BufferedWriter Class close() method
- close() method is available in java.io package.
- close() method is used to flushes the characters from the stream and later will close it by using close() method.
- close() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
- close() method may throw an exception at the time of the closing stream.
IOException: This exception may throw an exception while performing input/output operation.
Syntax:
public void close();
Parameter(s):
- It does not accept any parameter.
Return value:
The return type of the method is void, it returns nothing.
Example:
// Java program to demonstrate the example
// of void close() method of
// BufferedWriter
import java.io.*;
public class CloseBR {
public static void main(String[] args) {
try {
// Instantiates StringWriter
StringWriter str_w = new StringWriter();
// Instantiates BufferedWriter
BufferedWriter buff_w = new BufferedWriter(str_w);
// Append "Hello" in buff_with the
// help of append()
buff_w.append("Hello...");
// Close the stream and free
// system resources linked with
// this stream buff_w
buff_w.close();
// we can't perform append() on
// buff_w because this stream is
// already closed
buff_w.append("World!!!");
// Read Buffer
System.out.println("" + str_w.getBuffer());
} catch (IOException ex) {
System.out.println("buff_str: " + ex.getMessage());
}
}
}
Output
buff_str: Stream closed
