void write(int b)

描述 (Description)

java.util.zip.InflaterOutputStream.write(int b)方法将一个字节写入压缩输出流。 此方法将阻塞，直到可以写入字节。

声明 (Declaration)

以下是java.util.zip.InflaterOutputStream.write(int b)方法的声明。

public void write(int b)
 throws IOException

参数 (Parameters)

• b - 要写入的字节。

异常 (Exceptions)

• IOException - 如果发生I/O错误。

• ZipException - 如果发生压缩（ZIP）格式错误。

例子 (Example)

以下示例显示了java.util.zip.InflaterOutputStream.write（int b）方法的用法。

package com.iowiki;
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 iowiki.com;"
         +"Welcome to iowiki.com;"
         +"Welcome to iowiki.com;"
         +"Welcome to iowiki.com;"
         +"Welcome to iowiki.com;"
         +"Welcome to iowiki.com;"
         +"Welcome to iowiki.com;"
         +"Welcome to iowiki.com;"
         +"Welcome to iowiki.com;"
         +"Welcome to iowiki.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();
      for(int i = 0; i < output.length; i++){
         inflaterOutputStream.write(output[i]);
      }
      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());
   }
}

让我们编译并运行上面的程序，这将产生以下结果 -

Original Message length : 300
UnCompressed Message length : 300
