I agree, the 3rd solution is probably less efficient because it has to do an unnecessary concatenation (+). I also like solution 1 and 2 better since it's clearer what the code accomplishes.

the "DoNotTerminate" is an Exception which is used to prevent the code giving errors at the Runtime . it is very neccessarry and if you observe carefully that Exception is getting overloaded so that the errors can be neglected

I assume this problem was incorrectly marked as Difficult.
Yes, it should be marked as Easy.
hav u solved this?
yes...

Yes it was incorrect. Fixed now, thanks.
can you please explain the use of the DoNotTerminate class, as in why preventing us from terminating by exit(0) @Shafaet sir
I too am not getting why DoNotTerminate class was necessary, would like to know the explanation
You can just exit using return;

String s = ""; s = Integer.toString(n);
that's it.
You don't even need the String s = "". You can just do
right?
Yes.
String s=""+n;
I did this!. I'll try the parser, never seen it before... Ok its constant
String s = Integer.toString(n); is showing an error
toString() used for objects
Can't you just use String s = String.valueOf(n);
Yes we can.
really smart way
thanks sir
Yep, this is my favorite way.
Or, String s = String.valueOf(n);
I wonder if there's any difference between static String.valueOf and static Integer.toString...
Ok, looking at the source code,
Integer.toString
String.valueOf
String.valueOf just calls Integer.toString, so the only difference is an extra method invocation.
Yeah! Good point. And it's only a convenience feature where we can pass any datatyped-value I guess..
It's better to use valueOf, because you will never get NPE.
Yes! Integer.toString(); Is always prefered here
yes
That's good content. I like it much abcya
Also could be: String s = ""; s = s.valueOf(n);
or simply, String s = "" + n;
This was my solution as well.
String str = String.valueOf(12);
The code is insufficient as explained in the link http://javadevnotes.com/java-integer-to-string-examples

Perfect. if someone is about to start their career in Java can join this forum for getting a lot of free resources.
What a great resource thanks!
String s = null; if(n>=-100 && n<=100){ s = String.valueOf(n);
}
