BufferedWriter Class newLine() method

• newLine() method is available in java.io package.
• newLine() method” is responsible for the new line to the buffered writer stream.
• newLine() 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.
• newLine() method” may throw an exception at the time of reading a new line.
  IOException: This exception may throw an exception while performing input/output operation.

Syntax:

    public Writer newLine();

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 newline() method of
// BufferedWriter

import java.io.*;

public class NewLineBW {
    public static void main(String[] args) {
        String str = "Java Programming";
        try {
            // Instantiates StringWriter
            StringWriter str_w = new StringWriter();

            // Instantiates BufferedWriter
            BufferedWriter buff_w = new BufferedWriter(str_w);

            // Write"Hello" in buff_w with the
            // help of write() it writes hello
            // starting at 0 and ending at 4
            buff_w.write(str, 0, 4);

            // It insert a new line by using
            // newLine()
            buff_w.newLine();

            // Write"Programming" in buff_w with the
            // help of write() it writes Programming
            // starting at 5 and ending at 15
            buff_w.write(str, 5, str.length() - 5);

            // It flushes the characters
            // from buff_w to char or byte
            // stream
            buff_w.flush();

            // Read Buffer
            System.out.println("str_w.getBuffer():" + str_w.getBuffer());
            buff_w.close();
        } catch (IOException ex) {
            System.out.println("buff_w: " + ex.getMessage());
        }
    }
}

Output

str_w.getBuffer():Java
