Operator Problem

[Ritu Kapoor]

What will be the output of the following program. Please tell me the reasons also.

Code
--------------------------------------------------------------------------
class Lang21 {
static boolean a, b, c;
public static void main (String[] args) {
boolean x = (a = true) || (b = true) && (c = true);
System.out.print(a + "," + b + "," + c);
}
}
---------------------------------------------------------------------------

output:
true, false, false

||,&& are short circuits operators, so after || it will stop the evaluation.

If you duplicate the line . . .

System.out.print(a+ " "+b+" "+c);

. . . in the first line in the method main(), then you will get a clear picture of what is going on. By default, the class variables are false. The code does something that makes one class variable true.

Your answer is true, false, false


<b>The || operator evaluates its right-hand operand only
if the value of its left-hand operand is false</b>

But here the value on the left side is a true value

the statement <b>a=true</b> is making it true on left side...


I think, it will help u ...
