Boolean Logical Operators

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:

Logical Operations

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

« The outcome of a relational operator is a boolean value.
