BufferedWriter close() in Java

close(): This method is available in the java.io.BufferedWriter class of Java.

Syntax:

void java.io.BufferedWriter.close() throws IOException

This method closes the stream, flushing it first. Once the stream has been closed, further write() or flush() invocations will cause an IOException to be thrown.

Note:

Closing a previously closed stream has no effect.

Parameters: NA

Returns: NA

Throws:

IOException - If an I/O error occurs

Approach

Java

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;

public class BufferedWriterclose {
    public static void main(String[] args) throws IOException {

        FileWriter fileWriter = 
                new FileWriter("D:\\hello.txt");
        BufferedWriter bufferedWriter = 
                     new BufferedWriter(fileWriter);

        bufferedWriter.close();
        System.out.println("Successfully closed the write buffer");
    }
}

Output:

Successfully closed the write buffer
