Hi<BR> I am newbie to java and I have written a code in java that creates a window in which a line and rectangle appears. Here is the code.
import java.awt.*;<BR> public class FirstCanvase extends Canvas<BR> {<BR> public FirstCanvase()<BR> {<BR> setSize(500,500);<BR> setBackground(Color.white);<BR> }<BR> public static void main(String[] args) <BR> {<BR>
FirstCanvase FC=new FirstCanvase();<BR>
Frame f1=new Frame();<BR> f1.add(FC);<BR> f1.setSize(250,250);<BR> f1.setVisible(true);<BR> }<BR> public void paint(Graphics g)<BR> {<BR> g.setColor(Color.blue);<BR> g.drawLine(30,30,80,80);<BR> g.drawRect(50,50,100,100);<BR> }<BR> }<BR>
EVERY THING IS WORKING FINE. I GOT A WINDOW DISPLAYED WITH A LINE & RECT. BUT THE PROBLEM IS I AM UNABLE TO CLOSE THE WINDOW.
I AM USING ECLIPSE TO RUN THE PROGRAM.
WHAT CAN I DO TO SOLVE IT?

The given code draws a line and a rectangle on a swing frame using Graphics class.
import javax.swing.*;
import java.awt.*;
public class DrawLineAndRectangle{
public static void main(String[] args) {
DrawLineAndRectangle d = new DrawLineAndRectangle();
}
public DrawLineAndRectangle(){
JFrame frame = new JFrame("Drawing with Alpha");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(new MyComponent());
frame.setSize(400,400);
frame.setVisible(true);
}
public class MyComponent extends JComponent{
public void paint(Graphics g){
int height = 200;
int width = 120;
g.setColor(Color.red);
g.drawRect(10,10,180,100);
g.setColor(Color.red);
g.drawLine(250,50, 200,100);
}
}
}
