How to Create Circle In Java
Introduction:
This is a simple program of java awt. In this section,
you will learn how to create Circle Diagram. The java circle is the most
fundamental abstractions in a Java 2D in the supported java.awt.shape
package. It describes a shape. But the Java 2D definition of a shape does
not require the shape to enclose an area. The Java2D API also provides
several classes that defines common Geometric Objects.
Program Description:
In this program, you will also show that how to create
square drawing. Inside the program define a class name CircleDraw for the
circle component. There is created two types of diagrams "Circle"
and "square" for this program. Here, this program uses Ecllpise2D
that is implemented to specify eclipse float and double. double and float components
are represented for creating the square and circle in this program.
setPaint(): This class is used for filling the color.
Here is the code of this program:
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
public class CircleDraw extends Frame {
Shape circle = new Ellipse2D.Float(100.0f, 100.0f, 100.0f, 100.0f);
Shape square = new Rectangle2D.Double(100, 100,100, 100);
public void paint(Graphics g) {
Graphics2D ga = (Graphics2D)g;
ga.draw(circle);
ga.setPaint(Color.green);
ga.fill(circle);
ga.setPaint(Color.red);
ga.draw(square);
}
public static void main(String args[]) {
Frame frame = new CircleDraw();
frame.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent we){
System.exit(0);
}
});
frame.setSize(300, 250);
frame.setVisible(true);
}
}
