Java Deflater Output

Question

In Java, I have created a class called Writer that extends It is initialized with the followin, where bos is a ByteOutputStream:

this.internalWriter = new Writer(bos, Manager.defaultSize, new      Deflater(Deflater.DEFAULT_COMPRESSION, true));

When later I call

bos.writeTo(System.out);

Everything seems to work okay. But I noticed if I check out what bos is actually outputting by converting it to a byte array, it is always outputting these three bytes at the end of anything, and I don't know why that would occur...any ideas? This is causing problems in my compression algorithm...

Those confusing three bytes are as follows:

[-27,2,0]

Java中的Writer像对待String一样对待所有内容，因此您会看到\\r\\n\\0 ，它是DOS换行符序列，后跟字符串终止符。
