Question

what is application of short circuit in Java
​

Answer 1

Answer: here is your answer

Explanation:CODE

class ShortCircuitAnd

{

   public static void main(String arg[])

   {

       int c = 0, d = 100, e = 50; // LINE A

       if( c == 1 && e++ < 100 )

       {

           d = 150;

       }

       System.out.println("e = " + e );

   

   }

}

OUTPUT

e = 50

DESCRIPTION

Since c is 0, which is not equal to one, the left hand operand is false and hence right hand operand is not evaluated and hence e is not incremented. But if c is set to 1, then left hand operand will be true and hence right hand operand will be evaluated, thus incrementing e, hence the output will be e = 51

THINGS TO TRY

   Change the value of c to 1 in LINE A and see that the output will be e = 51

   Change the value of c to 0 in LINE A and use logical AND (&) instead of short-circuit AND (&&) and see that the output will still be e = 51
