Writing data to a file using BufferedWriter class in Java
The BufferedWriter class of Java is used to write a stream of characters to the specified destination (character-output stream). It initially stores all the characters in a buffer and pushes the contents of the buffer to the destination, making the writing of characters, arrays and Strings efficient.
You can specify the required size of the buffer at the time of instantiating this class.
Example
In the following Java program, we are trying to print a line on the console (Standard Output Stream). Here we are invoking the write() method by passing the required String.
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.OutputStreamWriter;
public class BufferedWriterExample {
public static void main(String args[]) throws IOException {
//Instantiating the OutputStreamWriter class
OutputStreamWriter out = new OutputStreamWriter(System.out);
//Instantiating the BufferedWriter
BufferedWriter writer = new BufferedWriter(out);
//Writing data to the console
writer.write("Hello welcome to Tutorialspoint");
writer.flush();
}
}Output
Hello welcome to Tutorialspoint
