0039 Boolean Logical Operators
<![CDATA[
The Boolean logical operators operate only on boolean operands.
Operator Result
& Logical AND
| Logical OR
^ Logical XOR (exclusive OR)
|| Short-circuit OR
&& Short-circuit AND
! Logical unary NOT
&= AND assignment
|= OR assignment
^= XOR assignment
== Equal to
!= Not equal to
? : Ternary if-then-else
The following table shows the effect of each logical operation:
A B A | B A & B A ^ B !A
False False False False False True
True False True False True False
False True True False True True
True True True True False False
The following program demonstrates the boolean logical operators.
public class Main {
public static void main(String args[]) {
boolean a = true;
boolean b = false;
boolean c = a | b;
boolean d = a & b;
boolean e = a ^ b;
boolean f = (!a & b) | (a & !b);
boolean g = !a;
System.out.println(" a = " + a);
System.out.println(" b = " + b);
System.out.println(" a|b = " + c);
System.out.println(" a&b = " + d);
System.out.println(" a^b = " + e);
System.out.println("!a&b|a&!b = " + f);
System.out.println(" !a = " + g);
}
}
The output:
a = true
b = false
a|b = true
a&b = false
a^b = true
!a&b|a&!b = true
!a = false
