Example

The following example shows the usage of java.io.BufferedReader.close() method.

package com.tutorialspoint;

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class BufferedReaderDemo {
   public static void main(String[] args) throws Exception {
      
      InputStream is = null; 
      InputStreamReader isr = null;
      BufferedReader br = null;

      try{
         // open input stream test.txt for reading purpose.
         is = new FileInputStream("c:/test.txt");
         
         // create new input stream reader
         isr = new InputStreamReader(is);
         
         // create new buffered reader
         br = new BufferedReader(isr);
         
         // releases any system resources associated with reader
         br.close();
         
         // creates error
         br.read();
         
      }catch(IOException e){
         
         // IO error
         System.out.println("The buffered reader is closed");
      }finally{
         
         // releases any system resources associated
         if(is!=null)
            is.close();
         if(isr!=null)
            isr.close();
         if(br!=null)
            br.close();
      }
   }
}

Assuming we have a text file c:/test.txt, which has the following content. This file will be used as an input for our example program:

ABCDEFGHIJKLMNOPQRSTUVWXYZ

Let us compile and run the above program, this will produce the following result:

IOException: The buffered reader is closed
