本文给出的代码用于比较Java中的FileOutputDemo与PrintStream类 的性能。

部分代码展示：
  public static void main(String args[])  {              
  FileOutputStream out; // declare a file output object
    PrintStream p; // declare a print stream object

try {
  // connected to "myfile.txt"
      out = new FileOutputStream("myfile.txt");
      // Connect print stream to the output stream
      p = new PrintStream( out );
      p.println ("This is written to a file");
      p.close();
    } catch (Exception e) {
      System.err.println ("Error writing to file");
    }
