Stream:-
      Stream is a intermediator among input, output and user. All streams 
are represented by class in java.io package.
Streams are classified into two types
1) Input Stream
2) Output Stream

Input Stream:
   Data is received from input devices in sequences then it is called "input stream"
 or "Source Stream"
EX:- Keyboard

Output Stream:
   Data is passed output devices then it is called "output stream" or "Destination stream".
EX:- Monitor

Member Operator:-
    
This operator is also called as dot operator and it will represents
 the members of a package or class.

Syntax:- packagename.classname

Eg:- java.lang.System
     java.lang.String

 Every class have variables and members, we are using dot operator to represent 
the variable of a class and method of a class.


Syntax 1:-

  Variables of a class

classname.variable name

Eg:- System . out
     System . err

Syntax 2:-
 Methods of a class

classname.method name

Eg:- Math . Sqrt()

New Operator:-
          New operator is used for creating a object to the class.

 Syntax:- 
   class name obj = new class name();

Eg:- Employee e = new Employee();

Cast Operator:-
       It is used to convert the data from one data type to another data type.

Eg:- double q = 26.546;
     int x  = (int)a;

Lets see a example program on cast operator

class Cast 
{
public Static void main(String args[]);
{
double a = 26.546;
System.Out.println("the value of a=" +a);
int x=(int)a;
System.Out.println("the value of x=" +x);
}
}

Unary Operator
 
   The Unary Operators are as follows....
=> -
=> ++
=> --

We will see a program in JAVA on Unary Operators

class Unary
{ 
Public Static void main(Sring a[])
{
int a=10;
System.Out.println("the value of a="+a);
System.Out.println("the value of -a="+(-a));
System.Out.println("the value of ++a="+(++a));
System.Out.println("the value of a="+a);
System.Out.println("the value of a++="+(a++));
System.Out.println("the value of a="+a);
System.Out.println("the value of --a="+(--a));
System.Out.println("the value of a-- ="+(a--));
}
}

Can anyone predict the output of the program????????

Lets see about the remaining operators in our next post.
Have a tremendous Tuesday......

Increment and Decrement Operator:-
    

Increment Operator(++) :-
                    ++ is called increment operator and it is increases the
variable by '1'(one).
Java is supported to two types of increment operators:-
1) pre increment operator
2) post increment operator 
 
Pre increment operator:
   The ++ is placed before the variable then it is called pre increment operator.
Eg:- ++a, ++s

Post increment operator:
   The ++ is placed after the variable then it is called pre increment operator.
Eg:- a++, b++

Decrement Operator(++) :-
                      -- is called decrement operator and it is decreases the
variable by '1'(one).
Java is supported to two types of increment operators:-
1) pre increment operator
2) post increment operator 
 
Pre decrement operator:
   The -- is placed before the variable then it is called pre increment operator.
Eg:- --a, --s

Post decrement operator:
   The -- is placed after the variable then it is called pre increment operator.
Eg:- a--, b--

Boolean Operator:-
    
The following are the logical operators:-
* &
* |
* !

Boolean AND

Truth Table

        C1       C2      Output
       True    True     True
       False   True     False
       True    False    False
       False   False    False

  From the above table, we understand that the condition 1 and condition 2
are true then the output will be true,
otherwise it will be false.

Boolean OR

Truth Table

        C1       C2      Output
       True    True     True
       False   True     True
       True    False    True
       False   False    False


  From the above table, we understand that the condition 1 and condition 2
are false then the output will be false,
otherwise it will be true.

Boolean NOT

Truth Table

        C      Output
       True     False
       False    True

  From the above table, we understand that the condition is true then the output is
 false, if the condition is false then the output is true.

Logical Operator:-
    
The following are the logical operators:-
* &&
* ||
* !

Logical AND

Truth Table

        C1       C2      Output
       True    True     True
       False   True     False
       True    False    False
       False   False    False

  From the above table, we understand that the condition 1 and condition 2
are true then the output will be true,
otherwise it will be false.

