The “javax.imageio” package is used to deal with the Java image stuff. Here’s two “ImageIO” code snippet to read an image file.
1. Read from local file
File sourceimage = new File("c:\\mypic.jpg");
Image image = ImageIO.read(sourceimage);
2. Read from URL
URL url = new URL("https://mkyong.com/image/mypic.jpg");
Image image = ImageIO.read(url);
ImageIO Example
In this example, you will use ImageIO to read a file from an URL and display it in a frame.
package com.mkyong.image;
import java.awt.Image;
import java.io.IOException;
import java.net.URL;
import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class ReadImage
{
public static void main( String[] args )
{
Image image = null;
try {
URL url = new URL("https://mkyong.com/image/mypic.jpg");
image = ImageIO.read(url);
} catch (IOException e) {
e.printStackTrace();
}
JFrame frame = new JFrame();
frame.setSize(300, 300);
JLabel label = new JLabel(new ImageIcon(image));
frame.add(label);
frame.setVisible(true);
}
}

private String imagedir = “C:\”;
Not working neither
Hi, i need help, i am so desperate.
I am trying to show and image which is out of the project. Using a path like:
c:\mypic.jpg is not working for me.
My program is kind of:
private String imagedir = “C://”;
private String imageFileNames = “s02a01.jpg”;
ImageIcon icon;
icon = createImageIcon(imagedir + imageFileNames);
Can someone help me with the correct imagedir?
C:\mypic.jpg is where the image mypic with the extension of a JPEG is stored, change “C:\mypic.jpg” to the exact location of your picture
is that really you in the pic? 🙂
