    Default One simple question...

    how would you answer the following question?

    "Every variable in a Java program must have a ___________, which indentifies the kind of data that it will store."

    would "declaration" be a valid answer to this question?

    what would be the best answer?

    I guess the bigger question is, why do you think it would be declaration? The latter part of the question is a big hint itself - what identifies the kind of data a variable will store? See Primitive Data Types (The Java™ Tutorials > Learning the Java Language > Language Basics)

    so what does that response mean? do you think that the correct answer is "type" or do you think that "declaration" is correct, or both?

    What that response was meant to do was to encourage to think about the question. What does declaration mean in the java language? What does variable mean? What does type mean? See java.sun.com/docs/glossary.html

    I know what they all mean... A declaration requires just 2 things, a type, and a variable name. Pls answer what you think is correct.

    We aren't going to do your homework for you. You've been given a fantastic resource; I recommend you use it. Read through that tutorial and then tell us what you think it is- does a declaration identify the kind of data a variable will store? Or is it something else?

    as far as I know a declaration does exactly that, it defines a variable's type and gives it a name.

    If it was a test question, didn't the teacher tell you the correct answer? Did you put declaration down? Did it get marked right or wrong?

    A declaration defines a variable's type and its name, but the question didn't ask about the name. It only asked about the kind of data stored in the variable.

    To be honest the question could probably be answered either way. One of them is more specific though, so which is correct really depends on your teacher.

    just because i asked a simple question is no reason to talk down to me.

    the teacher said that declaration was wrong, but the way the question was worded i think that either one would be correct; declaring a variable defines it's type.

    I have no problems with simple questions. But you've been given great resources and answers, so the rest is on you. I haven't talked down to you, but the burden is on you to define each, let us know what you think, why you think it, etc. Actually, I gave you pretty much a completely full answer, and you're still complaining. Why would people want to continue helping somebody like that?

    Yes but the type is what defines what kind of data the variable will hold. The more specific answer is the more correct one.

    It's like if the test question had been "where is Washington DC?" and you answered "on Earth" when the teacher was looking for "in America" or even "right between Maryland and Virginia". Was your answer technically wrong? No. Should you get full credit for it? No.

    that post was in response to your previous one where you assumed wrongly that i was trying to get help with homework. look at the language, the whole thing is talking down, but yes, after that you were helpful.
