jad反编译后的代码:
public abstract class URLConnection
{
public InputStream getInputStream()
throws IOException
{
throw new UnknownServiceException("protocol doesn't support input");
}
}
根本就没用return语句，是怎么回事呢？
还有，比如
public abstract class InputStream
implements Closeable
{
public InputStream()
{
}
public abstract int read()
throws IOException;
public int read(byte abyte0[])
throws IOException
{
return read(abyte0, 0, abyte0.length);
}
}
API 说是read()“从输入流读取下一个数据字节。”这抽象方法是如何读取下一个数据字节的呢？read(byte abyte0[])又是返回一个什么样的int整数呢？
