Answer 1

Hi, Please find below the following Java applet code to draw the required circle and text on screen.

This code is writtten & compiled on Eclipse IDE.

Each segment in code has explanation on why we are using the given syntax and how we are using it.

Please find below the java code:

package applet;

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;

import javax.swing.JApplet;

public class Applet extends JApplet{
        
        public void paint(Graphics g) {
                
                /*
                 * First we are setting the size of screen as 400 x 400. 
                 * By default it will be full screen
                 */
                setSize(400, 400);
                
                /*
                 * Now, first we are drawing a circle with black color.
                 * So, first we are setting a color as black.
                 * then using function drawOval(int x, int y, int width, int height), we are drawing circle.
                 * Here (x,y) are coordinates from where we are goint to start to draw our circle with given width and height.
                 */
                g.setColor(Color.BLACK);
                g.drawOval(50,50,300,300);
                
                /*
                 * Now, we are filling the circle drawn above. We can directly use fillOval method to draw a color filled 
                 * circle, but it will not create an outline to the circle. That's why we are first drawing the circle &
                 * then filling it.
                 * 
                 * Here, first we are setting the color as yellow.
                 * Then we are filling the color with slightly less dimension then of circle. If we will take same dimension
                 * as of circle, then yellow color will override the circle boundry
                 */
                g.setColor(Color.YELLOW);
                g.fillOval(51,51,299,299);
                
                /*
                 * To write a text, first we are setting the required font and size using Font class.
                 * Then we are setting text color as Black.
                 * Now, using method drawString(int x, int y). we are writing string.
                 * (x,y) are the coordinates from where we want to start our text.
                 * In our case. it is near to center of circle.
                 */
                Font f1 = new Font("Arial",Font.BOLD,24);
                g.setFont(f1);
                g.setColor(Color.BLACK);
                g.drawString("Go", 180, 200);
                
        }
}

When you will run above code, following picture will be drawn on screen:
