System and out in java

Question

I am new java user. Recently I have learned that out (Which we use at System.out.println) is a java standard output object.

My question is; I never created this object by myself or haven't found any code which creates this object. So how it is accessible to use?

And more over I think System is a class name. If so, is out a static member of the System class, since we are accessing out without creating a new object of System class?

Answer 1

Yes, System is a class and out is a static member variable of that class.

public final class System {
    public static final PrintStream out = ...;
    public static final PrintStream err = ...;
    public static final InputStream in = ...;
    ...
}

See the Java documentation for System class

Answer 2

yep, this lives on the System object:

public final static PrintStream out = null;

Answer 3

A good way to learn a language (and to have the right answers) is to look at the API source. in System.java

...
public final static PrintStream out = null;
...

you don't need to create object in order to access static members
