Question

Write a simple java program that produces any text art ("ASCII art") picture. Your program can produce any picture you like, with the following restrictions:
• The picture should consist of between 3 and 200 lines of output, with no more than 100 characters per line.
• The code must use at least one for loop or static method but should not contain infinite loops.

Answer 1

SOLUTION:

The following is an example of Simple ASCII art using Java Programming, that prints a text using ASCII character.

PROGRAM

import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.IOException;

public class AsciiArt {

    public static void main(String[] args) throws IOException {
//      Setting The Width and Height of the ASCII Image
        int width = 100;
        int height = 100;
//        Setting the Image and Graphics Property
        BufferedImage img = new BufferedImage(width, height, BufferedImage.TYPE_BYTE_BINARY);
        Graphics g = img.getGraphics();
        g.setFont(new Font("Arial", Font.PLAIN, 28));
//        Setting the Graphics2D property to control the image co-ordinates
        Graphics2D graphics = (Graphics2D) g;
        graphics.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
//        Positioning the Output on screen
        graphics.drawString("PEACE", 10, 30);

        for (int y = 0; y < height; y++) {
//              StringBuilder Class is used to append data of any type
            StringBuilder s = new StringBuilder();
            for (int x = 0; x < width; x++)
//              Check for color pixel value match to include a space or ASCII symbol
                s.append(img.getRGB(x, y) == -16777216 ? " " : "#");
            if (s.toString().trim().isEmpty()) 
                continue;
            System.out.println(s);
        }

    }

}

SCREENSHOT

OUTPUT

NOTE:

1. The program uses the BufferedImage class to manipulate image data.
2. The Graphics class is the super class for drawing to the screen.
3. The Graphics2D class provides control over the image co-ordinates.
4. The StringBuilder Class is used to handle changing sequence of characters.

Hope this helps.