Logical OR

Truth Table

        C1       C2      Output
       True    True     True
       False   True     True
       True    False    True
       False   False    False


  From the above table, we understand that the condition 1 and condition 2
are false then the output will be false,
otherwise it will be true.

Logical NOT

Truth Table

        C      Output
       True     False
       False    True

  From the above table, we understand that the condition is true then the output is
 false, if the condition is false then the output is true.

Conditional Operator:-
    
If the condition is true then expression 1 will be executed otherwise
 expression 2 will be executed.

Syntax:- condition ? exp 1 : exp 2

  Lets have a program on Relational Operator

class Conditional
{
Public Static void main(String args[])
{
int a=, b=35, max;
System.Out.println("the value of a="+a);
System.Out.println("the value of b="+b);
max= a>b ? a : b;
System.Out.println(" max of a,b=" +max);
}
}

Assignment Operators:-
    
The assignment operator is =
            We can assign the value right side of the expression to a left side of the
variable is called "Assignment Operator" 

Ex :- p = 23
      a = 46

Ternary Operators:-
The ternary operator is double equal to(==) 
   Left side of the expression is equivalent to right side of the expression, right expression 
is equal to left side of the expression. It is known as "ternary operator".

Ex :- s == 2
      p == 10

Relational Operator:-
    
The following are relational operators.....
=>  <
=>  >
=>  <=
=>  >=
=>  ==
=>  !=

  Lets have a program on Relational Operator

class Relational
{
Public Static void main(String args[])
{
int a=56, b=35;
System.Out.println("the value of a="+a);
System.Out.println("the value of b="+b);
System.Out.println(a+ "<" +b+ "=" +(a < b));
System.Out.println(a+ ">" +b+ "=" +(a > b));
}
}

Arithmetic Operator
 
   The Arithmetic Operators are....
=> +
=> -
=> *
=> /
=> %

We will see a program in JAVA on Arithmetic Operators

class Arith
{ 
Public Static void main(Sring a[])
{
int a=10, b=5;
System.Out.println("the value of a="+a);
System.Out.println("the value of b="+b);
System.Out.println("the value of a.b="+(a+b));
}
}

Lets see about the remaining operators in our next post.
Have a tremendous Tuesday......

      The operator is a symbol which is used for specific task.
Java supports the following types of operators.
=> Arithmetic Operators
=> Relational Operator
=> Assignment Operator
=> Conditional Operator
=> Logical Operator
=> Bitwise Operator
=> Boolean Operator
=> Unary Operator
=> New Operator
=> Member Operator

        Lets see briefly about the operators in the next post......
Have a happy day.

Good Morning Everyone.... Have a happy day....

Object Oriented:

    Java is an object oriented programming language, this means java programs use objects and classes,
A) Standalone programs (Applications)
B) Applets
    
      => Both programs are prepared with the " .class" extension.
      => Both require JVM to execute these Byte code.

Applets:-
======
   Applets are the programs written specially for the distribution over a network. These programs
 contain information delivered to the world and involve user interaction. For example order entry
 form, registration form mailing etc.

Applications:-
=========
    Applications are system programs i.e; these programs run in the background and don't
 involve user interaction. For example server
administration, security manager etc.
 

Java - Basic Points to Remember

  
     Java is an "OBJECT ORIENTED PROGRAMMING LANGUAGE" developed by
 "JAMES GASLING" at Sun Microsystems in the early 1990's.

Basic points of Java
* Java doesn't support the pointers.
* Java doesn't hold the C data types like struct, union and enumeration.
* Java doesn't have the C keywords goto, type def and size of.
* Java doesn't have preprocessors like C and hence it doesn't use
 #define, #include statements(or hrader files).
* Java has added new operators such as instance unsigned rightshift(>>>)
 and also have logical, conditional operators.
* Java added break and continue statements.
* Java has replaced the destructor function with finalize function.
* Java doesn't support multiple inheritance.A new function is added called as interface.
* Java doesn't support global variables.
