This method creates a new file in the desired path. This method checks whether the file is readable or not. Let us discuss them through this easy to comprehend table. The file class contains various methods that perform various important tasks. The methods present in File class(java.io.File):

We will see how to use them later while discussing the various file operations. The two main classes used in Character Stream are FileReader and FileWriter. Character streams usually use Byte Stream classes to implement operations. It is faster as it can take double the intake as compared to a byte stream. Character Stream takes 2 bytes of data at a time. There is also Character Stream which allows I/O operation on 16bit of Unicode data at a time. The most commonly used Input and Output Stream Classes are FileInputStream and FileOutputStream. Output Stream Classes: This stream helps to give output(Write Data) into the collection in I/O File. Input Stream Classes: This stream helps take input(Read Data) from the collection in I/O File.Ģ. The byte stream contains two stream classes, Input Stream classes and Output Stream Classes.ġ.

This stream performs an Input-output operation per 8bit of data. Thus, this stream mainly deals with 8bit of data. We know that one byte is equal to eight-bit. The byte stream deals with mainly byte data. A stream can not be called to be a data structure, rather it just takes input from the collection of I/O.Ī stream can be classified into two types: Byte Stream and Character Stream. Stream is a concept of java that pipelines a sequence of objects to obtain the desired result. Join DataFlair on Telegram!!

As this function returns integer type value has we need to use typecasting to convert it into char type. Read() method is used with BufferedReader object to read characters. We use the object of BufferedReader class to take inputs from the keyboard. Output Stream that contain print() and println() method.Ībstract class that define character stream inputĪbstract class that define character stream output Output stream that translate character to byte.

These two abstract classes have several concrete classes that handle various devices such as disk files, network connection etc. Character stream uses Unicode and therefore can be internationalized.īyte stream is defined by using two abstract class at the top of hierarchy, they are InputStream and OutputStream.

Character Stream : It provides a convenient means for handling input and output of characters.Byte Stream : It provides a convenient means for handling input and output of byte.Java encapsulates Stream under java.io package.

Streams are clean way to deal with input/output without having every part of your code understand the physical. In general, a stream means continuous flow of data. A Stream is linked to a physical layer by java I/O system to make input and output operation in java.
