What are the Operators in Java?

Operator in Java is a symbol or a sign which is used for performing operations. For example: -, +, /, * etc. In Java there are many different types of operators which are given below:-

  • Assignment Operator
  • Arithmetic Operator
  • Relational Operator
  • Logical Operator
  • Bitwise Operator
  • Unary Operator
  • Ternary Operator

Assignment Operators In Java :-

Assignment = operators are used to assigns the value on its left variable to the right side variable or data. Assignment operators in Java are given below:

Operator Example Equal To Explain
= a = b; a = b; It takes the value of b and assigns into a.
+= a += b; a = a + b; It takes the value of a + b and assigns into a.
-= a -= b; a = a - b; It takes the value of a - b and assigns into a.
*= a *= b; a = a * b; It takes the value of a * b and assigns into a.
/= a /= b; a = a / b; It takes the value of a / b and assigns into a.
%= a %= b; a = a % b; It takes the value of a % b and assigns into a.

Example:

 
    import java.io.*;
    Class Main{  
     Public static void main(String args[]){  
       int a = 12, b = 5;
       int c = 12, d = 5; 

       a += b;
       c %= d;  

       System.out.println(a);
       System.out.println(c);         
     }
    }

Output

    17
    2

Arithmetic Operators In Java :-

Arithmetic operators are used to perform arithmetic operations on two or more variables. Arithmetic operators in Java are given below:

Operator Operation
+ It adds two or more variables / values one with others.
- It subtracts two or more variables / values on from another
* It multiplies two or more variables / values one with others.
/ It division two or more variables / values one by anothers.
[N:B If you use the division operator with two integers, then the result will also be an integer. And, if atleast one of the operands is a floating point number, you will get the result will also be in floating point. ]
% Modulo Operation is basically keep the remainder.

Example:


    import java.io.*;
    Class Main{  
     Public static void main(String args[]){  
      int a = 12, b = 5;
      float c = 12, d = 5;
      int Addition = a + b; // addition operator
      int Substract = a - b; // subtraction operator
      int Multiplication = a * b; // multiplication operator
      float Division = c / d; // division operator
      int Modulo = a % b; // modulo operator
    
      System.out.println("a + b = "+ Addition);
      System.out.println("a - b = "+ Substract);
      System.out.println("a * b = "+ Multiplication);
      System.out.println("c / d = "+ Division);
      System.out.println("a % b = "+ Modulo);   
     }
    }

Output

    a + b = 17
    a - b = 5
    a * b = 60
    c / d = 2.4
    a + b = 2

Relational Operators In Java :-

Relational operators are used to check the relationship or comparison between two operands or variables. Relational operators in Java are given below:

Operator Description Example
== Is Equal To 5 == 5 will return true.
!= Is Not Equal To 5 != 4 will return true.
> Greater Than 5 > 4 will return true.
< Less Than 5 < 4 will return false.
>= Greater Than Equal To 5 >= 4 will return true.
<= Less Than Equal To 5 <= 4 will return false.

Example:


    import java.io.*;
    Class Main{  
     Public static void main(String args[]){  
      int a = 5, b = 4;
      System.out.println(a == b);
      System.out.println(a >= b);         
     }
    }

Output

    false
    true

Logical Operators In Java :-

Logical operators are used to check 2 or more expression is true or not. Logical operators in Java are given below:

Operator Example Description
&& (Logical AND) 5 > 4 && 9 > 3 If both side expression of && (AND) is true, then it returns true.
|| (Logical OR) 5 > 4 || 9 < 3 If any one side expression of || (OR) is true, then it returns true.
! (Logical NOT) !expression If expression is true, then it returns false and if expression is false then it returns true and vice versa.

Example:


  import java.io.*;
  Class Main{  
    Public static void main(String args[]){  
     int a = 5, b = 4, c = 1;
     System.out.println(a > b && b > c);
     System.out.println(a > b || b < c);
     System.out.println( !(a > b) );      
    }
 }

Output

    true
    true
    false

Bitwise Operators In Java :-

Bitwise operators in Java are used to perform operations on every bits. Bitwise operators in java are:

Operator Description
& Bitwise AND
| Bitwise OR
^ Bitwise XOR
~ Bitwise Complement
<< Bitwise Left Shift
>> Bitwise Right Shift
>>> Unsigned Right Shift

Unary Operators In Java :-

Unary operators are worked with one variable or operands. Unary operators in Java are given below:

Operator Description Example
++ Increment Operator If a = 4 then a++ will be 5.
-- Decrement Operator If a = 4 then a-- will be 3.

Example:


  import java.io.*;
  Class Main{  
    Public static void main(String args[]){  
     int a = 5, b = 4;
     System.out.println(a++);
     System.out.println(b--);   
    }
 }

Output

    6
    3

Ternary Operators In Java :-

Ternary operators is basically a conditional operator and sign is ?. For an example: 

    variable = expression ? value1 : value2;

In the above example if expression is true then value1 will be stored in variable and if expression is false then value2 will be stored in variable.

Example:


    import java.io.*;
    Class Main{  
     Public static void main(String args[]){  
        int a = 5, b;
        b = a < 3 ? 2 : 4
        System.out.println(b);  
     }
    }

Output

   4
