Flow Control - Programming

Q1:

What will be the output of the program? 
int i = 0; 
while(1) 
{
    if(i == 4) 
    {
        break;
    } 
    ++i; 
} 
System.out.println('i = ' + i);

A i = 0

B i = 3

C i = 4

D Compilation fails.

ANS:A - i = 0

Compilation fails because the argument of the while loop, the condition, must be of primitive type boolean. In Java, 1 does not represent the true state of a boolean, rather it is seen as an integer.
