Answer 1

Java code:

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

public class FillOvalExample extends Applet { // extends Applet class
   public void paint(Graphics g) {

       g.setColor(Color.yellow); // set yellow color for circle
       g.fillOval(100, 100, 80, 80); // draw fillOval
       g.setColor(Color.black); // set black color for text "go"
       Font f1 = new Font("Arial", Font.BOLD, 24); // Create Font object with Arial font,bold and size 24
       g.setFont(f1); // set the font
       g.drawString("GO", 122, 146); // write go text

   }
}
Sample Output:

Explanation:

1. Applet has fillOval to draw the circle with filled color. See the syntax below,

fillOval

public abstract void fillOval(int x,
                              int y,
                              int width,
                              int height)

Fills an oval bounded by the specified rectangle with the current color.

Parameters:

x - the x coordinate of the upper left corner of the oval to be filled.

y - the y coordinate of the upper left corner of the oval to be filled.

width - the width of the oval to be filled.

height - the height of the oval to be filled.

2. Applet has drawString method to print text in applet window. See the syntax below,

drawString

public abstract void drawString(String str,
                                int x,
                                int y)

Draws the text given by the specified string, using this graphics context's current font and color. The baseline of the leftmost character is at position (x, y) in this graphics context's coordinate system.

Parameters:

str - the string to be drawn.

x - the x coordinate.

y - the y coordinate.
