WHAT WILL BE THE ANSWER AND WHY??
What will happen if you compile/run this code?
1: public class Q10
2: {
3: public static void main(String[] args)
4: {
5: int i = 10;
6: int j = 10;
7: boolean b = false;
8:
9: if( b = i == j)
10: System.out.println("True");
11: else
12: System.out.println("False");
13: }
14: }
A) Compilation error at line 9 .
B) Runtime error exception at line 9.
C) Prints "True".
D) Prints "Fasle".

C. it prints "True".
Because it assigns the equality test "i == j" (true) to the boolean value, which is then tested...

This is why, Because Equal Operator(==) is having heigher priority then assignment(=).So you got it,

Enjoy.

As much as I appreciate that this is a forum for beginners. I think when you have a question wich asks whether or not a piece of code will compile you should try to compile it yourself (the first thing a Java Programmer needs to learn to do"!) and see what the result is ... then if you get a unexpected result you can post on here ask why it did what it did. This shows that you have actully really put some thought into the issue and are not just looking for a "quick answer" to a question set for by someone else.
