Thread: Counting the number of statement in java code

Hello folks,

I have started learning java, and this might be a really easy question, is there any a correct way to count the number of statements in Java code and to count the number of statements which have been executed?

I am studying about 'statement coverage' and want to understand this concept.

For example how may statements are there in the following code?

Printsum (Int a, Int b) { ------------ Printsum is a function
Int result = a+ b;
If (result> 0)
Print ("Positive", result)
Else
Print ("Negative", result)
}

This is how I would count the number of statements:

1). Printsum (Int a, Int b) { ------------ Printsum is a function
2). Int result = a+ b;
3). If (result> 0)
4). Print ("Positive", result)
Else
5). Print ("Negative", result)
}

Some statements are in turn made up of other sub statements. So while the "If Else" is a statement it is also made up of the sub statements numbers 4 and 5.

Do a search for "Java railroad diagram". It will describe what to count as statements. As for automatically counting the number of statements in a class you might try using the "abstract syntax tree" for that class but I'm not 100% sure it will give you exactly what you are looking for.
