Question

我有一只鳕鱼，但我无法完成他。我无法将sifreli [i] [j]数组转换为jpg。请帮我！！我不能把int数组写入iternet中的jpg文件我读了很多教程abaut如何将字节数组转换为jpg但我需要int [] []转换为jpg。

package odev3; 
import java.awt.image.BufferedImage; 
import java.io.*; 
import javax.imageio.*; 
import java.util.*;
    public class Odev3 {
        public static void main(String[] args) throws IOException {
        BufferedImage img=ImageIO.read(new File("xxx.jpg"));
        int [][] orijinal = new int[img.getHeight()][img.getWidth()];
                for (int i = 0; i <img.getWidth(); i++) {
                    for (int j = 0; j < img.getHeight(); j++) {
                    orijinal[i][j]= img.getRGB(i,j);
                    System.out.print(orijinal[i][j]+" ");
                }
                    System.out.println();
            }


        int [][] anahtar = new int[256][256];
        Random rnd = new Random();//burda randam bir float sayi uretyoruz 

        float sayi = rnd.nextFloat();//  Random float sayiyi bir float degiskene aktaryoruz  
        System.out.println(sayi);

        int num = (int)(sayi * 1000);//float degiskenin 0 dan sonra uc sayiyi alyoruz
        for (int i = 0;i < 256; i++){
            for(int j = 0;j < 256;j++){
               anahtar[i][j] = num%255;
               System.out.print(anahtar[i][j]+" ");
            }
            System.out.println();
        }
        int [][] sifreli = new int[256][256];
        for (int i = 0; i < 256;i++){
            for(int j = 0;j < 256;j++){
              sifreli[i][j] = orijinal[i][j]^anahtar[i][j];
               System.out.print(sifreli[i][j] + " " );
               }
               System.out.println();


            }

        }

    }

           }
           System.out.println();
        }
    BufferedImage resim = new BufferedImage(256,256,BufferedImage.TYPE_INT_RGB);  
    for (int i = 0;i<256;i++)
        for(int j = 0;j < 256;j++)
        {
            resim.setRGB(i, j, sifreli[i][j]);
        }
    File outputfile = new File("sifreli.jpg");
    ImageIO.write(resim, "jpg", outputfile);
    }

}

int array [] []到jpg Java
