Discussion Forum : Operators and Assignments - Finding the output (Q.No. 9)
9.
What will be the output of the program?
class Bitwise
{
public static void main(String [] args)
{
int x = 11 & 9;
int y = x ^ 3;
System.out.println( y | 12 );
}
}
Answer: Option
Explanation:
The & operator produces a 1 bit when both bits are 1. The result of the & operation is 9. The ^ operator produces a 1 bit when exactly one bit is 1; the result of this operation is 10. The | operator produces a 1 bit when at least one bit is 1; the result of this operation is 14.

helo jasmin..here is the explanation
write numbers in binary
0000
0001
0010
....
....
....
1111
so we want to find out 11&9.
ie 1001
1000
----
1000----->9
using this value we can find y in successive operations as explained.
i think its a good question..thank you

11 in binary form is 1011
9 in binary form is 1001
so 11&9=1001 ie equals 9
and y=x^3 ==
x value is 9 then
y=9^3==1001(ie 9 binary value)
0011(ie 3 binary value)
so y=1011 ie equals to 11
then y|12 is equals to 11|12 == 1011
1100
==15 so the =answer is 15
9 in binary form is 1001
so 11&9=1001 ie equals 9
and y=x^3 ==
x value is 9 then
y=9^3==1001(ie 9 binary value)
0011(ie 3 binary value)
so y=1011 ie equals to 11
then y|12 is equals to 11|12 == 1011
1100
==15 so the =answer is 15

Do smart work by looking at options we can say tht first three ans are lesser than 12 while doing OR operation the value will automatically increase.

1001 = (x=9)
0011 = 3
1010 = (y=9^3)
1100 = 12
1110 = y|12
0011 = 3
1010 = (y=9^3)
1100 = 12
1110 = y|12

What the function ^ is does ?
JaiShriRam said:

Mansi Jain: ^ is EX-OR function,
which means if toggle answre is 1 else 0
eg: 9^3 ==
1001
0011
------
1010 == number 10
ook when the binary digit are same,
we get 0 as resut, when they toggle we get 1.
which means if toggle answre is 1 else 0
eg: 9^3 ==
1001
0011
------
1010 == number 10
ook when the binary digit are same,
we get 0 as resut, when they toggle we get 1.

Binary of(11)=1011
Binary of (9)=1001
Perform & ------
Result X=1001 which is in decimal(9)
Now X^3 where x=1001
Binary of(3) = 0011
Perform ex-or ------
Result Y=1010 which is in decimal(10)
Now perform (Y|12)=1010
Binary of (12) = 1100
Perform or(|) -----
Result = 1110 which is in decimal (14).
Hence the ans is 14.
Binary of (9)=1001
Perform & ------
Result X=1001 which is in decimal(9)
Now X^3 where x=1001
Binary of(3) = 0011
Perform ex-or ------
Result Y=1010 which is in decimal(10)
Now perform (Y|12)=1010
Binary of (12) = 1100
Perform or(|) -----
Result = 1110 which is in decimal (14).
Hence the ans is 14.
