Please note that it is necessary for objects to implement Serializable for ObjectOutputStream to write them to a destination. Then we discussed some of the sub-classes of OutputStream available in Java. A particular implementation of OutputStream may choose to buffer previously written bytes to optimize, but a call to flush makes it write to the destination immediately. The resulting bytes are accumulated in a buffer before being written to the underlying output stream.
PipedOutputStream can write data which a connected PipedInputStream can read. If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive. BufferedOutputStream writes data to a buffer instead which is flushed to the destination less often, when the buffer gets full, or the method flush is called.
Java FileOutputStream specifying encoding FileWriter class, which is a Java convenience class for writing character files, has a serious limitation: it uses the default encoding and does not allow us to explicitly specify the encoding. This abstract class is the superclass of all classes representing an output stream of bytes. Then we have stored a string in it with the help of write method. Alternatively, we can do this later by using a method provided in PipedOutputStream called connect. The important thing to note here is that the method close has practically no effect. A file output stream is an output stream for writing data to a File or to a FileDescriptor. Java FileOutputStream append to file With FileOutputStream it is possible to append data to a file.
Java Program to Convert OutputStream to String - The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.
An OutputStreamWriter is a bridge from character streams to byte streams: Characters written to it are encoded into bytes using a specified. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted. Each invocation of a write method causes the encoding converter to be invoked on the given character s. The resulting bytes are accumulated in a buffer before java outputstream to string written to the underlying output stream. The size of this buffer may be specified, but by default it is large enough for most purposes. Note that the characters passed to the write methods are not buffered. For top efficiency, consider wrapping an OutputStreamWriter within a BufferedWriter so as to avoid frequent converter invocations. A malformed surrogate element is a high surrogate that is not followed by a low surrogate or a low surrogate that is not preceded by a high surrogate. This class always replaces malformed surrogate elements and unmappable character sequences with the charset's default substitution sequence. The class should be used when more control over the encoding process is required. If the encoding has an historical name then that name is returned; otherwise the encoding's canonical name is returned. java outputstream to string If this instance was created with the constructor then the returned name, being unique for the encoding, may differ from the name passed to the constructor. This method may return null if the stream has been closed. Closing a previously closed stream has no effect.
