java-programmer, Trouble with the driver and classes that work with the driver.
this first part is the driver. need help with getting them both to work
with each other.
import java.util.Scanner;
public class AbbreviationsandStates
{
public static void main(String[] args)
{
String abbreIn;
String abbreOut;
String theResult;
EnterState es = new EnterState();
System.out.println("Enter Abbreviation the for the State : ");
Scanner in = new Scanner(System.in); //Instantiate Scanner
abbreIn = in.nextLine();
abbreOut = es.getAbbre(abbreIn);
theResult = es.getResult(abbreIn, abbreOut);
System.out.println(theResult);
}
}
this part is the class not sure what I am doing wrong but I do know that I
can not have an int for a string in the driver.
public class EnterState
{
public String getAbbre(String userInput)
{
userInput = userInput;
return userInput;
}
public int getResults(int abbre1, int abbre2)

Change this line to:
public static String getAbbre(String userInput)
and it will work. See http://java.sun.com/docs/books/tutorial/index.html
for more information.

Several nits:
1. Your second method does not seem to do quite what you want it to.
Characters should be passed as chars, not ints. Strings should be
returned as a String, not an int.
2. Try to be more descriptive than "they don't work."
3. Massive switch statements are not very ideal. Although the best was
would be to use a HashMap, since I assume that you are writing this as
part of an introductory class, that would probably be a bit beyond you
right now. At the very least, it is clearer to use code along the lines of:
// String abbreviation is passed in
abbreviation = abbreviation.toUpperCase();
if (abbreviation.equals("AL"))
return "Alabama";
else if (abbreviation.equals("AK"))
return "Alaska";
// etc.

Thanks for the help I will work on it tomorrow and let you know it works. I
was thinking of an hashtable but I can't use it.

see http://mindprod.com/jgloss/hashtable.html
http://mindprod.com/jgloss/hashmap.html
There is sample code, and lots of explanation of how they work inside.
