Character Oriented

Author: Ravi Poswal

Character-oriented is the user input and output of 16-byte Unicode characters. It is used to read and write the character. There are many sub-classes, but the most common classes are:- Reader, Writer BufferedReader, FileReader, FileWriter, InputStreamReader, etc.

a. FileReader classes: The abstract class reads characters from files using the read() method.

Syntax:-

FileReader reader=new FileReader(“file.txt”);

reader.read();

b. FileWriter classes:-It is the abstract class that writes a character into files using the write() method.

Syntax:-

FileWriter out=new FileWriter(“ouput.txt”);

                                        out.write();

c. BufferedReader classes:- It reads characters and strings from the input stream. This class is based on buffering.

Syntax:

BufferReader b=new BufferReader(new InputStreamReader(System.in));

                           b.readLine();

Code Example

import java.io.*;  
public class Display {  
    public static void main(String[] args) {  
        try {  
            Writer w = new FileWriter("infile.txt");  
            String content = "I love my india";  
            w.write(content);  
            w.close();  
        System.out.println("complete");  
        }
 catch (IOException e) {  
            e.printStackTrace();  
        }    }  }
