P. 61
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 do basic mathematical calculations. These are known as binary
operators, which means they require two operands to perform calculations. 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.
Relational Operators
Relational operators help to compare quantities and return the Boolean value ‘True’ or ‘False’ as
a result. These are also known as binary operators.
Example
Operator Description Syntax Output
(int a = 11, b = 4)
== This is used to check the equality (a == b) a == b false
Equal to between two values. a == 11 true
