|| is a type of Logical Operator and is read as “OR OR” or “Logical OR“. This operator is used to perform “logical OR” operation, i.e. the function similar to OR gate in digital electronics.
One thing to keep in mind is the second condition is not evaluated if the first one is true, i.e. it has a short-circuiting effect. Used extensively to test for several conditions for making a decision.
Syntax:
Condition1 || Condition2
// returns true if one of the conditions is true.
Below is an example to demonstrate || operator:
Example:
Java
import java.util.*;
public class operators {
public static void main(String[] args)
{
char ch = 'a' ;
if (ch >= 65 && ch <= 90
|| ch >= 97 && ch <= 122 )
System.out.println(
ch
+ " is an alphabet." );
else if (ch >= 48 && ch <= 57 )
System.out.println(
ch
+ " is a digit." );
else
System.out.println(
ch
+ " is a special character." );
}
}
|
Output:
a is an alphabet.
