What's the meaning of System.out.println in Java?

Question

Is this static println function in out class from System namespace?

namespace System {
  class out {
    static println ...         


        

Answer 1

System is a class, that has a public static field out. So it's more like

class System 
{
    public static PrintStream out;
}

class PrintStream
{
    public void println ...
}

This is a slight oversimplification, as the PrintStream class is actually in the java.io package, but it's good enough to show the relationship of stuff.
