Operators in Java with example

Operators in Java:

An operator is a symbol that tells the computer to perform certain mathematical or logical manipulations. It is used in programs to manipulate data and variables. It supports a rich set of operators. Java operators can be classified into 8 categories are:

Arithmetic operators: This Operators are used to construct mathematical expressions as in algebra. Java provides all the basic arithmetic operators.

Operator	Meaning
+	Addition
-	Subtraction
*	Multiplication
/	Division
%	Remainder

Relational operators:
When we compare two quantities and depending on their relation, then we used some relational symbols that say called Relational Operators. It has the following syntax:

variable-name relation-operator value;

Operator	Meaning
<	less than
<=	less than or equal to
>	greater than
>=	greater than or equal to
(==)	equal to
!=	not equal to

Logical Operators:
An expression that combines two or more relational expressions is called Logical Operators or Compound Operators.

Operator	Meaning
&&	logical AND
||	logical OR
!	logical NOT

Assignment Operators:
This Operators used to assign the value of an expression to a variable. It has the following syntax:

variable = value;

Increment and decrement operators:
Java has two useful operators and these are the Increment and decrement operators. It has the following syntax:

variable+ +  // increment operator

and

variable--  // decrement operator

Example of Increment Operator:

i = i + 1;
same as
++i; or i++; // increment operator

Example of Decrement Operator:

i= i - 1;
same
--i; or i--  // decrement operator

Conditional Operators:
The character pair ?: is a ternary operator. It used to construct conditional expressions that says called Conditional Operators. It has the following syntax:

expression1 ? expression2 : expression3;

Special Operators:
Java supports some special operators such as instanceof opeartor and member of selection operator or dot operator (.) . It has the following syntax:

obj1 instanceof obj2;

Bitwise Operators:
Java has a distinction of supporting special operators that are known as Bitwise Operators. It used to manipulate data at values of bit-level and also used for testing the bits or shifting them to the right or left. Bitwise Operators may not be applied to float or double data types.

Operator	Meaning
&	bitwise AND
!	bitwise OR
^	bitwise exclusive OR
~	One's Complement
<<	Shift left
>>	Shift right
>>>	Shift right with zero fill
