Re : classpath

Posted by Pierre on June 20, 2001 at 3:04 AM

> suppose i have a jar file called A.jar and it has a class called B. If I want to instantiate an object of B and call methods on it, what do I need to have? Do I need to include that file in my classpath? Do I need to write an import statement at the beginning of my java program? I am a newbie. plz let me know...

java -classpath dir;A.jar .....
where dir is the directory containing B.class
If you have declared that B is in a package
whith a : "package com.foo.bar;" line in B.java then
you shoud have for the compiled file a structure like that
dir
->com
->foo
->bar
B.class is in bar
if the class from where you call new B is in the same package
as B then you don't need an import statement.
otherwise you need an import com.foo.bar.*;
