  OPERATORS IN JAVA
• 3.
  OPERATORS • Operators arethe 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. LOGICALOPERATOR  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/ DECREMENTOPERATOR  ‘++’ 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 • inta=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.
