Boolean Operators

This article lists and explains boolean operators available in java.

 

 

Boolean operators 

Operators	Meaning
a && b	Conditional AND.  If both variables a and b are true, the result is true. If  either of the variable is false, the result is false. If a is false then b is not evaluated.
a & b	Boolean AND. If both variables are true, the result is true.  If either of the variable is false, the result is false.
a || b	Conditional OR. If either of the variable is true, the result is true. If a is true, b is not evaluated.
a | b	Boolean OR. If either of the variable is true, the result is true.
! a	Boolean NOT. If a is true, the result is false. If a is false, the result is true.
a ^ b	Boolean XOR. If a is true and b is false, the result is true. If a is false and b is true, the result is true. In other cade, the result is false.

Examples of Boolean Operators

Example 1 : Program that displays use of boolean operators i.e &&, &, ||, |, !, ^

class BoolOptrDemo

{ 

   public static void main(String args[])

   {

      boolean b1 = true;

      boolean b2 = false; 

      System.out.println("b1|b2 = "+(b1|b2));

      System.out.println("b1&b2 = "+(b1&b2));

      System.out.println("!b1 = "+(!b1));

      System.out.println("b1^b2 = "+(b1^b2));

      System.out.println("(b1|b2)&b1 = "+((b1|b2)&b1));

    }

}
