The newLine() method of BufferedWriter class in Java is used to separate the next line as a new line. It is used as a write separator in buffered writer stream.
Syntax:
public void newLine()
throws IOException
Parameters: This method does not accept any parameter.
Return value: This method does not return any value.
Exceptions: This method throws IOException if an I/O error occurs.
Below programs illustrate newLine() method in BufferedWriter class in IO package:
Program 1:
// Java program to illustrate// BufferedWriter newLine() method  import java.io.*;  public class GFG {    public static void main(String[] args)        throws IOException    {          // Create the string Writer        StringWriter stringWriter            = new StringWriter();          // Convert stringWriter to        // bufferedWriter        BufferedWriter buffWriter            = new BufferedWriter(                stringWriter);          // Write "A" to buffer writer        buffWriter.write(65);          // Revoke newLine() method        buffWriter.newLine();          // Write "B" to buffer writer        buffWriter.write(66);          buffWriter.flush();          System.out.println(            stringWriter.getBuffer());    }} |
Output:
A B
Program 2:
// Java program to illustrate// BufferedWriter newLine() method  import java.io.*;  public class GFG {    public static void main(String[] args)        throws IOException    {        // Create the string Writer        StringWriter stringWriter            = new StringWriter();          // Convert stringWriter to        // bufferedWriter        BufferedWriter buffWriter            = new BufferedWriter(                stringWriter);          // Write "GEEKS" to buffered writer        buffWriter.write(            "GEEKSFORGEEKS", 0, 5);          // Revoke newLine() method        buffWriter.newLine();          // Write "GEEKSFORGEEKS"        // to buffered writer        buffWriter.write(            "GEEKSFORGEEKS", 0, 13);          buffWriter.flush();          System.out.println(            stringWriter.getBuffer());    }} |
Output:
GEEKS GEEKSFORGEEKS
