void finish()
描述 (Description)
java.util.zip.InflaterOutputStream.finish()方法完成将压缩数据写入输出流而不关闭底层流。 将多个过滤器连续应用于同一输出流时，请使用此方法。
声明 (Declaration)
以下是java.util.zip.InflaterOutputStream.finish()方法的声明。public void finish()
throws IOException
异常 (Exceptions)IOException - 如果发生I/O错误。
例子 (Example)
以下示例显示了java.util.zip.InflaterOutputStream.finish()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 ;"
+"Welcome to ;"
+"Welcome to ;"
+"Welcome to ;"
+"Welcome to ;"
+"Welcome to ;"
+"Welcome to ;"
+"Welcome to ;"
+"Welcome to ;"
+"Welcome to ;";
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);
inflaterOutputStream.write(arrayOutputStream.toByteArray());
inflaterOutputStream.finish();
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
