Java Deflater getBytesRead()用法及代码示例

// 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[])

        // deflater 
        Deflater d = new Deflater(); 
  
        // get the text 
        String pattern = "GeeksforGeeks", 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)

        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());
