I wonder how this code works?

Question

I was going through java API in order to understand how System.out.println("Print this string"); works. I came to know that println is an instance method of PrintStream class. So, i created an instance of PrintStream (ps) and accessed println. My code works fine BUT i realized that i needed to pass System.out as parameter to PrintStream constructor.
NOW System.out already refers to an instance of PrintStream class.
BUT there is no such constructor defined in PrintStream class that requires an instance of PrintStream as parameter (See API).
I wonder how this code works?
import java.io.*;
class AnotherWayToPrint {
     public static void main(String[] args) {
          PrintStream ps = new PrintStream(System.out);
          ps.println("Yes! I am printed.");
          ps.println(System.out); // java.io.PrintStream@1ob62c9
}

as parameter to PrintStream constructor.
NOW System.out already refers to an instance of
PrintStream class.
BUT there is no such constructor defined in
PrintStream class that requires an instance of
PrintStream as parameter (See API). Requires? All the constructors for PrintStream take an OutputStream as a parameter.
A PrintStream IS AN OutputStream
