlx1 , ctrly1, ctrlx2, ctrly2, x2, y2) as a coordinate
space. The parameter are defined to set cubic diagram point x-axis and y-axis
direction and the ctrlx1 or ctrly1 sets the x and y axis. All the parameters are
explained below :
x1- The x1 point is the x coordinate used to set the start point of this cubicCurve2D
y1- A y1point is the used for y coordinate to set the start point of this cubicCurve2D
ctrlx1- The ctrl x coordinate is used to set the first control point of this cubicCurve2D
ctrl y1- A ctrl y coordinate is used to set the first control point of this cubicCurve2D
ctrlx2- the ctrl x coordinate to set the second control point of this
cubicCurve2D.
ctrly2- The ctrl y coordinate is used to set the
second control point of this CubicCurve2D
x2- A point is the x coordinate used to set the second point of this
CubicCurve2D
y2- A point is the y coordinate used to set the second point of this
cubicCurve2D.
Here is the code of this program:
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
public class Cubic extends Frame{
Stroke drawingStroke = new BasicStroke(4);
CubicCurve2D cubic= new CubicCurve2D.Double(40,150, 40, 05, 300, 350, 300, 180);
public void paint(Graphics g){
Graphics2D ga = (Graphics2D)g;
ga.setStroke(drawingStroke);
ga.draw(cubic);
}
public static void main(String args[]){
Frame frame = new Cubic();
frame.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent we){
System.exit(0);
}
});
frame.setSize(310, 300);
frame.setVisible(true);
}
}
