Help me!

Hello, i want to know how to open an image in java? For example, I already have an image .jpg, and i need to open it in java so that i can do the image processing. Anybody can help me?

Have a look at the ImageIO class; it has methods that can read image files and create a BufferedImage out of them. You can also try to use the ImageIcon class ...

kind regards,

Jos

I have try this coding, but i can't open the image. I don't know why.

import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO;

File file = new File("sign.jpg");
BufferedImage img;
img = ImageIO.read(file);

Maybe your program runs in a directory different from where your sign.jpg file is stored; try to use an absolute path name, e.g. "c:/usr/foo/sign.jpg". If you want to see where your program is running, add the following line:

System.out.println(System.getProperty("user.dir"));

kind regards,

Jos

Where is your class?
Where is your methods?

[aelynne]

class? method? I'm sorry but I have zero knowledge about java.

class? method? I'm sorry but I have zero knowledge about java.

Java is not Basic; in Java all you can do is define classes and/or interfaces; inside those classes you can define methods and inside those methods you can have statements; better read a textbook first before you try to code anything.
