boolean question from John Junt Mock Exam

[may leung]

boolean flag = false;
if (flag = true) {
System.out.println("true");
} else {
System.out.println("false");
}
a true is printed to standard out
b false is printed to standard out
c An exception is raised
d Nothing happens
The ans is d, But I think the ans should be A. Can anyone tell me the true?

[sasi dhulipala]

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".
