Hi,
When comparing two strings, how do you say String 1 is NOT equal to String 2? And also, when using an if statement, what type of OR do you use if you have String 1 equals String 2 OR String 2 equals String 3? TIA.

The method String.equals(String) returns a boolean. So, if you have String1 and String2, it returns true if String1 equals String2, false if not.
So, to do String1 not equal to String2, you could do:
String1.equals(String2) == false
For the OR:
if ((String1.equals(String2)) | | (String2.equals(String3)))

if ((String1.equals(String2) == false) | | (String2.equals(String3) == false)) {
...
}

if(!string1.equals(string2))
do this;

if(string1.equals(string2)| | string2.equals(string3))
do this;
