java.util.zip.InflaterOutputStream write(byte[] b, int off, int len)方法 示例

下面的例子展示了 java.util.zip.InflaterOutputStream.write(byte[] b, int off, int len) 方法的用法。

package com.yiidian;

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.util.Arrays;
import java.util.zip.DataFormatException;
import java.util.zip.DeflaterOutputStream;
import java.util.zip.InflaterOutputStream;

public class InflaterOutputStreamDemo {

   public static void main(String[] args) throws DataFormatException, IOException {
      String message = "Welcome to Yiidian.com;"
         +"Welcome to Yiidian.com;"
         +"Welcome to Yiidian.com;"
         +"Welcome to Yiidian.com;"
         +"Welcome to Yiidian.com;"
         +"Welcome to Yiidian.com;"
         +"Welcome to Yiidian.com;"
         +"Welcome to Yiidian.com;"
         +"Welcome to Yiidian.com;"
         +"Welcome to Yiidian.com;";
      System.out.println("Original Message length : " + message.length());
      byte[] input = message.getBytes("UTF-8");

      // Compress the bytes
      ByteArrayOutputStream arrayOutputStream = new ByteArrayOutputStream();
      DeflaterOutputStream outputStream = new DeflaterOutputStream(arrayOutputStream);
      outputStream.write(input);
      outputStream.close();

      //Read and decompress the data
      InflaterOutputStream inflaterOutputStream = null;
      ByteArrayOutputStream decompressedOutputStream = null;
      decompressedOutputStream = new ByteArrayOutputStream();
      inflaterOutputStream = new InflaterOutputStream(decompressedOutputStream);
      byte[] output = arrayOutputStream.toByteArray();
      inflaterOutputStream.write(output,0,output.length);
      inflaterOutputStream.flush();
      inflaterOutputStream.close();

      //Should hold the original (reconstructed) data
      byte[] result = Arrays.copyOf(decompressedOutputStream.toByteArray(), 300);

      // Decode the bytes into a String
      message = new String(result, "UTF-8");
    
      System.out.println("UnCompressed Message length : " + message.length());
   }
}

输出结果为:
