如何在Java中使图片不模糊

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

public class ImageLoader {
    public static BufferedImage loadImage(String filePath) throws IOException {
        File file = new File(filePath);
        return ImageIO.read(file);
    }
}

import java.awt.*;
import java.awt.image.BufferedImage;

public class ImageUtils {
    public static BufferedImage scaleImage(BufferedImage image, int width, int height) {
        Image scaledImage = image.getScaledInstance(width, height, Image.SCALE_SMOOTH);
        BufferedImage bufferedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
        Graphics2D graphics = bufferedImage.createGraphics();
        graphics.drawImage(scaledImage, 0, 0, null);
        graphics.dispose();
        return bufferedImage;
    }
}

        ImageIO.write(image, "png", file);
    }
}
