void write(byte[] b, int off, int len)
描述 (Description)
java.util.zip.InflaterOutputStream.write(byte[] b, int off, int len)方法将一个字节数组写入压缩输出流。
声明 (Declaration)
以下是java.util.zip.InflaterOutputStream.write(byte[] b, int off, int len)方法的声明。
public void write(byte[] b, int off, int len)
throws IOException
参数 (Parameters)
b - 要写入的数据。
off - 数据的起始偏移量。
len - 数据的长度。
异常 (Exceptions)
IndexOutOfBoundsException - 如果关闭“0，或者len”0，或者len“b.length - off。
IOException - 如果发生I/O错误或此流已关闭。
NullPointerException - 如果b为null。
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（byte [] b，int off，int len）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();
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());
}
}
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
