使用Gzip进行简单压缩操作

public class GZIPcompress{

 public static void main(string[] args ){

   throws IOExecption 

     if (args.length ==0){

    System .out.println( "Usage : \nGZIPcompress file\n" + " tUses GZIP compress to compress " + "the file to test.gz")

 System.exit(1);

         }

    BufferedReader in = new BufferedReader(new FileReader(args[0]));

          BufferedOutputStream out = new BufferedOutputStream(new GZIPOutputStream(new FileOutputStream(""te.gz)));

          System.out.println("Writing file");

           int c ;

           while(c=in.read()!=-1)

           out.write(c);

           in.close();

           out.close();

           System.out.println(" Reading file");

   BufferedReader in2 = new BufferedReader(new InputStreamReader(new GZIPInputStream(new FileInputStream("test.gz"))));

           String s ; 

          while(s= in2.readLine()!=null) 

         System.out.println(s);        

}
