This is what I got so far, am I on the right track?
Set entries = someObject.getItems().entrySet();
Iterator iterator = entries.iterator();
while (iterator.hasNext())
{
Map.Entry entry = (Map.Entry)iterator.next();

}

I need help on how to proceed this. I need to iterate through a hash map.
Thanks

Yes if it equals null I want to equal something other than null.
Thanks

Is this what you are asking?

How do you check for null for Short type?
I can't use 0 (zero).
???
Thanks

What do mean to add 2? Is this why I am being thrown a catch error? I edited the substring(0,indexOf(",")) to
substring(0, indexOf(",", -1)) to make it search from -1, didn't work still had a catch error.
Thanks

Is this correct? substring not subString, right?
I want strLastName to only equal the characters that precedes a comma (,):
strLastName = name.substring(0,name.indexOf(",")
This would extract characters after the comma to the end of the index:?
strFirstName = name.substring(name.indexOf(","))
Thanks.

Great job guys! Didn't expect it to be so heavy.
The classes are categories not java classes.
The value of the combination of these two classes is derived. The user does not enter it on the form. The values come from the database.
A 9/10 class is not the same as a 9 class and a 10 class.
A 9/10 class may have some items of 9 class and 10 class and it may have additional stuff that are not in 9 or 10. Confusing? Yes. But I don't question the business rules and policies. Just doing what they want and having them as Strings make more sense.
Great job!
Thanks

Here is a real simple question for someone simple minded as I am.
How do you get the first character of a string?
.substring(0) ???
or
.substring(1)???
I want to extract the first two
Thanks

Mike:
The value is a String comprised of two Strings
for example
strClass = strPrimaryClasss + "/" + strSecondaryClass
strClass could equal 9/10 or 9 only or 10 only.
There is a third String that would indicate whether strClass is just a primary, secondary or combination of both classes.
That's why it's a String, no calculations are done on these values.
Thanks.

It is a string because it does not involve calculations. It's a value getting off of a form.
Thanks.

I have a method that returns a String value. The values are only valid if it is 1-9. How do you do determine greater than and less than of a String?
for example: (I know this does not work)
if (myString.getString() > "0" && myString.getString < "10")
{
doSomething;
}
Thanks for any suggestions.

Please help me translate this shortcut code. I keep getting a null pointer exception. How do I check for a null pointer for a boolean?
<%=thisObject.isRequired()? "YES" : "NO"%>
Thank you for any help.

Figured it out the method is booleanValue()

Originally posted by christopher foran:
It returns a Boolean class. The Boolean class is not the same as the boolean primate. There is a method on the Boolean class which returns true/false.

If you have a return type Boolean what does this return, does it returns true/false like the primimtive boolean?
public java.lang.Boolean getIndicator()
{
return mIndicator;
}

What is exactly a map and how does it work? Does it has something to do with extracting data and matching field names to their values???
