2. Writing text to character stream

• Class java.io.BufferedWriter extends the java.io.Writer class.

• BufferedWriter implements buffered output of character streams

• java.io.PrintWriter adds character formatting for primitive types and Strings

• FileWriter implements low-level writing of character files

  
  import java.io.*;
  import java.nio.file.*;
  
  public class TextOutputDemo
  {
      public static void main(String[] args)
      {
          // Get a Path object for the file
          Path booksPath = Paths.get( "C:/myfiles/dummy.txt" );
          File booksFile = booksPath.toFile();
          //Write data to the file
          try
          {
              PrintWriter outp = new PrintWriter( // output formatting functionality
                                 new BufferedWriter( // implements stream buffer for character output
                                 new FileWriter(booksFile))); // basic writing of character files
              // character output:
              outp.println("book\tBeginning Java Programming\t49.50");
              outp.close();
          }
          catch (IOException e)
          {
              System.out.println(e);
          }
      }
  }//class TextOutputDemo
  
  

• Note that File objects are not files! The File class keeps metadata describing either file or directory, useful when working with files and directories of the file system.
