Below programs illustrate close() method in BufferedReader class in IO package:

Program 1: Assume the existence of the file “c:/demo.txt”.




// Java program to illustrate
// BufferedReader close() method
  
import java.io.*;
public class GFG {
    public static void main(String[] args)
        throws IOException
    {
  
        // Read stream file 'demo.txt'
        // containing text "GEEKSFORGEEKS"
        FileReader fileReader
            = new FileReader(
                "c:/demo.txt");
  
        // Convert fileReader to
        // bufferedReader
        BufferedReader buffReader
            = new BufferedReader(
                fileReader);
  
        // Call read() method
        while (buffReader.ready()) {
            System.out.print(
                (char)buffReader.read());
        }
  
        // Call close() method
        buffReader.close();
    }
}
Input:
Output:

Program 2: Assume the existence of the file “c:/demo.txt”.

            FileReader fileReader
                = new FileReader(
                    "c:/demo.txt");
  
            // Convert fileReader to
            // bufferedReader
            BufferedReader buffReader
                = new BufferedReader(
                    fileReader);
  
            // Call close() method
            buffReader.close();
  
            // Call read() method
            System.out.print(
                (char)buffReader.read());
        }
        catch (IOException e) {
