boolean flag = false;

System.out.println("false");
}
a true is printed to standard out

The ans is d, But I think the ans should be A. Can anyone tell me the true?

true is being printed on my sys. because the if statement
if (flag = true) is assigning true to flag and the enitre value of the expression becomes true making if to pass through and print
"true".
