  1. Just use the read method of the Java ImageIO class, and you can open/read images in a variety of formats (GIF, JPG, PNG) in basically one line of Java code. Here's a sample Java class that demonstrates how to read an image file. As you'll see from the example, you open and read the file in one line of code, and everything else is boilerplate
  2. Below is the complete code to read and write image file in Java: import java.io.File; //to handle the Exception import java.io.IOException; import java.awt.image.BufferedImage; //importing ImageIO class import javax.imageio.ImageIO; public class ImgRead_Write { public static void main(String[] args) throws IOException { int width = 1920; //width of the image int height = 1080; //height of the image BufferedImage image = null; File f = null; //read image try{//here D:\\Wallpaper\\img2.jpg is.
  3. To read an image from a file, you can use ImageIO.read(File) (which returns a BufferedImage). But since BufferedImage is a subclass of Image, you can do: try { File pathToFile = new File(image.png); Image image = ImageIO.read(pathToFile); } catch (IOException ex) { ex.printStackTrace();

now use File class and create an object of File class (dir) and pass the path as an argument in File(File(path)) after that all we need to create a list of Image Extensions to filter out or find. To read an .jpg file from non-relative path you could use this: BufferedImage img = null; try { img = ImageIO.read(new File(C:/ImageTest/pic2.jpg)); // eventually C:\\ImageTest\\pic2.jpg } catch (IOException e) { e.printStackTrace(); } I do not have any Java environment at the moment, so hope it works and is written correctly I am trying to retrieve a .png file type from a file share and read it as a java.io.File but I am having some trouble doing that. I am able to access the drive and print out the list of files with no issues, so I am just confused on how to read the images as a File. The code I trying to use to access the image is In Java, we can use the javax.imageio.ImageIO class to read and write an image.. 1. Read an image. Read an image from a file.
