Thread: If? Or ELSE!

Howdy,
Here is my problem, I have to ask the 'user' of the program a yes or no question. They must answer yes or no, therefore a scanner class is sufficient here, done all that. But, now I want my program to tangent in different ways depending on their answer. If they answer no, NO, NO!!!, nO or n, I want all these to work if they answer like this, same for Yes, Y, yes etc.

If they answer yes I want my program to be able to continue, if they answer no, I want it to end how I please. I just don't know whether or not i need to use "if" or "else", or some sort of loop or what?

This may be a very simple problem for you guys but I am new to java, if anyone could give me an answer to these problems It would mean alot, thanks.

lol, I have no idea how to do that.
Would be able to write a quick code for an example?

Thanks

It is easy. To convert the string to lower case:

str = str.toLowerCase();

To remove whitespaces at the beginning and the end.

str = str.trim();

Check if a string starts with something:

if (str.startsWith( "something" ))
    // Code here, lol

The last one I am not sure about, but you could replace the ! character with nothing like this:

str = str.replace("!", "");

And then check the length with the .length() method of the string. Of course, there may be better ways and I do not have the time to actually check if it works now because I am in a hurry. Hope this cleared things up.
