public static void main(String args[]) throws Exception

{

FileInputStream fin=new FileInputStream("i1.bmp");

DeflaterOutputStream dout=new DeflaterOutputStream(new FileOutputStream("i1.zip"));

int b;

while((b=fin.read())!=-1)

dout.write(b);

fin.close();

dout.close();

File f1=new File("i1.bmp");

File f2=new File("i1.zip");

System.out.println("Before :"+f1.length());

System.out.println("After :"+f2.length());
