Example 1:
// Java program to describe the use// of getBytesRead() function  import java.util.zip.*;import java.io.UnsupportedEncodingException;  class GFG {    public static void main(String args[])        throws UnsupportedEncodingException    {        // deflater        Deflater d = new Deflater();          // get the text        String pattern = "Lazyroar", text = "";          // generate the text        for (int i = 0; i < 4; i++)            text += pattern;          // set the input for deflator        d.setInput(text.getBytes("UTF-8"));          // finish        d.finish();          // output bytes        byte output[] = new byte[1024];          // compress the data        int size = d.deflate(output);          // compressed String        System.out.println("Compressed String :"                           + new String(output)                           + "\n Size " + size);          // original String        System.out.println("Original String :"                           + text + "\n Size "                           + text.length());          // get the total number of        // uncompressed bytes input so far        System.out.println("Bytes Read value :"                           + d.getBytesRead());          // end        d.end();    }} |
Output:
Compressed String :x?sOM?.N?/r???q?? Size 21 Original String :LazyroarLazyroarLazyroarLazyroar Size 52 Bytes Read value :52
