BCSL043 December 2015 Set 4 Solution

Question 1- Write a Java program to create an applet to draw a circle. Set background color of the circle as red. Also write your name and roll number below the circle.

Solution -

import java.applet.*;
import java.awt.*;

public class drawcircle extends Applet 
{
public void paint(Graphics g)
{
g.setColor(Color.red);
        g.fillOval(50,50,150,150);
        g.setColor(Color.black);
        g.drawString("Name = IGNOULIA",90,220);
        g.drawString("Roll No = FSJX3543",90,240);
}
}

/*
<applet code="drawcircle.class" width="330" height="300"></applet>
*/

filename: drawcircle.java

For compiling the file type this command in cmd: javac drawcircle.java
For execution of the file use this command: appletviewer drawcircle.java

Explanation:
setColor method of graphics object is used to set the color. fillOval(int x,int y,int width,int height) method is used to draw a oval,here x and y argument of fillOval() is used to specify the x and y coordinate of oval and length,width parameter is used to specifiy the width,height of oval.
Because here we are drawing a circle height,width parameter should be equal.
