示例1: xorFiles
import java.nio.channels.SeekableByteChannel; //導入方法依賴的package包/類
public static void xorFiles(SeekableByteChannel inputA, SeekableByteChannel inputB,
SeekableByteChannel outputChannel, long limit) throws IOException {
ByteBuffer aBuffer = ByteBuffer.allocateDirect(BUFFER_SIZE);
ByteBuffer bBuffer = ByteBuffer.allocateDirect(BUFFER_SIZE);
ByteBuffer outBuffer = ByteBuffer.allocateDirect(BUFFER_SIZE);
do {
if (inputA.position() == inputA.size()) inputA.position(0);
if (inputB.position() == inputB.size()) inputB.position(0);
inputA.read(aBuffer);
inputB.read(bBuffer);
aBuffer.flip();
bBuffer.flip();
int cap = min(aBuffer.remaining(), bBuffer.remaining(), outBuffer.remaining());
for (int i = 0; i < cap; i += 8) {
long a = aBuffer.getLong();
