Is there really a difference between referencing and creating new object from reference of PrintStream?

Question

Below are the two ways of getting reference of the PrintStream object:

class Ex1 {
    public static void printEx() {
        //line 1: Direct Reference
        PrintStream ps1 = System.out;
        //line 2: Passing Reference as argument in constructor
        PrintStream ps2 = new PrintStream(System.out);
    }
}

Is there really a significant difference between those two lines in terms of usage or can (or should) it be used interchangeably?

Answer 1

Take as a reference this page;

import java.io.*;
public class SystemOutPrintlnDemo
{
  public static void main(String[] args) 
  {
    //creating PrintStream object
    PrintStream ps = new PrintStream(System.out);
    ps.println("Hello World!");
    ps.print("Hello World Again!");
    //Flushes the stream
    ps.flush();
  }
}
