Three Letter Acronyms

[ryanisilly]

Hi guys, I'm in an intro comp sci class and been trying to do this problem for hours.
If anyone could give me some help on it, it would be really appreciated.[/img]

What have you tried so far?

[ryanisilly]

My main problem is just that I have no idea how to write my own method that does #2. I've missed some classes and all of question #2 is foreign language to me.

[Insectoid]

Do you know how to write a method? Do you know what a boolean is? What about a char?

[ryanisilly]

I think so, would it look something like this?

private static void isUpperLetter(

[Insectoid]

Well that's the first part of it. You want it to return a boolean though, not void.

[ryanisilly]

Sooo something like this then?


private static return isUpperLetter(

From there I have no idea.

For now, you want to declare functions using this template:

private static returnType functionName ( arguments )

For a function like isUpperCase or isTLA, the return type would be boolean -- either true or false, but no other values.

Since your function has a return type (other than void), you must make sure that the function eventually hits a return statement, and that the value you return is of the same type as the declared return type of the function.

Start with this:

code:

private static boolean isTLA ( String input ) {     return true; }

Once you get your program compiling, you can replace the "return true;" line with something that actually checks the requirements from your assignment (has exactly three letters, and all three are upper case, etc).
