1.  The function below takes a String as a parameter and returns a new String
that is the reverse of the original.  Rewrite this function so that it uses
a for loop instead of a while loop:

String reverse(String s){
	int index = s.length()-1;
	String result = "";
		
	while( index >= 0 ){
		result += s.charAt(index);
		index--;
	}
		
	return result;
}

2. You write the function below that is supposed to take a person's first name and last name and
whether or not the first name should come first.  It should then return a String with the names
all capitalized in the appropriate order.

For example, a call: name("Dave", "Kauchak", true)

should give you: "DAVE KAUCHAK"

and a call: name("Dave", "Kauchak", false)

should give you "KAUCHAK, DAVE"

The function:

String name(String first, String last, boolean firstNameFirst){
	first.toUpperCase()
	last.toUpperCase()

	if( firstNameFirst ){
		return first + " " + last;
	}else{
		return last + ", " + first;
	}
}

You try it out:

name("Amy", "TheProgrammer", false)

and get "TheProgrammer, Amy", which is not right (it should be all caps!).

a) What do you think the problem is?  If you need a hint, take a look at the documentation for the String class:

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html

b) How should you fix this (i.e. rewrite the function above so that it works correctly)?
