How To Create Exe File In Java?

I know how to write exe files in 256 byte code but I'm not share if I trust you I will show you how to write bmp pictures in javahow to write a pictur I had a hard time I did lots of reverse engineering and hacking to figure out how to write a picture in pure computer codeAll a computer understands is numbers lolOffset   Size   Hex Value   Value Description42 4D "BM"   Magic Number (unsigned integer 66, 77)46 00 00 00   70 Bytes  Size of the BMP file00 00 Unused   Application Specific00 00 Unused   Application Specific36 00 00 00   54 bytes  The offset where the bitmap data (pixels) can be found.28 00 00 00   40 bytes  The number of bytes in the header (from this point).02 00 00 00   2 pixels  The width of the bitmap in pixels02 00 00 00   2 pixels  The height of the bitmap in pixels01 00 1 plane Number of colour planes being used.18 00 24 bits The number of bits/pixel.00 00 00 00   0   BI_RGB, No compression used10 00 00 00   16 bytes  The size of the raw BMP data (after this header)13 0B 00 00   2,835 pixels/meter  The horizontal resolution of the image13 0B 00 00   2,835 pixels/meter  The vertical resolution of the image00 00 00 00   0 colours  Number of colours in the palette00 00 00 00   0 important colours  Means all colours are importantStart of Bitmap Data00 00 FF  0 0 255 Red, Pixel (0,1)FF FF FF  255 255 255   White, Pixel (1,1)00 00 0 0  Padding for 4 byte alignment (Could be a value other than zero)FF 00 00  255 0 0 Blue, Pixel (0,0)00 FF 00  0 255 0 Green, Pixel (1,0)00 00 0 0  Padding for 4 byte alignment (Could be a value other than zeroIf you want to know more about alignment paddingIts to do with the width of your pictureLike this 5 divided 4 = 1.25 is your padding your have .25 which is 00Now remember this .25 is 00 .5 is 0000 .75 is 000000 and if 4 goes right dead on you don't need any padding or 0's after each line of coloursA bmp is written from the bottom up left to rightThe size of the raw BMP data is the Start of Bitmap Data for each set of 2 numbers it counts as 1 bite there's 16 bytes of Bitmap Data on this pictureThe offset where the bitmap data (pixels) can be found. This means how many bytes from the start of the file to where you put your bitmap dataSize of the BMP file this can be calculated by every 2 sets of numbers in the file add them together and you have the picture size in bytesA bmp is backwards in red green blue its blue green red because its how stuff is put in a computer files are mostly read backwards on computer because first number in is the last one out28 00 00 00 is how far it has to go to get to the Bitmap Data you even include this 28 00 00 00 string as 4 bytes all the way to the Bitmap Data witch is mostly 40 bytesHeres a sample code 424D AE000000 0000 0000 36000000 28000000 06000000 06000000 0100 1800 00000000 78000000 130B0000 130B0000 00000000 00000000 FFFF00 FFFF00 FFFF00 FF0000 FF0000 FF0000 0000 FFFF00 FFFF00 FFFF00 FF0000 FF0000 FF0000 0000 FFFF00 FFFF00 FFFF00 FF0000 FF0000 FF0000 0000 FF0000 FF0000 FF0000 FFFF00 FFFF00 FFFF00 0000 FF0000 FF0000 FF0000 FFFF00 FFFF00 FFFF00 0000 FF0000 FF0000 FF0000 FFFF00 FFFF00 FFFF00 0000java codeimport javax.Swing.*;import java.Io.*;Public class hex{BufferedOutputStream bufferedOutput=null;Public hex(){WriteFile("424DAE0000000000000036000000280000000600000006000000010018000000000078000000130B0000130B00000000000000000000FFFF00FFFF00FFFF00FF0000FF0000FF00000000FFFF00FFFF00FFFF00FF0000FF0000FF00000000FFFF00FFFF00FFFF00FF0000FF0000FF00000000FF0000FF0000FF0000FFFF00FFFF00FFFF000000FF0000FF0000FF0000FFFF00FFFF00FFFF000000FF0000FF0000FF0000FFFF00FFFF00FFFF000000","test.Bmp");}Public static void main(String[]args){new hex();}Public void WriteFile(String hex,String f){hex=hex.Replace(" ","");Try{bufferedOutput=new BufferedOutputStream(new FileOutputStream(f));For(int loop=0;loop<=hex.Length()-1;loop=loop+2){int value=Integer.ParseInt(hex.Substring(loop,loop+2),16);BufferedOutput.Write(value);}}Catch(FileNotFoundException e){e.PrintStackTrace();}Catch(IOException ex){ex.PrintStackTrace();}Finally{try{if(bufferedOutput!=null){bufferedOutput.Flush();bufferedOutput.Close();}}catch(IOException e){e.PrintStackTrace();}}JOptionPane.ShowMessageDialog(null,"Done Writeing File");}}
