System:System is predefined class in java.lang package.
out: out is final and static variable in system class and
it is a referece variable in PrintStream class.

we call the static varible with their class names.i.e
System.out
println():

println() is a method in PrintStream class so we can call
this method by using the reference variable i.e
System.out.println().
