Convert Zip To EXE
In this example we are going to convert a zipped file
into exe.
To convert a Zip file into .exe file pass the name of a zip
file using command line arguments. Use FileInputStream to take the zipped file
as input. Read the file from the system, unzip the file and store the data of this file into a byte array.
Create
another file with .exe extension. Write the byte formatted data of the unzip
file into .exe file.
Create FileOutputStream object pass the
name of file with .exe extension for creating an exe file. ZipInputStream
allows modification on zipped (or unzipped) file. Use getNextEntry() method
to set the entry point of the zip
file. Create an array of bytes which stores the data of
unzipped file and finally write the data into exe file.
Here is the code of the program :
import java.io.*;
import java.awt.*;
import com.lowagie.text.*;
import com.lowagie.text.pdf.*;
import java.io.*;
import java.util.zip.*;
public class ZipToEXE
{
public static void main(String arg[])throws Exception
{
OutputStream out=new FileOutputStream
("pdfFile.exe");
ZipInputStream zip = new ZipInputStream
(new BufferedInputStream(new FileInputStream(arg[0])));
ZipEntry entry;
while((entry = zip.getNextEntry()) != null)
{
byte data[]=new byte[1024];
int count;
while((count=zip.read(data,0,1024))!=-1)
{
out.write(data,0,count);
}
}
out.flush();
out.close();
}
}
