FileReader in Java

The FileReader class is used to create a character based stream that reads from file. The FileReader class is inherited from InputStreamReader and this will throw a FileNotFoundException. 

Let us look at the following example that will open the text file and reads the content and display it.

Example:

/**
From FileReaderExample.java
*/

import java.io.FileReader;

/**

 */

public class FileReaderExample
{
    public static void main(String args[])
    {
        try
        {
            char ch[]=new char[1000];
            int size;
            FileReader fr= new FileReader("C:\\file1.txt");
            size=fr.read(ch);
            System.out.println("File Content is \n"+new String(ch,0,size));
            fr.close();

        }
        catch(Exception ex)
        {
            System.err.println(ex);
        }
    }

}

Output:
File Content is
