1. 阻塞I/O通信模型 假如现在你对阻塞I/O已有了一定了解,我们知道阻塞I/O在调用InputStream.read()方法时是阻塞的,它会一直等到数据到来时(或超时)才会返回;同样,在调用ServerSocket.accept()方法时,也会一直阻塞到有客户端连接才会返回,每个客户端连接过来后,服务端都会启动一个线程去处理该客户端的请求。阻塞I...

AByteArrayInputStreamcontains an internal buffer that contains bytes that may be read from the stream. An internal counter keeps track of the next byte to be supplied by thereadmethod. Closing aByteArrayInputStreamhas no effect. The methods in this class can be called after the...
With less to worry about, application developers can concentrate on program logic and correctness rather than memory management, which should create less "buggy" code. This benefit is sometimes understated; it is very important. I am quite sure that there are other advantages that I can't even...
This class also contains a static factory that allows arrays to be viewed as lists. The methods in this class all throw a NullPointerException, if the specified array reference is null, except where noted. The documentation for the methods contained in this class includes briefs description ...
