System is a final class in java.lang package, which is the
default package in Java.
out is a static variable in System class.
println() is a method of PrintStream class which is in
java.io package
in the system class
static printstream out;
so "out" acts as a reference for PrintStream class and also
static variable in System class.
so finally it produces the output to the console(character
using as input)
