File Handling in Java Tutorial

1. Byte Streams: (Byte by Byte) The Streams that will the perform the operations Byte by Byte are called as ‘Byte Streams’. These Streams can handle any kind of data like Text, Audio, Video, Images etc. The Byte Streams are further classified into two categories.
1.1.Input Stream: These Streams are used to perform Reading operation from any resource using these Streams we can read data into an application.
Ex: File InputStream
Data InputStream etc.
1.2.OutputStream: These Streams are used to perform writing operation to any resource. These Streams can he used to send data out of the applications.
Ex: FileOutputStream
BufferedOutputStream etc.
2. Character Streams: (char by char)The Streams that perform the operation character by character are called as character Streams. These Streams can handle only text. There also called as Text Streams. The character Streams are faster then Byte Streams. The character Streams are further classified into two catagories.
2.1. Reader: These Streams are similar to Input Streams performing Reading operations from various resources.
Ex: FileReader
BufferedReader
2.2. Writer: These Streams are similar to output Streams performing writing operations on to various resources.
Ex: FileWriter
PrintWriter
All the Stream related classes are available in“java.io.package
*DataInputStream: This Stream is used to perform Reading operation from any resource.
Creation of DataInputStream
Syntax: DataInputStream dis = new DataInputStream(resource);
//pro from Read to keyboard.
import java.io.*;
class Readdemo{
public static void main(String[] args) throws IOException{
//Creating the object of DataInputStream and Connecting it to the resource.
DataInputStream dis = new DataInputStream(System.in);
//reading multiple characters and displaying then
int ch;
while((ch = dis.read())!=’$’){
System.out.println((char) ch);
}
} input.text(file)
}
