ImageIo is a class in the Java Image I/O API, which provides a set of classes for reading and writing images. The `getWidth` method is used to retrieve the width of an image.
To use the `getWidth` method in ImageIo, you would typically first read an image using the `read` method and then obtain the width of the image using `getWidth`. Here's an example:
```java
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
public class ImageIoExample {
public static void main(String[] args) {
try {
File imageFile = new File("image.jpg");
BufferedImage image = ImageIO.read(imageFile);
int width = image.getWidth();
System.out.println("Image width: " + width);
} catch (IOException e) {
e.printStackTrace();
}
}
}
```
In this example, `image.jpg` is the path to the image file you want to read. The `getWidth` method returns the width of the image as an integer, which can then be used for further processing or display.
