What will be the output of the program?
public class Demo27
{
void run()
{
boolean shouty = Boolean.parseBoolean("TRUE");
boolean affirmative = Boolean.parseBoolean("yes");
System.out.println(shouty + " " + affirmative);
}
public static void main(String[] args)
{
new Demo27().run();
}
}
Answer: C
parseBoolean compares against the text true ignoring case, so TRUE gives true. Anything else, including yes, gives false rather than throwing. The method has no notion of other affirmative words and never reports a parse failure.
