What is out is System.out.println

Question

Out resemble is small

Answer 1

Let's us understand this,
. Operator is used for call methods or variables

Methods in Java have parentheses so println is method and out is method

out is start with small letter so it is also not class name

So out must be variable name or object name

Since it is calling a method so it must be object name,

Since it is calling from class name System so it is static object

It is declared in Java as

Public static final PrintStream out;

here PrintStream is class

Let's a look a program for it

public class Goo{

public static String foo;

public static void setFoo(String foo)
{
this.foo=foo;
}}

int l=Test.foo.length(); for printing length

Answer 2

"System" is a final class from java.lang package.
"out" is a variable of type PrintStream inside the System class.
"println" is the method that does the printing on the console.
