A Simple Java program?

class Sample
public static void main (String args[] )
{
System . out .println (“
java is better than
c++);
}
Class declaration:
The first line
class Sample
- Declaration a class which are an object oriented construct.
- Java is true object oriented language and there fore every thing must be placed in side class
- Class is a keyboard declares that a new class definition follows. Simple is a java identifies that specific the no of the class to be defined.
Opening brace :-
Every class definition
in java beginnings
with an opening brace ( ) and ends
with a matching brace(}), appening in the last line.
The main line :-
The third
line
public static void
main (String args[])
Defines a method name main. This is similar to the
main function in c
language. Every java
application program must
be include the
main method. This is the starting point for the
interpreter to begin
the execution of
the program. A
java application can have
any number of
classes but only
one of them
must include a
main method, to initiate
the execution.
This line contains
a number of keywords public, static, void
Public:-
The keyboard public
is an axis specifics that declares the
main method has
un protected and
there fore making
it accessible to all other
classes.
Static:-
Next appears the keyboard
static. Which declares this
method as one
that belongs to
the entire class, and not 4 part of any objects
of the class. The main must
always be declared
as static since the interpreter uses this
method before any objects are
created.
Void:-
The type modifier
void states that
the main method doesn’t return
any value.
The output line
:-
The only executable
statement in the
above program is
System.
out. println
This is similar
to the printing statement in since java
is a true object oriented
package , every method must be
a part of
an object. the println
method is a member
of the out object, which is a data
member of system
class. This line prints the scan.
Java is better
than C ++
The method print
is always appends
a new line character.
This means any
sub request output will
start on a new
line.
