2. OPERATORS IN JAVA

3. OPERATORS
• Operators are the predefined symbolic instructions
which are used to perform the operations on
operands (data).

4. Like ‘C’, ‘Java’ also support 8 types of operators
1. Arithmetic Operator
2. Relational / Comparison operator
3. Logical operator
4. Assignment operator
5. Increment /Decrement operator
6. Conditional operator
7. Bitwise operator
8. Special operator

5. 1. ARITHMETIC OPERATOR
 These operator are used to perform arithmetical operation.
Operator Name Symbol
Addition +
Subtraction -
Multiplication *
Division /
Modulus %

6. 2. RELATIONAL / COMPARISON OPERATOR
 These operator are used to compare two operands together.
Operator name symbol
Greater than >
Greater than equal to >=
less than equal to <=
less than <
Equal to ==
Not equal to !=

7.  3. LOGICAL OPERATOR
 These operator are used to combine two or more
condition together.
Operator name Symbol
AND &&
OR !!
NOT !

8. 4. ASSIGNMENT OPERATOR
 Equal to sign is called assignment operator it is used
to assign some value or expression into a variable.
 Assignment always take place right to left.
a=b
b=30
c=a+b

9. 5. INCREMENT/ DECREMENT OPERATOR
 ‘++’ is called increment operator and
 ‘- -’ is called decrement operator .
 It is used to increase or decrease the values of variable by 1.
a++ a=a+1// postfix notation
++a a=a+1// prefix notation
b-- b=b-1//postfix
--b b=b-1//prefix

10. Postfix Operator
• int a=5, b;
b=a++ a=6
Assignment at first b=5 and then decrement.
int a=4, b;
b=a-- ; a=3
b=4

11. Prefix Operator
int a=5, b;
B=++a; a=6
b=6
increment at first and then assigned
Example:- int a=4,b;
B=--a, a=3
b=3

12. 6. CONDITIONAL OPERATOR (‘?’ , ‘:’)
 ‘? :’ is simultaneously called as conditional operator.
 It is used to assign some value or expression into a
variable on some condition
 v= (condition ? Expression 1: expression 2);
 possible output 1. if true
 2. true value
 3. false value
 4. if false

13. • Int a=5, b=10,c;
C=(a>b? 50:40)
System.out.print (c); 40
C(a<b? A+b: a-b)
System.out.print(c); 15

14. 7. BITWISE OPERATOR
 These operator are used to perform the operation on bit values (0,1) so
these are specially used for bit level programming.
A). Bitwise logical
AND - &
OR - !
XOR - ^
B). Shift operator
left shift - <<
right shift - >>
C). Bitwise complement operator
NOT - ~ (TILDE)

15. 8. SPECIAL OPERATOR
 Comma(,) and “ instance of” are called as special operator.
 Comma (,); operator is not supported by java.
 int a,b,c ;
use of comma
 INATANCE OFF:- It is used to take whether an object belongs to
particular class or not.
