The Java I/O means Java Input/Output. It is provided by the java.io package. This package has an InputStream and OutputStream. Java InputStream is defined for reading the stream, byte stream and array of byte stream.
Java I/0 Examples
What is Java I/O? The Java I/O means Java Input/Output. It is provided by the java.io
package. This package has an InputStream and OutputStream. Java InputStream is
defined for reading the stream, byte stream and array of byte stream.
Reading Text from
the Standard Input
Java provides the standard I/O facilities for reading text through
either from the file or from the keyboard on command line. This program illustrates how to use standard input to read the user input.
the Files The File class deals with the
machine dependent files in a machine-independent manner i.e. it is easier to write
platform-independent code that examines and manipulates files using the File
class. This class is available in the java.lang
Filter I/O Streams Like I/O streams, Filter streams
are also used to
manipulate the data reading from an underlying stream.. Apart from this,
it allows the user to make a chain using
multiple input stream so that, the operations that are to be applied
on this chain, may create a combine effects on
Overview of I/O Data Streams Data streams are filtered streams that perform binary
I/O operation on primitive data type values ( boolean, char, byte, short, int,
long, etc.) as well as on String values. If
you need to work with data that is not represented as bytes or characters then
you can use Data Streams.
Using a Random Access
n this section, you will learn about the Random Access File
provided by java. io package. This is a class that allows you to read
and write arbitrary bytes, text, and primitive Java data types from or
to any specified location in a file.
Making Tokens of a Java Source Code In Java, The StreamTokenizer class is used for simple
parsing of a Java source file into tokens. This class takes an input
stream, breaks up the ASCII text in a file and parses it into
"tokens". It allows the tokens to be read one at a time.
Introduction to Encoding Java programs use Unicode text internally.
It supports standard UTF-8 when reading and writing strings
through the InputStreamReader and the OutputStreamWriter.
URL file Download and Save in the Local Directory This Program file download from URL and save this Url File in the
specified directory. This program specifies the directory path where the files to
be stored as first command line argument and second command line arguments
specifies URL File to be stored.
