How to receive images using Java?

To receive images in Java, you can use the read method of the ImageIO class. Here is a simple example:

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

public class ImageReceiver {
    public static void main(String[] args) {
        try {
            // 指定图片路径
            File imageFile = new File("path/to/image.jpg");
            
            // 使用ImageIO读取图片
            BufferedImage image = ImageIO.read(imageFile);
            
            // 处理图片
            // ...
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

In the example above, start by creating a File object by specifying the file path, then use the read method of ImageIO to read the file into a BufferedImage object. Next, you can further process this image, such as resizing, cropping, adding watermarks, etc.
