Java Bitwise Operators (&,|,^,~,!) / Chapter -7/Operator & Assignments

java bitwise operator

In JAVA there are five bitwise operators available.

1. Bitwise AND ( & )     [both boolean and integral type]


2. Bitwise OR    (  |  )      [both boolean and integral type]


3. Bitwise XOR  ( ^ )      [both boolean and integral type]


4. Bitwise Complement Operator ( ~ )   [only for integral types]


5. Bitwise Complement Operator ( ! )   [only for boolean types]

1. Bitwise AND ( & ):-

If we apply bitwise AND (&) between two arguments then if and only if it will return true if both arguments are true otherwise it will return false.

example for boolean:-

 

System.out.println(true & true );         output  is    true

 

System.out.println(true & false);         output  is    false

 

System.out.println(false & false);        output  is    false

example for integrals:-

 

System.out.println( 5  &  4);         output  is    4

 

reason:   5 in binary   101

               4 in binary    100        now applying AND Operation if both are true then only true.

            ――――――――--

result:                        100   means   4  that's we are getting 4 as the output.

 

 

 

2.Bitwise OR( | ) :-
If we apply bitwise OR( | ) between two arguments then if and only if it will return true if one argument is true.

example for boolean:-

System.out.println(true | false);           output  is    true

System.out.println(true | true );            output is true

 

example for integral:-

System.out.println( 5  |  6);         output  is    7

reason:   5 in binary  101

              6 in binary  110        now applying OR Operation if one is true then true.

            ――――――――

result:                        111     means   7 that's we are getting 7 as the output.

3. Bitwise XOR( ^ ):-
 If we apply bitwise XOR( ^ ) between two arguments then if and only if it will return true if both arguments are different otherwise it will return false.

example for booleans:

System.out.println(true ^ false);         output  is    true

System.out.println(true ^ true );         output  is    false

example for integrals:

 

System.out.println( 5  ^  6);         output  is    3

reason:      5 in binary   101

                6 in binary   110        now applying XOR Operation if both are different then only true.

            ――――――――-

result:                          011   means   3 that's we are getting 3 as the output.

4.Bitwise Complement Operator(~);-
This operator can be applied to the integral type only not for boolean type. If we are applying then we will get Compile-Time Error.

 

example:-

System.out.println(~4);         output is -5System.out.println(~true);
Compile-Time Error : Operator ~ cannot be applied to boolean

5.Bitwise Complement Operator(!);-
This operator can be applied to the boolean type only not for integral type. If we are applying then we will get Compile-Time Error.

example:-

System.out.println(!true);         output is  false

System.out.println(!4);
Compile-Time Error : Operator ! cannot be applied to int
