how to know which jars the import commands are dependent on

[liber77]

If you have some import statements in the beginning of a .java file, how do you know which .jars you have to use when you compile?

[kevinn205]

Do you compile by hand program or IDE or application?

Java can come with alot of the stuff like import javax.swing.JFrame etc no need to specifitly compile them with IDE's, if you looking at doing it by hand ill let someone more qualified answer

if your looking to compile useing a IDE i would reccomend using eclipse all you have to do is specify where the jar is located and it adds it to the library,
whenever you create a executable jar it compiles all the necessary ones that you located, anytime you use a outside source your gonna need to locate it

The document should explain that. If you are using a third party JAR file, then you have to add them into the class path before import into your class. (I am talking with relevant to use of the command prompt and simple text editor.) If you are using an IDE it will done the job for you, and simply what you have to do it point them to the IDE.

Exactly what I want to point. But I have one recommendation. When you are doing this import all the JARs as global entity, rather project specific. Hope Eclipse could do it.
