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

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

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.
