Reading a image file in Java

java

To read an image file in Java, you can use the ImageIO class. Here’s an example of how you can use it to read a JPEG image file:

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

import javax.imageio.ImageIO;

public class Main {
  public static void main(String[] args) {
    try {
      // Read the image file into a BufferedImage object
      BufferedImage image = ImageIO.read(new File("image.jpg"));

      // Do something with the image
      // ...
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}

This will read the image file from the same directory as the Java program and store it in a BufferedImage object. You can then use the BufferedImage object to access the pixel data and perform various operations on the image.

Note that you will need to import the necessary classes at the top of your program: java.awt.image.BufferedImage, java.io.File, and javax.imageio.ImageIO.

You can also use the ImageIO class to read other image file formats, such as PNG, GIF, and BMP. Simply replace the " image.jpg" in the File constructor with the path to the image file you want to read.
