如何在java/android中将JPG图像转换为字符串

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.Base64;

public class ImageToBase64 {
    public static void main(String[] args) {
        try {
            File file = new File("path/to/your/image.jpg");
            FileInputStream fileInputStreamReader = new FileInputStream(file);
            byte[] bytes = new byte[(int) file.length()];
            fileInputStreamReader.read(bytes);
            String encodedImage = Base64.getEncoder().encodeToString(bytes);
            System.out.println(encodedImage);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
