explain System.out.println
Answer Posted / neojava
System is a built-in class present in java.lang package.
This class has a final modifier, which means that, it cannot
be inherited by other classes.
It contains pre-defined methods and fields, which provides
facilities like standard input, output, etc.
out is a static final field (ie, variable)in System class
which is of the type PrintStream (a built-in class, contains
methods to print the different data values).
static fields and methods must be accessed by using the
class name, so ( System.out ).
out here denotes the reference variable of the type
PrintStream class.
println() is a public method in PrintStream class to print
the data values.
Hence to access a method in PrintStream class, we use
out.println() (as non static methods and fields can only be
accessed by using the refrence varialble)
