What will be the output of the program? boolean bool = true; if(bool = false) /* Line 2 / { System.out.println("a"); } else if(bool) / Line 6 / { System.out.println("b"); } else if(!bool) / Line 10 / { System.out.println("c"); / Line 12 */ } else { System.out.println("d"); }

Look closely at line 2, is this an equality check (==) or an assignment (=). The condition at line 2 evaluates to false and also assigns false to bool. bool is now false so the condition at line 6 is not true. The condition at line 10 checks to see if bool is not true (if !(bool == true) ), it isn't so line 12 is executed.
