Jtips Question

[Thiru Narayanan]

public class Q1 {
static void processorB() {
System.out.println(" is a boolean Operator.");
}

static Q1 processorA(){
Q1 q=null;
if (("java").startsWith("null"))
return q;
else
return null;
}

static {
System.out.print("Java".startsWith(""));
}

public static void main(String[] args) {
processorA().processorB();
}
}
The answer for this program is given as "true is a boolean operator". Can anyone please explain how it comes?
This one is one of the toughest I have encountered so far! I thought the answer should be only "is a boolean operator"

Hi Thiru,
The first thing that gets run on class loading is any static blocks. Your code has a static block that prints out a boolean value.
"Java".startsWith( "" )
Since the string "Java" does start with "" (empty string) the result is true. That is why your output starts with the string "true".
You seem to understand the rest so I won't bother to continue ...
Regards,
Manfred.

Thank you Manfred.
I was under the impression that the static block will just print the empty string. Overlooked the fact that startsWith() method returns a boolean value.
