OPERATORS
Operators are used as symbols to direct the compiler or interpreter to carry out specific
mathematical, logical, or other operations. It uses operands (the values or variables involved
in the operation) to produce a result."
For example:
int x = y + z;
or
int x = 10 + 20;
In the above example, the plus (+) operator is used to calculate the sum of two variables (y and z)
or values (10 and 20). It calculates the sum and assigns the result to the variable x.
There are various types of operators in Java, which are as follows:
Arithmetic operators
Relational operators
Logical operators
Unary operators
Assignment operators
Let's discuss these in detail.
Arithmetic Operators
Arithmetic operators are used to perform basic mathematical calculations. They consist
of both unary operators, which operate on a single operand, and binary operators, which
require two operands. These are as follows:
Example
Operator Description Syntax Output
(int a = 11, b = 4)
+ Returns the result after performing the a + b a + b 15
addition addition operation
– Returns the result after performing the a – b a – b 7
subtraction subtraction operation
* Returns the result after performing the a * b a * b 44
multiplication multiplication operation
/ Returns the result after performing the a / b a / b 2
division division operation
% Returns the remainder after performing a % b a % b 3
remainder the division operation
