What does getInputStream return?
The getInputStream() returns an input stream for reading bytes from this socket.
What does the read () method of InputStream return when an attempt is made to read at the end of the stream?
read. Reads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to 255 . If no byte is available because the end of the stream has been reached, the value -1 is returned.
Is InputStream class abstract?
An InputStream is the abstract, but the concrete class (the one actually referenced by System.in ) can be any subclass of InputStream, including an anonymous class. Some subclasses listed in the javadoc for InputStream include: AudioInputStream. ByteArrayInputStream.
Which of the following methods is used to get a string value from an input stream?
InputStream inputstream = new FileInputStream(“c:\\data\\input-text. txt”); byte[] data = new byte[1024]; int bytesRead = inputstream. read(data); while(bytesRead != -1) { doSomethingWithData(data, bytesRead); bytesRead = inputstream.
What is the use of getInputStream in Java?
getInputStream() method gets the input stream of the subprocess. The stream obtains data piped from the standard output stream of the process represented by this Process object.
What is DataInputStream class in Java?
Introduction. The Java.io.DataInputStream class lets an application read primitive Java data types from an underlying input stream in a machine-independent way.Following are the important points about DataInputStream − An application uses a data output stream to write data that can later be read by a data input stream.
Which method of InputStream class reads one byte and returns an int representation of that byte?
read() method
The bytes read by read() method are returned as int. If len is zero, then no bytes are read and 0 is returned; otherwise, there is an attempt to read at least one byte.
Which method in InputStream can be used in place of calling skip ()?
The java. io. InputStream. reset() method skips over and discards n bytes of data from this input stream.
What is getInputStream in Java?
Which method is used bytes from InputStream?
Method Summary
| Modifier and Type | Method and Description |
|---|---|
| int | read(byte[] b) Reads some number of bytes from the input stream and stores them into the buffer array b . |
| int | read(byte[] b, int off, int len) Reads up to len bytes of data from the input stream into an array of bytes. |
Which of the following methods of input stream is used to read integers?
DataInputStream readInt() method in Java with Examples The readInt() method of DataInputStream class in Java is used to read four input bytes and returns a integer value. This method reads the next four bytes from the input stream and interprets it into integer type and returns.
Is Getinputstream blocking?
This is because the ObjectInputStream(InputStream in) -constructor is a blocking-call if the inputStream is empty. This constructor will block until the corresponding ObjectOutputStream has written and flushed the header.
