Yep, normally called as unclosed character literal.

So what is the different of,

Code:

        System.out.println((String)"Java");

and,

Code:

        System.out.println("Java");

There is no difference. Just casting confused. I see lots of time newbies confused on this. actually println() do all those things for you.

Oh Quiz Time

I AM BACK !!!

[rjuyal]

who is going to take the honor to sum up all the puzzles and there answer along with incorrect one as well as cool moments of this thread ...

[Eranga]

I don't think it's much better. We do this just to catchup something. Some answers are not given honestly, try to pointed something. Isn't it?

So it's better to keep going like this.

[rjuyal]

predict the output!! an as rule says, don't compile it just see and post the answer

Code:

package com.faaltu.Quiz;

public class StringInternTest {
	public static void main(String[] args) {
		String str1 = "string";
		String str2 = new String("string");
		String str3 = new String("string").intern();
		
		if ( str1 == str2){
			System.out.println("\nSAME");
		}else{
			System.out.println("\nNEAH");
		}
		
		if ( str1 == str3){
			System.out.println("\nSAME");
		}else{
			System.out.println("\nNEAH");
		}
		
		if ( str2 == str3){
			System.out.println("\nSAME");
		}else{
			System.out.println("\nNEAH");
		}
			
	}
}

	}
}

SAME

SAME

SAME

because you are using intern()........which causes new String object to point existing one if any exist.

[rjuyal]

es el correcto!


next puzzle please

[Eranga]

Hi, guys. I'm back here.

I would like to make a request from all of you guys. Please don't use PHP tags when posting codes or quotes in forums. It's make the browser keep too wide on the scree.

Thanks
Eranga

[rjuyal]

Code:

package com.faaltu.temp;

public class IntegerTest {
	public static void main(String[] args) {
		System.out.println("constructor: " + new Integer("hello"));
		System.out.println("parsing: " + Integer.parseInt("hello"));
	}
}

what will be the output?
and as the rule say "Don't compile it, just read and try to answer"!!

[Eranga]

Ah, I caught you

You comes with NumberFormatException. Required a integer value, but found a String object there in the second println().

Actually you need a String there. But it should be containing an int representation.

Is that my explanation is ok?

[Jesdisciple]

LOL, still waiting eh?

I think it would print "no" because == compares objects and the two strings are actually different objects with identical values under the hood.

[Eranga]

On which question are you talking about?
