Discussion Forum : Operators and Assignments - Finding the output (Q.No. 10)
10.
What will be the output of the program?
class SSBool
{
public static void main(String [] args)
{
boolean b1 = true;
boolean b2 = false;
boolean b3 = true;
if ( b1 & b2 | b2 & b3 | b2 ) /* Line 8 */
System.out.print("ok ");
if ( b1 & b2 | b2 & b3 | b2 | b1 ) /*Line 10*/
System.out.println("dokey");
}
}
Answer: Option
Explanation:
The & operator has a higher precedence than the | operator so that on line 8 b1 and b2 are evaluated together as are b2 & b3. The final b1 in line 10 is what causes that if test to be true. Hence it prints "dokey".

&& operator checks the next condition if the first will be true.
& operator checks all conditions whether the first is true or false.
So at Line 8 final output of if the condition expression is false
And at Line 10 final output of if the condition expression is true.
Therefore output would be "dokey".
