Given:
1. class Bool {
2.   static boolean b;
3.   public static void main(String [] args) {
4.      int x=0; 
5.      if (b ) {
6.       x=1;
7.      }
 
8.      else if (b = false) {
9.       x=2;
10.     }
11.     else if (b) {
12.      x=3;
13.     }
14.     else {
15.      x=4;
16.     }
17.     System.out.println("x = " + x);
18.   }
19. } 
 

wht is the result?
What is the result?





A
x = 0
B
x = 1
C
x = 2
D
x = 3
E
x = 4
F
Compilation fails

i answered x = 2. but the correct answer is x=4
i answered x=2, bcos b=false sets the value of b to false.so,doesnt the if loop return true?
plz explain.

"b=false sets the value of b to false"
You are correct, but what is the value of the expression

b = false
