Exception: This method throws IOException if an I/O error occurs.
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”.
// Java program to illustrate// BufferedReader close() method import java.io.*;public class GFG { public static void main(String[] args) throws IOException { try { // 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 close() method buffReader.close(); // Call read() method System.out.print( (char)buffReader.read()); } catch (IOException e) { // Exception is thrown System.out.println( "BufferedReader is closed"); } }} |
