int array [] [] zu jpg Java

Question

Ich habe einen Kabeljau, aber ich kann ihn nicht beenden. Ich kann das sifreli [i] [j] -Array nicht in jpg konvertieren. Bitte hilf mir!! Ich kann Int Array zu JPG-Datei in Inetnet nicht schreiben Ich lese viele Tutorialaut wie man Byte-Array in JPG konvertieren, aber ich brauche int [] [] in JPG konvertieren.

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(); 


      } 

     } 

    }
