About boolean in java
I have always seen people having problem with the boolean in Java. Boolean can be effective to compress the size of your Java program. Here I have tried to give you a simple idea about boolean to clear confusions about boolean.
What is boolean?
There are eight type of primitive data types in Java(Read detail here) . Boolean is one of those primitive data types. It can have two possible values: true and false. The values of a boolean is written with the reserver words true and false.
comparison operators:
Comparison operators are used to compare the primtive values.
| Op | Name | Meaning |
|---|---|---|
i < j |
less than | 6 < 24 is true. |
i <= j |
less than or equal | 6 <= 24 is true. |
i == j |
equal | 6 == 24 is false. |
i >= j |
greater than or equal | 10 >= 10 is true. |
i > j |
greater than | 10 > 10 is false. |
i != j |
not equal | 6 != 24 is true. |
comparison operators are also used to compare the values of booleans.
Logical operators:
| Op | Name | Meaning |
|---|---|---|
a && b |
and | The result is true only if both a and b are true. |
a || b |
or | The result is true if either a or b is true. |
!a |
not | true if a is false and false if a is true. |
Happy Programming…. 🙂
