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
Programming
